|
|
* - hitsPerPage: (integer) Pagination parameter used to select the number of hits per page. Defaults to 20.
|
|
* - attributesToRetrieve: a string that contains the list of object attributes you want to retrieve (let you minimize the answer size).
|
|
* Attributes are separated with a comma (for example "name,address").
|
|
* You can also use a string array encoding (for example ["name","address"]).
|
|
* By default, all attributes are retrieved. You can also use '*' to retrieve all values when an attributesToRetrieve setting is specified for your index.
|
|
* - attributesToHighlight: a string that contains the list of attributes you want to highlight according to the query.
|
|
* Attributes are separated by a comma. You can also use a string array encoding (for example ["name","address"]).
|
|
* If an attribute has no match for the query, the raw value is returned. By default all indexed text attributes are highlighted.
|
|
* You can use `*` if you want to highlight all textual attributes. Numerical attributes are not highlighted.
|
|
* A matchLevel is returned for each highlighted attribute and can contain:
|
|
* - full: if all the query terms were found in the attribute,
|
|
* - partial: if only some of the query terms were found,
|
|
* - none: if none of the query terms were found.
|
|
* - attributesToSnippet: a string that contains the list of attributes to snippet alongside the number of words to return (syntax is `attributeName:nbWords`).
|
|
* Attributes are separated by a comma (Example: attributesToSnippet=name:10,content:10).
|
|
* You can also use a string array encoding (Example: attributesToSnippet: ["name:10","content:10"]). By default no snippet is computed.
|
|
* - minWordSizefor1Typo: the minimum number of characters in a query word to accept one typo in this word. Defaults to 3.
|
|
* - minWordSizefor2Typos: the minimum number of characters in a query word to accept two typos in this word. Defaults to 7.
|
|
* - getRankingInfo: if set to 1, the result hits will contain ranking information in _rankingInfo attribute.
|
|
* - aroundLatLng: search for entries around a given latitude/longitude (specified as two floats separated by a comma).
|
|
* For example aroundLatLng=47.316669,5.016670).
|
|
* You can specify the maximum distance in meters with the aroundRadius parameter (in meters) and the precision for ranking with aroundPrecision
|
|
* (for example if you set aroundPrecision=100, two objects that are distant of less than 100m will be considered as identical for "geo" ranking parameter).
|
|
* At indexing, you should specify geoloc of an object with the _geoloc attribute (in the form {"_geoloc":{"lat":48.853409, "lng":2.348800}})
|
|
* - insideBoundingBox: search entries inside a given area defined by the two extreme points of a rectangle (defined by 4 floats: p1Lat,p1Lng,p2Lat,p2Lng).
|
|
* For example insideBoundingBox=47.3165,4.9665,47.3424,5.0201).
|
|
* At indexing, you should specify geoloc of an object with the _geoloc attribute (in the form {"_geoloc":{"lat":48.853409, "lng":2.348800}})
|
|
* - numericFilters: a string that contains the list of numeric filters you want to apply separated by a comma.
|
|
* The syntax of one filter is `attributeName` followed by `operand` followed by `value`. Supported operands are `<`, `<=`, `=`, `>` and `>=`.
|
|
* You can have multiple conditions on one attribute like for example numericFilters=price>100,price<1000.
|
|
* You can also use a string array encoding (for example numericFilters: ["price>100","price<1000"]).
|
|
* - tagFilters: filter the query by a set of tags. You can AND tags by separating them by commas.
|
|
* To OR tags, you must add parentheses. For example, tags=tag1,(tag2,tag3) means tag1 AND (tag2 OR tag3).
|
|
* You can also use a string array encoding, for example tagFilters: ["tag1",["tag2","tag3"]] means tag1 AND (tag2 OR tag3).
|
|
* At indexing, tags should be added in the _tags** attribute of objects (for example {"_tags":["tag1","tag2"]}).
|
|
* - facetFilters: filter the query by a list of facets.
|
|
* Facets are separated by commas and each facet is encoded as `attributeName:value`.
|
|
* For example: `facetFilters=category:Book,author:John%20Doe`.
|
|
* You can also use a string array encoding (for example `["category:Book","author:John%20Doe"]`).
|
|
* - facets: List of object attributes that you want to use for faceting.
|
|
* Attributes are separated with a comma (for example `"category,author"` ).
|
|
* You can also use a JSON string array encoding (for example ["category","author"]).
|
|
* Only attributes that have been added in **attributesForFaceting** index setting can be used in this parameter.
|
|
* You can also use `*` to perform faceting on all attributes specified in **attributesForFaceting**.
|
|
* - queryType: select how the query words are interpreted, it can be one of the following value:
|
|
* - prefixAll: all query words are interpreted as prefixes,
|
|
* - prefixLast: only the last word is interpreted as a prefix (default behavior),
|
|
* - prefixNone: no query word is interpreted as a prefix. This option is not recommended.
|
|
* - optionalWords: a string that contains the list of words that should be considered as optional when found in the query.
|
|
* The list of words is comma separated.
|
|
* - distinct: If set to 1, enable the distinct feature (disabled by default) if the attributeForDistinct index setting is set.
|
|
* This feature is similar to the SQL "distinct" keyword: when enabled in a query with the distinct=1 parameter,
|
|
* all hits containing a duplicate value for the attributeForDistinct attribute are removed from results.
|
|
* For example, if the chosen attribute is show_name and several hits have the same value for show_name, then only the best
|
|
* one is kept and others are removed.
|
|
* @param delay (optional) if set, wait for this delay (in ms) and only send the query if there was no other in the meantime.

|

* @param settigns the settings object that can contains :
|
|
* - minWordSizefor1Typo: (integer) the minimum number of characters to accept one typo (default = 3).
|
|
* - minWordSizefor2Typos: (integer) the minimum number of characters to accept two typos (default = 7).
|
|
* - hitsPerPage: (integer) the number of hits per page (default = 10).
|
|
* - attributesToRetrieve: (array of strings) default list of attributes to retrieve in objects.
|
|
* If set to null, all attributes are retrieved.
|
|
* - attributesToHighlight: (array of strings) default list of attributes to highlight.
|
|
* If set to null, all indexed attributes are highlighted.
|
|
* - attributesToSnippet**: (array of strings) default list of attributes to snippet alongside the number of words to return (syntax is attributeName:nbWords).
|
|
* By default no snippet is computed. If set to null, no snippet is computed.
|
|
* - attributesToIndex: (array of strings) the list of fields you want to index.
|
|
* If set to null, all textual and numerical attributes of your objects are indexed, but you should update it to get optimal results.
|
|
* This parameter has two important uses:
|
|
* - Limit the attributes to index: For example if you store a binary image in base64, you want to store it and be able to
|
|
* retrieve it but you don't want to search in the base64 string.
|
|
* - Control part of the ranking*: (see the ranking parameter for full explanation) Matches in attributes at the beginning of
|
|
* the list will be considered more important than matches in attributes further down the list.
|
|
* In one attribute, matching text at the beginning of the attribute will be considered more important than text after, you can disable
|
|
* this behavior if you add your attribute inside `unordered(AttributeName)`, for example attributesToIndex: ["title", "unordered(text)"].
|
|
* - attributesForFaceting: (array of strings) The list of fields you want to use for faceting.
|
|
* All strings in the attribute selected for faceting are extracted and added as a facet. If set to null, no attribute is used for faceting.
|
|
* - attributeForDistinct: (string) The attribute name used for the Distinct feature. This feature is similar to the SQL "distinct" keyword: when enabled
|
|
* in query with the distinct=1 parameter, all hits containing a duplicate value for this attribute are removed from results.
|
|
* For example, if the chosen attribute is show_name and several hits have the same value for show_name, then only the best one is kept and others are removed.
|
|
* - ranking: (array of strings) controls the way results are sorted.
|
|
* We have six available criteria:
|
|
* - typo: sort according to number of typos,
|
|
* - geo: sort according to decreassing distance when performing a geo-location based search,
|
|
* - proximity: sort according to the proximity of query words in hits,
|
|
* - attribute: sort according to the order of attributes defined by attributesToIndex,
|
|
* - exact:
|
|
* - if the user query contains one word: sort objects having an attribute that is exactly the query word before others.
|
|
* For example if you search for the "V" TV show, you want to find it with the "V" query and avoid to have all popular TV
|
|
* show starting by the v letter before it.
|
|
* - if the user query contains multiple words: sort according to the number of words that matched exactly (and not as a prefix).
|
|
* - custom: sort according to a user defined formula set in **customRanking** attribute.
|
|
* The standard order is ["typo", "geo", "proximity", "attribute", "exact", "custom"]
|
|
* - customRanking: (array of strings) lets you specify part of the ranking.
|
|
* The syntax of this condition is an array of strings containing attributes prefixed by asc (ascending order) or desc (descending order) operator.
|
|
* For example `"customRanking" => ["desc(population)", "asc(name)"]`
|
|
* - queryType: Select how the query words are interpreted, it can be one of the following value:
|
|
* - prefixAll: all query words are interpreted as prefixes,
|
|
* - prefixLast: only the last word is interpreted as a prefix (default behavior),
|
|
* - prefixNone: no query word is interpreted as a prefix. This option is not recommended.
|
|
* - highlightPreTag: (string) Specify the string that is inserted before the highlighted parts in the query result (default to "<em>").
|
|
* - highlightPostTag: (string) Specify the string that is inserted after the highlighted parts in the query result (default to "</em>").
|
|
* - optionalWords: (array of strings) Specify a list of words that should be considered as optional when found in the query.
|
|
* @param callback (optional) the result callback with two arguments
|
|
* success: boolean set to true if the request was successfull
|
|
* content: the server answer or the error message if a failure occured

This file creates a global JSON object containing two methods: stringify
|
|
and parse.
|
|
|
|
JSON.stringify(value, replacer, space)
|
|
value any JavaScript value, usually an object or array.
|
|
|
|
replacer an optional parameter that determines how object
|
|
values are stringified for objects. It can be a
|
|
function or an array of strings.
|
|
|
|
space an optional parameter that specifies the indentation
|
|
of nested structures. If it is omitted, the text will
|
|
be packed without extra whitespace. If it is a number,
|
|
it will specify the number of spaces to indent at each
|
|
level. If it is a string (such as '\t' or ' '),
|
|
it contains the characters used to indent at each level.
|
|
|
|
This method produces a JSON text from a JavaScript value.
|
|
|
|
When an object value is found, if the object contains a toJSON
|
|
method, its toJSON method will be called and the result will be
|
|
stringified. A toJSON method does not serialize: it returns the
|
|
value represented by the name/value pair that should be serialized,
|
|
or undefined if nothing should be serialized. The toJSON method
|
|
will be passed the key associated with the value, and this will be
|
|
bound to the value
|
|
|
|
For example, this would serialize Dates as ISO strings.
|
|
|
|
Date.prototype.toJSON = function (key) {
|
|
function f(n) {
|
|
// Format integers to have at least two digits.
|
|
return n < 10 ? '0' + n : n;
|
|
}
|
|
|
|
return this.getUTCFullYear() + '-' +
|
|
f(this.getUTCMonth() + 1) + '-' +
|
|
f(this.getUTCDate()) + 'T' +
|
|
f(this.getUTCHours()) + ':' +
|
|
f(this.getUTCMinutes()) + ':' +
|
|
f(this.getUTCSeconds()) + 'Z';
|
|
};
|
|
|
|
You can provide an optional replacer method. It will be passed the
|
|
key and value of each member, with this bound to the containing
|
|
object. The value that is returned from your method will be
|
|
serialized. If your method returns undefined, then the member will
|
|
be excluded from the serialization.
|
|
|
|
If the replacer parameter is an array of strings, then it will be
|
|
used to select the members to be serialized. It filters the results
|
|
such that only members with keys listed in the replacer array are
|
|
stringified.
|
|
|
|
Values that do not have JSON representations, such as undefined or
|
|
functions, will not be serialized. Such values in objects will be
|
|
dropped; in arrays they will be replaced with null. You can use
|
|
a replacer function to replace those with JSON values.
|
|
JSON.stringify(undefined) returns undefined.
|
|
|
|
The optional space parameter produces a stringification of the
|
|
value that is filled with line breaks and indentation to make it
|
|
easier to read.
|
|
|
|
If the space parameter is a non-empty string, then that string will
|
|
be used for indentation. If the space parameter is a number, then
|
|
the indentation will be that many spaces.
|
|
|
|
Example:
|
|
|
|
text = JSON.stringify(['e', {pluribus: 'unum'}]);
|
|
// text is '["e",{"pluribus":"unum"}]'
|
|
|
|
|
|
text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
|
|
// text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
|
|
|
|
text = JSON.stringify([new Date()], function (key, value) {
|
|
return this[key] instanceof Date ?
|
|
'Date(' + this[key] + ')' : value;
|
|
});
|
|
// text is '["Date(---current time---)"]'
|
|
|
|
|
|
JSON.parse(text, reviver)
|
|
This method parses a JSON text to produce an object or array.
|
|
It can throw a SyntaxError exception.
|
|
|
|
The optional reviver parameter is a function that can filter and
|
|
transform the results. It receives each of the keys and values,
|
|
and its return value is used instead of the original value.
|
|
If it returns what it received, then the structure is not modified.
|
|
If it returns undefined then the member is deleted.
|
|
|
|
Example:
|
|
|
|
// Parse the text. Values that look like ISO date strings will
|
|
// be converted to Date objects.
|
|
|
|
myData = JSON.parse(text, function (key, value) {
|
|
var a;
|
|
if (typeof value === 'string') {
|
|
a =
|
|
/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
|
|
if (a) {
|
|
return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
|
|
+a[5], +a[6]));
|
|
}
|
|
}
|
|
return value;
|
|
});
|
|
|
|
myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
|
|
var d;
|
|
if (typeof value === 'string' &&
|
|
value.slice(0, 5) === 'Date(' &&
|
|
value.slice(-1) === ')') {
|
|
d = new Date(value.slice(5, -1));
|
|
if (d) {
|
|
return d;
|
|
}
|
|
}
|
|
return value;
|
|
});
