* @param args (optional) if set, contains an object with query parameters:
* - page: (integer) Pagination parameter used to select the page to retrieve.
* Page is zero-based and defaults to 0. Thus, to retrieve the 10th page you need to set page=9
* - 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.

* 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.

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 '&nbsp;'),
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;
