Parameters
c2coff	string Enables or disables Simplified and Traditional Chinese Search. The default value for this parameter is 0 (zero), meaning that the feature is enabled. Supported values are: 1: Disabled 0: Enabled (default)
cr	string Restricts search results to documents originating in a particular country. You may use Boolean operators in the cr parameter's value. Google Search determines the country of a document by analyzing: the top-level domain (TLD) of the document's URL the geographic location of the Web server's IP address See the Country Parameter Values page for a list of valid values for this parameter.
cx	string The Programmable Search Engine ID to use for this request.
dateRestrict	string Restricts results to URLs based on date. Supported values include: d[number]: requests results from the specified number of past days. w[number]: requests results from the specified number of past weeks. m[number]: requests results from the specified number of past months. y[number]: requests results from the specified number of past years.
exactTerms	string Identifies a phrase that all documents in the search results must contain.
excludeTerms	string Identifies a word or phrase that should not appear in any documents in the search results.
fileType	string Restricts results to files of a specified extension. A list of file types indexable by Google can be found in Search Console Help Center.
filter	string Controls turning on or off the duplicate content filter. See Automatic Filtering for more information about Google's search results filters. Note that host crowding filtering applies only to multi-site searches. By default, Google applies filtering to all search results to improve the quality of those results. Acceptable values are: 0: Turns off duplicate content filter. 1: Turns on duplicate content filter.
gl	string Geolocation of end user. The gl parameter value is a two-letter country code. The gl parameter boosts search results whose country of origin matches the parameter value. See the Country Codes page for a list of valid values. Specifying a gl parameter value should lead to more relevant results. This is particularly true for international customers and, even more specifically, for customers in English- speaking countries other than the United States.
googlehost	string Deprecated. Use the gl parameter for a similar effect. The local Google domain (for example, google.com, google.de, or google.fr) to use to perform the search.
highRange	string Specifies the ending value for a search range. Use lowRange and highRange to append an inclusive search range of lowRange...highRange to the query.
hl	string Sets the user interface language. Explicitly setting this parameter improves the performance and the quality of your search results. See the Interface Languages section of Internationalizing Queries and Results Presentation for more information, and (Supported Interface Languages)[https://developers.google.com/custom-search/docs/xml_results_appendices#interfaceLanguages] for a list of supported languages.
hq	string Appends the specified query terms to the query, as if they were combined with a logical AND operator.

lr	string Restricts the search to documents written in a particular language (e.g., lr=lang_ja). Acceptable values are: "lang_ar": Arabic "lang_bg": Bulgarian "lang_ca": Catalan "lang_cs": Czech "lang_da": Danish "lang_de": German "lang_el": Greek "lang_en": English "lang_es": Spanish "lang_et": Estonian "lang_fi": Finnish "lang_fr": French "lang_hr": Croatian "lang_hu": Hungarian "lang_id": Indonesian "lang_is": Icelandic "lang_it": Italian "lang_iw": Hebrew "lang_ja": Japanese "lang_ko": Korean "lang_lt": Lithuanian "lang_lv": Latvian "lang_nl": Dutch "lang_no": Norwegian "lang_pl": Polish "lang_pt": Portuguese "lang_ro": Romanian "lang_ru": Russian "lang_sk": Slovak "lang_sl": Slovenian "lang_sr": Serbian "lang_sv": Swedish "lang_tr": Turkish "lang_zh-CN": Chinese (Simplified) "lang_zh-TW": Chinese (Traditional)

searchType	enum (SearchType) Specifies the search type: image. If unspecified, results are limited to webpages. Acceptable values are: "image": custom image search.
siteSearch	string Specifies a given site which should always be included or excluded from results (see siteSearchFilter parameter, below).
siteSearchFilter	enum (SiteSearchFilter) Controls whether to include or exclude results from the site named in the siteSearch parameter. Acceptable values are: "e": exclude "i": include
sort	string The sort expression to apply to the results. The sort parameter specifies that the results be sorted according to the specified expression i.e. sort by date. Example: sort=date.
start	integer (uint32 format) The index of the first result to return. The default number of results per page is 10, so &start=11 would start at the top of the second page of results. Note: The JSON API will never return more than 100 results, even if more than 100 documents match the query, so setting the sum of start + num to a number greater than 100 will produce an error. Also note that the maximum value for num is 10.
