	//    parameter is only valid when you specify the sort option; it cannot be
	//    used in conjunction with buckets.
	//
	//    * sort specifies how you want to sort the facets in the results: bucket
	//    or count. Specify bucket to sort alphabetically or numerically by facet
	//    value (in ascending order). Specify count to sort by the facet counts

	// values, the facets are sorted by facet count, and the top 10 facets are returned
	// in the results.

	// counts by decade.
	//
	// {"year":{"buckets":["[1970,1979]","[1980,1989]","[1990,1999]","[2000,2009]","[2010,}"]}}

	// with the facet values that have the most matching documents listed first.
	// Setting the size option to 3 returns only the top three facet values.
	//
	// {"year":{"sort":"count","size":3}}
	//
	// To sort the facets by value, use the bucket option. For example, the following

	//    * max_phrases: specifies the maximum number of occurrences of the search
	//    term(s) you want to highlight. By default, the first occurrence is highlighted.
	//
	//    * pre_tag: specifies the string to prepend to an occurrence of a search
	//    term. The default for HTML highlights is <em>. The default for text
	//    highlights is *.
	//    * post_tag: specifies the string to append to an occurrence of a search
	//    term. The default for HTML highlights is </em>. The default for
	//    text highlights is *.
	// If no highlight options are specified for a field, the returned field text
	// is treated as HTML and the first match is highlighted with emphasis tags:
	// <em>search-term</em>.
	//
	// For example, the following request retrieves highlights for the actors and
	// title fields.
	//
	// { "actors": {}, "title": {"format": "text","max_phrases": 2,"pre_tag": "","post_tag":
	// ""} }
	Highlight *string `location:"querystring" locationName:"highlight" type:"string"`

	// Enables partial results to be returned if one or more index partitions are
	// unavailable. When your search index is partitioned across multiple search
	// instances, by default Amazon CloudSearch only returns results if every partition
	// can be queried. This means that the failure of a single search instance can
	// result in 5xx (internal server) errors. When you enable partial results,
	// Amazon CloudSearch returns whatever results are available and includes the
	// percentage of documents searched in the search results (percent-searched).
	// This enables you to more gracefully degrade your users' search experience.
	// For example, rather than displaying no results, you could display the partial
	// results and a message indicating that the results might be incomplete due
	// to a temporary system outage.
	Partial *bool `location:"querystring" locationName:"partial" type:"boolean"`

	// Specifies the search criteria for the request. How you specify the search
	// criteria depends on the query parser used for the request and the parser
	// options specified in the queryOptions parameter. By default, the simple query
	// parser is used to process requests. To use the structured, lucene, or dismax
	// query parser, you must also specify the queryParser parameter.
	//
	// For more information about specifying search criteria, see Searching Your
	// Data (http://docs.aws.amazon.com/cloudsearch/latest/developerguide/searching.html)
	// in the Amazon CloudSearch Developer Guide.
	//
	// Query is a required field
	Query *string `location:"querystring" locationName:"q" type:"string" required:"true"`

	// Configures options for the query parser specified in the queryParser parameter.
	// You specify the options in JSON using the following form {"OPTION1":"VALUE1","OPTION2":VALUE2"..."OPTIONN":"VALUEN"}.
	//
	// The options you can configure vary according to which parser you use:
	//
	//    * defaultOperator: The default operator used to combine individual terms
	//    in the search string. For example: defaultOperator: 'or'. For the dismax
	//    parser, you specify a percentage that represents the percentage of terms
	//    in the search string (rounded down) that must match, rather than a default
	//    operator. A value of 0% is the equivalent to OR, and a value of 100% is
	//    equivalent to AND. The percentage must be specified as a value in the
	//    range 0-100 followed by the percent (%) symbol. For example, defaultOperator:
	//    50%. Valid values: and, or, a percentage in the range 0%-100% (dismax).
	//    Default: and (simple, structured, lucene) or 100 (dismax). Valid for:
	//    simple, structured, lucene, and dismax.
	//    * fields: An array of the fields to search when no fields are specified
	//    in a search. If no fields are specified in a search and this option is
	//    not specified, all text and text-array fields are searched. You can specify
	//    a weight for each field to control the relative importance of each field
	//    when Amazon CloudSearch calculates relevance scores. To specify a field
	//    weight, append a caret (^) symbol and the weight to the field name. For
	//    example, to boost the importance of the title field over the description
	//    field you could specify: "fields":["title^5","description"]. Valid values:
	//    The name of any configured field and an optional numeric value greater
	//    than zero. Default: All text and text-array fields. Valid for: simple,
	//    structured, lucene, and dismax.
	//    * operators: An array of the operators or special characters you want
	//    to disable for the simple query parser. If you disable the and, or, or
	//    not operators, the corresponding operators (+, |, -) have no special meaning
	//    and are dropped from the search string. Similarly, disabling prefix disables
	//    the wildcard operator (*) and disabling phrase disables the ability to
	//    search for phrases by enclosing phrases in double quotes. Disabling precedence
	//    disables the ability to control order of precedence using parentheses.
	//    Disabling near disables the ability to use the ~ operator to perform a
	//    sloppy phrase search. Disabling the fuzzy operator disables the ability
	//    to use the ~ operator to perform a fuzzy search. escape disables the ability
	//    to use a backslash (\) to escape special characters within the search
	//    string. Disabling whitespace is an advanced option that prevents the parser
	//    from tokenizing on whitespace, which can be useful for Vietnamese. (It
	//    prevents Vietnamese words from being split incorrectly.) For example,
	//    you could disable all operators other than the phrase operator to support
	//    just simple term and phrase queries: "operators":["and","not","or", "prefix"].
	//    Valid values: and, escape, fuzzy, near, not, or, phrase, precedence, prefix,
	//    whitespace. Default: All operators and special characters are enabled.
	//    Valid for: simple.
	//    * phraseFields: An array of the text or text-array fields you want to
	//    use for phrase searches. When the terms in the search string appear in
	//    close proximity within a field, the field scores higher. You can specify
	//    a weight for each field to boost that score. The phraseSlop option controls
	//    how much the matches can deviate from the search string and still be boosted.
	//    To specify a field weight, append a caret (^) symbol and the weight to
	//    the field name. For example, to boost phrase matches in the title field
	//    over the abstract field, you could specify: "phraseFields":["title^3",
	//    "plot"] Valid values: The name of any text or text-array field and an
	//    optional numeric value greater than zero. Default: No fields. If you don't
	//    specify any fields with phraseFields, proximity scoring is disabled even
	//    if phraseSlop is specified. Valid for: dismax.
	//    * phraseSlop: An integer value that specifies how much matches can deviate
	//    from the search phrase and still be boosted according to the weights specified
	//    in the phraseFields option; for example, phraseSlop: 2. You must also
	//    specify phraseFields to enable proximity scoring. Valid values: positive
	//    integers. Default: 0. Valid for: dismax.
	//    * explicitPhraseSlop: An integer value that specifies how much a match
	//    can deviate from the search phrase when the phrase is enclosed in double
	//    quotes in the search string. (Phrases that exceed this proximity distance
	//    are not considered a match.) For example, to specify a slop of three for
	//    dismax phrase queries, you would specify "explicitPhraseSlop":3. Valid
	//    values: positive integers. Default: 0. Valid for: dismax.
	//    * tieBreaker: When a term in the search string is found in a document's
	//    field, a score is calculated for that field based on how common the word
	//    is in that field compared to other documents. If the term occurs in multiple
	//    fields within a document, by default only the highest scoring field contributes
	//    to the document's overall score. You can specify a tieBreaker value to
	//    enable the matches in lower-scoring fields to contribute to the document's
	//    score. That way, if two documents have the same max field score for a
	//    particular term, the score for the document that has matches in more fields
	//    will be higher. The formula for calculating the score with a tieBreaker
	//    is (max field score) + (tieBreaker) * (sum of the scores for the rest
	//    of the matching fields). Set tieBreaker to 0 to disregard all but the
	//    highest scoring field (pure max): "tieBreaker":0. Set to 1 to sum the
	//    scores from all fields (pure sum): "tieBreaker":1. Valid values: 0.0 to
	//    1.0. Default: 0.0. Valid for: dismax.
	QueryOptions *string `location:"querystring" locationName:"q.options" type:"string"`

	// Specifies which query parser to use to process the request. If queryParser
	// is not specified, Amazon CloudSearch uses the simple query parser.
	//
	// Amazon CloudSearch supports four query parsers:
	//
	//    * simple: perform simple searches of text and text-array fields. By default,
	//    the simple query parser searches all text and text-array fields. You can
	//    specify which fields to search by with the queryOptions parameter. If
	//    you prefix a search term with a plus sign (+) documents must contain the
	//    term to be considered a match. (This is the default, unless you configure
	//    the default operator with the queryOptions parameter.) You can use the
	//    - (NOT), | (OR), and * (wildcard) operators to exclude particular terms,
	//    find results that match any of the specified terms, or search for a prefix.
	//    To search for a phrase rather than individual terms, enclose the phrase
	//    in double quotes. For more information, see Searching for Text (http://docs.aws.amazon.com/cloudsearch/latest/developerguide/searching-text.html)
	//    in the Amazon CloudSearch Developer Guide.
	//    * structured: perform advanced searches by combining multiple expressions
	//    to define the search criteria. You can also search within particular fields,
	//    search for values and ranges of values, and use advanced options such
	//    as term boosting, matchall, and near. For more information, see Constructing
	//    Compound Queries (http://docs.aws.amazon.com/cloudsearch/latest/developerguide/searching-compound-queries.html)
	//    in the Amazon CloudSearch Developer Guide.
	//    * lucene: search using the Apache Lucene query parser syntax. For more
	//    information, see Apache Lucene Query Parser Syntax (http://lucene.apache.org/core/4_6_0/queryparser/org/apache/lucene/queryparser/classic/package-summary.html#package_description).
	//
	//    * dismax: search using the simplified subset of the Apache Lucene query
	//    parser syntax defined by the DisMax query parser. For more information,
	//    see DisMax Query Parser Syntax (http://wiki.apache.org/solr/DisMaxQParserPlugin#Query_Syntax).
	//
	QueryParser *string `location:"querystring" locationName:"q.parser" type:"string" enum:"QueryParser"`

	// Specifies the field and expression values to include in the response. Multiple
	// fields or expressions are specified as a comma-separated list. By default,
	// a search response includes all return enabled fields (_all_fields). To return
	// only the document IDs for the matching documents, specify _no_fields. To
	// retrieve the relevance score calculated for each document, specify _score.

	// in the domain configuration. Array type fields cannot be used for sorting.
	// If no sort parameter is specified, results are sorted by their default relevance
	// scores in descending order: _score desc. You can also sort by document ID
	// (_id asc) and version (_version desc).
