type ExistsQuery 

type ExistsQuery struct {
	// contains filtered or unexported fields

ExistsQuery is a query that only matches on documents that the field has a value in them.

For more details, see: https://www.elastic.co/guide/en/elasticsearch/reference/6.8/query-dsl-exists-query.html

func NewExistsQuery(name string) *ExistsQuery

NewExistsQuery creates and initializes a new exists query.

func (*ExistsQuery) QueryName 

func (q *ExistsQuery) QueryName(queryName string) *ExistsQuery

QueryName sets the query name for the filter that can be used when searching for matched queries per hit.

func (*ExistsQuery) Source 

func (q *ExistsQuery) Source() (interface{}, error)

Source returns the JSON serializable content for this query.

type FieldSort 

type FieldSort struct {
	Sorter
	// contains filtered or unexported fields
}

FieldSort sorts by a given field.

func NewFieldSort 

func NewFieldSort(fieldName string) *FieldSort

NewFieldSort creates a new FieldSort.

func (*FieldSort) Asc 

func (s *FieldSort) Asc() *FieldSort

Asc sets ascending sort order.

func (*FieldSort) Desc 

func (s *FieldSort) Desc() *FieldSort

Desc sets descending sort order.

func (*FieldSort) FieldName 

func (s *FieldSort) FieldName(fieldName string) *FieldSort

FieldName specifies the name of the field to be used for sorting.

func (*FieldSort) Order 

func (s *FieldSort) Order(ascending bool) *FieldSort

Order defines whether sorting ascending (default) or descending.

func (*FieldSort) Source 

func (s *FieldSort) Source() (interface{}, error)

Source returns the JSON-serializable data.

type MatchQuery 

type MatchQuery struct {
	// contains filtered or unexported fields
}

MatchQuery is a family of queries that accepts text/numerics/dates, analyzes them, and constructs a query.

To create a new MatchQuery, use NewMatchQuery. To create specific types of queries, e.g. a match_phrase query, use NewMatchPhrQuery(...).Type("phrase"), or use one of the shortcuts e.g. NewMatchPhraseQuery(...).

For more details, see https://www.elastic.co/guide/en/elasticsearch/reference/7.0/query-dsl-match-query.html

func NewMatchQuery 

func NewMatchQuery(name string, text interface{}) *MatchQuery

NewMatchQuery creates and initializes a new MatchQuery.

func (*MatchQuery) Analyzer 

func (q *MatchQuery) Analyzer(analyzer string) *MatchQuery

Analyzer explicitly sets the analyzer to use. It defaults to use explicit mapping config for the field, or, if not set, the default search analyzer.

func (*MatchQuery) Boost 

func (q *MatchQuery) Boost(boost float64) *MatchQuery

Boost sets the boost to apply to this query.

func (*MatchQuery) CutoffFrequency 

func (q *MatchQuery) CutoffFrequency(cutoff float64) *MatchQuery

CutoffFrequency can be a value in [0..1] (or an absolute number >=1). It represents the maximum treshold of a terms document frequency to be considered a low frequency term.

func (*MatchQuery) Fuzziness 

func (q *MatchQuery) Fuzziness(fuzziness string) *MatchQuery

Fuzziness sets the fuzziness when evaluated to a fuzzy query type. Defaults to "AUTO".

func (*MatchQuery) FuzzyRewrite 

func (q *MatchQuery) FuzzyRewrite(fuzzyRewrite string) *MatchQuery

FuzzyRewrite sets the fuzzy_rewrite parameter controlling how the fuzzy query will get rewritten.

func (*MatchQuery) FuzzyTranspositions 

func (q *MatchQuery) FuzzyTranspositions(fuzzyTranspositions bool) *MatchQuery

FuzzyTranspositions sets whether transpositions are supported in fuzzy queries.

The default metric used by fuzzy queries to determine a match is the Damerau-Levenshtein distance formula which supports transpositions. Setting transposition to false will * switch to classic Levenshtein distance. * If not set, Damerau-Levenshtein distance metric will be used.

func (*MatchQuery) Lenient 

func (q *MatchQuery) Lenient(lenient bool) *MatchQuery

Lenient specifies whether format based failures will be ignored.

func (*MatchQuery) MaxExpansions 

func (q *MatchQuery) MaxExpansions(maxExpansions int) *MatchQuery

MaxExpansions is used with fuzzy or prefix type queries. It specifies the number of term expansions to use. It defaults to unbounded so that its recommended to set it to a reasonable value for faster execution.

func (*MatchQuery) MinimumShouldMatch 

func (q *MatchQuery) MinimumShouldMatch(minimumShouldMatch string) *MatchQuery

MinimumShouldMatch sets the optional minimumShouldMatch value to apply to the query.

func (*MatchQuery) Operator 

func (q *MatchQuery) Operator(operator string) *MatchQuery

Operator sets the operator to use when using a boolean query. Can be "AND" or "OR" (default).

func (*MatchQuery) PrefixLength 

func (q *MatchQuery) PrefixLength(prefixLength int) *MatchQuery

func (q *MatchQuery) QueryName(queryName string) *MatchQuery

QueryName sets the query name for the filter that can be used when searching for matched filters per hit.

func (*MatchQuery) Source 

func (q *MatchQuery) Source() (interface{}, error)

Source returns JSON for the function score query.

func (*MatchQuery) ZeroTermsQuery 

func (q *MatchQuery) ZeroTermsQuery(zeroTermsQuery string) *MatchQuery

ZeroTermsQuery can be "all" or "none".

type Query 

type Query interface {
	// Source returns the JSON-serializable query request.
	Source() (interface{}, error)
}

type RangeQuery 

type RangeQuery struct {
	// contains filtered or unexported fields
}

RangeQuery matches documents with fields that have terms within a certain range.

NewRangeQuery creates and initializes a new RangeQuery.

func (*RangeQuery) From 

func (q *RangeQuery) From(from interface{}) *RangeQuery
