Bool(Func<BoolQueryDescriptor<T>, IBoolQuery>)
A query that matches documents matching boolean combinations of other queries. The bool query maps to
Lucene BooleanQuery.
It is built using one or more boolean clauses, each clause with a typed occurrence
Declaration
public QueryContainer Bool(Func<BoolQueryDescriptor<T>, IBoolQuery> selector)
Parameters
Returns

Boosting(Func<BoostingQueryDescriptor<T>, IBoostingQuery>)
A query that can be used to effectively demote results that match a given query.
Unlike the "must_not" clause in bool query, this still selects documents that contain
undesirable terms, but reduces their overall score.
Declaration
public QueryContainer Boosting(Func<BoostingQueryDescriptor<T>, IBoostingQuery> selector)
Parameters
Returns

Conditionless(Func<ConditionlessQueryDescriptor<T>, IConditionlessQuery>)
A thin wrapper allowing fined grained control what should happen if a query is conditionless
if you need to fallback to something other than a match_all query
Declaration
public QueryContainer Conditionless(Func<ConditionlessQueryDescriptor<T>, IConditionlessQuery> selector)
Parameters

ConstantScore(Func<ConstantScoreQueryDescriptor<T>, IConstantScoreQuery>)

for every document in the filter. Maps to Lucene ConstantScoreQuery.

DisMax(Func<DisMaxQueryDescriptor<T>, IDisMaxQuery>)

with the maximum score for that document as produced by any subquery, plus a tie breaking increment for
any additional matching subqueries.

DistanceFeature(Func<DistanceFeatureQueryDescriptor<T>, IDistanceFeatureQuery>)
Boosts the relevance score of documents closer to a provided origin date or point. For example, you can use this query to give
more weight to documents closer to a certain date or location.
You can use the distance_feature query to find the nearest neighbors to a location. You can also use the query in a bool
search’s should filter to add boosted relevance scores to the bool query’s scores.

FunctionScore(Func<FunctionScoreQueryDescriptor<T>, IFunctionScoreQuery>)
The function_score query allows you to modify the score of documents that are retrieved by a query.
This can be useful if, for example, a score function is computationally expensive and it is
sufficient to compute the score on a filtered set of documents.

Fuzzy(Func<FuzzyQueryDescriptor<T>, IFuzzyQuery>)

every term will be enumerated and cause an edit score calculation or max_expansions is not set.

Intervals(Func<IntervalsQueryDescriptor<T>, IIntervalsQuery>)
Allows fine-grained control over the order and proximity of matching terms.

MultiMatch(Func<MultiMatchQueryDescriptor<T>, IMultiMatchQuery>)
The multi_match query builds further on top of the match query by allowing multiple fields to be specified.

relatively more expressive query by using multiple match queries within a bool query.

Nested(Func<NestedQueryDescriptor<T>, INestedQuery>)

RankFeature(Func<RankFeatureQueryDescriptor<T>, IRankFeatureQuery>)
A query that only works on rank_feature fields and rank_features fields. Its goal is to boost the score of documents
based on the values of numeric features. It is typically put in a should clause of a bool query so that its score
is added to the score of the query.
Compared to using function_score or other ways to modify the score, this query has the benefit of being able to efficiently
skip non-competitive hits when track_total_hits is not set to true. Speedups may be spectacular.

public QueryContainer RankFeature(Func<RankFeatureQueryDescriptor<T>, IRankFeatureQuery> selector)
