List<QueryBuilder>	filter()	Gets the queries that must appear in the matching documents but don't contribute to scoring
BoolQueryBuilder	filter(QueryBuilder queryBuilder)	Adds a query that must appear in the matching documents but will not contribute to scoring.
static BoolQueryBuilder	fromXContent(XContentParser parser)

boolean	hasClauses()	Returns true iff this query builder has at least one should, must, must not or filter clause.
String	minimumShouldMatch()
BoolQueryBuilder	minimumShouldMatch(int minimumShouldMatch)	Specifies a minimum number of the optional (should) boolean clauses which must be satisfied.
BoolQueryBuilder	minimumShouldMatch(String minimumShouldMatch)	Sets the minimum should match parameter using the special syntax (for example, supporting percentage).

BoolQueryBuilder	must(QueryBuilder queryBuilder)	Adds a query that must appear in the matching documents and will contribute to scoring.
List<QueryBuilder>	mustNot()	Gets the queries that must not appear in the matching documents.
BoolQueryBuilder	mustNot(QueryBuilder queryBuilder)	Adds a query that must not appear in the matching documents.
List<QueryBuilder>	should()	Gets the list of clauses that should be matched by the returned documents.
BoolQueryBuilder	should(QueryBuilder queryBuilder)	Adds a clause that should be matched by the returned documents.

Constructor Detail

BoolQueryBuilder

public BoolQueryBuilder()

Build an empty bool query.

BoolQueryBuilder

public BoolQueryBuilder(StreamInput in)
                 throws IOException

Read from a stream.

Throws:

IOException

Method Detail

doWriteTo

protected void doWriteTo(StreamOutput out)
                  throws IOException

Specified by:

doWriteTo in class AbstractQueryBuilder<BoolQueryBuilder>

Throws:

IOException

must

public BoolQueryBuilder must(QueryBuilder queryBuilder)

Adds a query that must appear in the matching documents and will contribute to scoring. No null value allowed.

must

public List<QueryBuilder> must()

Gets the queries that must appear in the matching documents.

filter

public BoolQueryBuilder filter(QueryBuilder queryBuilder)

Adds a query that must appear in the matching documents but will not contribute to scoring. No null value allowed.

filter

public List<QueryBuilder> filter()

Gets the queries that must appear in the matching documents but don't contribute to scoring

mustNot

public BoolQueryBuilder mustNot(QueryBuilder queryBuilder)

Adds a query that must not appear in the matching documents. No null value allowed.

mustNot

public List<QueryBuilder> mustNot()

Gets the queries that must not appear in the matching documents.

should

public BoolQueryBuilder should(QueryBuilder queryBuilder)

Adds a clause that should be matched by the returned documents. For a boolean query with no MUST clauses one or more SHOULD clauses must match a document for the BooleanQuery to match. No null value allowed.

See Also:

minimumShouldMatch(int)

should

public List<QueryBuilder> should()

Gets the list of clauses that should be matched by the returned documents.

See Also:

should(QueryBuilder), minimumShouldMatch(int)

minimumShouldMatch

public String minimumShouldMatch()

Returns:

the string representation of the minimumShouldMatch settings for this query

minimumShouldMatch

public BoolQueryBuilder minimumShouldMatch(String minimumShouldMatch)

Sets the minimum should match parameter using the special syntax (for example, supporting percentage).

See Also:

minimumShouldMatch(int)

minimumShouldMatch

public BoolQueryBuilder minimumShouldMatch(int minimumShouldMatch)

Specifies a minimum number of the optional (should) boolean clauses which must be satisfied.

By default no optional clauses are necessary for a match (unless there are no required clauses). If this method is used, then the specified number of clauses is required.

Use of this method is totally independent of specifying that any specific clauses are required (or prohibited). This number will only be compared against the number of matching optional clauses.

Parameters:

minimumShouldMatch - the number of optional clauses that must match

hasClauses

public boolean hasClauses()

Returns true iff this query builder has at least one should, must, must not or filter clause. Otherwise false.

adjustPureNegative

public BoolQueryBuilder adjustPureNegative(boolean adjustPureNegative)

If a boolean query contains only negative ("must not") clauses should the BooleanQuery be enhanced with a MatchAllDocsQuery in order to act as a pure exclude. The default is true.

adjustPureNegative

public boolean adjustPureNegative()

Returns:

the setting for the adjust_pure_negative setting in this query

doXContent

protected void doXContent(XContentBuilder builder,
                          ToXContent.Params params)
                   throws IOException

Specified by:

doXContent in class AbstractQueryBuilder<BoolQueryBuilder>

Throws:

IOException

fromXContent

public static BoolQueryBuilder fromXContent(XContentParser parser)
                                     throws IOException,

extractInnerHitBuilders

protected void extractInnerHitBuilders(Map<String,InnerHitContextBuilder> innerHits)
