Class MatchBoolPrefixQueryBuilder

java.lang.Object

org.elasticsearch.index.query.AbstractQueryBuilder<MatchBoolPrefixQueryBuilder>

org.elasticsearch.index.query.MatchBoolPrefixQueryBuilder

All Implemented Interfaces:

NamedWriteable, Writeable, ToXContent, ToXContentObject, QueryBuilder, Rewriteable<QueryBuilder>

public class MatchBoolPrefixQueryBuilder
extends AbstractQueryBuilder<MatchBoolPrefixQueryBuilder>

The boolean prefix query analyzes the input text and creates a boolean query containing a Term query for each term, except for the last term, which is used to create a prefix query

Constructor Detail

MatchBoolPrefixQueryBuilder

public MatchBoolPrefixQueryBuilder(String fieldName,
                                   Object value)

MatchBoolPrefixQueryBuilder

public MatchBoolPrefixQueryBuilder(StreamInput in)
                            throws IOException

Throws:

IOException

Method Detail

doWriteTo

protected void doWriteTo(StreamOutput out)
                  throws IOException

Specified by:

doWriteTo in class AbstractQueryBuilder<MatchBoolPrefixQueryBuilder>

Throws:

IOException

fieldName

public String fieldName()

Returns the field name used in this query.

value

public Object value()

Returns the value used in this query.

analyzer

public String analyzer()

Get the analyzer to use, if previously set, otherwise null

analyzer

public MatchBoolPrefixQueryBuilder analyzer(String analyzer)

Explicitly set the analyzer to use. Defaults to use explicit mapping config for the field, or, if not set, the default search analyzer.

operator

public MatchBoolPrefixQueryBuilder operator(Operator operator)

Sets the operator to use when using a boolean query. Defaults to OR.

operator

public Operator operator()

Returns the operator to use in a boolean query.

minimumShouldMatch

public MatchBoolPrefixQueryBuilder minimumShouldMatch(String minimumShouldMatch)

Sets optional minimumShouldMatch value to apply to the query

minimumShouldMatch

public String minimumShouldMatch()

Gets the minimumShouldMatch value

fuzziness

public MatchBoolPrefixQueryBuilder fuzziness(Object fuzziness)

Sets the fuzziness used when evaluated to a fuzzy query type. Defaults to "AUTO".

fuzziness

public Fuzziness fuzziness()

Gets the fuzziness used when evaluated to a fuzzy query type.

prefixLength

public MatchBoolPrefixQueryBuilder prefixLength(int prefixLength)

Sets the length of a length of common (non-fuzzy) prefix for fuzzy match queries

Parameters:

prefixLength - non-negative length of prefix

Throws:

IllegalArgumentException - in case the prefix is negative

prefixLength

public int prefixLength()

Gets the length of a length of common (non-fuzzy) prefix for fuzzy match queries

maxExpansions

public MatchBoolPrefixQueryBuilder maxExpansions(int maxExpansions)

When using fuzzy or prefix type query, the number of term expansions to use.

maxExpansions

public int maxExpansions()

Get the (optional) number of term expansions when using fuzzy or prefix type query.

fuzzyTranspositions

public MatchBoolPrefixQueryBuilder fuzzyTranspositions(boolean 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.

fuzzyTranspositions

public boolean fuzzyTranspositions()

Gets the fuzzy query transposition setting.

fuzzyRewrite

public MatchBoolPrefixQueryBuilder fuzzyRewrite(String fuzzyRewrite)

Sets the fuzzy_rewrite parameter controlling how the fuzzy query will get rewritten

fuzzyRewrite

public String fuzzyRewrite()

Get the fuzzy_rewrite parameter

See Also:

fuzzyRewrite(String)

Specified by:

doXContent in class AbstractQueryBuilder<MatchBoolPrefixQueryBuilder>

Throws:

IOException

fromXContent

public static MatchBoolPrefixQueryBuilder fromXContent(XContentParser parser)
                                                throws IOException

Throws:

IOException

Indicates whether some other QueryBuilder object of the same type is "equal to" this one.

Specified by:

doEquals in class AbstractQueryBuilder<MatchBoolPrefixQueryBuilder>

doHashCode

protected int doHashCode()

Specified by:

doHashCode in class AbstractQueryBuilder<MatchBoolPrefixQueryBuilder>

getWriteableName
