Constructor Details

PrefixQueryBuilder

public PrefixQueryBuilder(String fieldName,
 String value)

A Query that matches documents containing terms with a specified prefix.

Parameters:

fieldName - The name of the field

value - The prefix query

PrefixQueryBuilder

public PrefixQueryBuilder(StreamInput in)
                   throws IOException

Read from a stream.

Throws:

IOException

Method Details

doWriteTo

protected void doWriteTo(StreamOutput out)
                  throws IOException

Specified by:

doWriteTo in class AbstractQueryBuilder<PrefixQueryBuilder>

Throws:

IOException

fieldName

public String fieldName()

Description copied from interface: MultiTermQueryBuilder

Get the field name for this query.

Specified by:

fieldName in interface MultiTermQueryBuilder

value

public String value()

caseInsensitive

public PrefixQueryBuilder caseInsensitive(boolean caseInsensitive)

caseInsensitive

public boolean caseInsensitive()

rewrite

public PrefixQueryBuilder rewrite(String rewrite)

rewrite

public String rewrite()

doXContent

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

Specified by:

doXContent in class AbstractQueryBuilder<PrefixQueryBuilder>

Throws:

IOException

fromXContent

public static PrefixQueryBuilder fromXContent(XContentParser parser)
                                       throws IOException

Throws:

IOException

getWriteableName

public String getWriteableName()

Description copied from interface: VersionedNamedWriteable

Returns the name of the writeable object

Specified by:

getWriteableName in interface NamedWriteable

Specified by:

getWriteableName in interface VersionedNamedWriteable

doIndexMetadataRewrite

protected QueryBuilder doIndexMetadataRewrite(QueryRewriteContext context)
                                       throws IOException

Description copied from class: AbstractQueryBuilder

Optional rewrite logic that only needs access to index level metadata and services (e.g. index settings and mappings) on the data node, but not the shard / Lucene index. The can_match phase can use this logic to early terminate a search without doing any search related i/o.

Overrides:

doIndexMetadataRewrite in class AbstractQueryBuilder<PrefixQueryBuilder>

Parameters:

context - an QueryRewriteContext instance that has access the mappings and other index metadata

Returns:

A QueryBuilder representing the rewritten query, that could be used to determine whether this query yields result.

Throws:

IOException

doToQuery

protected org.apache.lucene.search.Query doToQuery(SearchExecutionContext context)
                                            throws IOException

Specified by:

doToQuery in class AbstractQueryBuilder<PrefixQueryBuilder>

Throws:

IOException

doHashCode

protected final int doHashCode()

Specified by:

doHashCode in class AbstractQueryBuilder<PrefixQueryBuilder>

doEquals

protected boolean doEquals(PrefixQueryBuilder other)

Description copied from class: AbstractQueryBuilder

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

Specified by:

doEquals in class AbstractQueryBuilder<PrefixQueryBuilder>

getMinimalSupportedVersion

public TransportVersion getMinimalSupportedVersion()

Description copied from interface: VersionedNamedWriteable

The minimal version of the recipient this object can be sent to

Specified by:

getMinimalSupportedVersion in interface VersionedNamedWriteable
