Class StringFieldType

org.elasticsearch.index.mapper.MappedFieldType

org.elasticsearch.index.mapper.SimpleMappedFieldType

org.elasticsearch.index.mapper.StringFieldType

Direct Known Subclasses:

IgnoredFieldMapper.IgnoredFieldType, KeywordFieldMapper.KeywordFieldType, TextFieldMapper.TextFieldType, TypeFieldMapper.TypeFieldType

public abstract class StringFieldType
extends SimpleMappedFieldType

Base class for MappedFieldType implementations that use the same representation for internal index terms as the external representation so that partial matching queries such as prefix, wildcard and fuzzy queries can be implemented.

StringFieldType

public StringFieldType(java.lang.String name, boolean isSearchable, boolean hasDocValues, TextSearchInfo textSearchInfo, java.util.Map<java.lang.String,java.lang.String> meta)

Method Details

fuzzyQuery

public org.apache.lucene.search.Query fuzzyQuery(java.lang.Object value, Fuzziness fuzziness, int prefixLength, int maxExpansions, boolean transpositions, QueryShardContext context)

Overrides:

fuzzyQuery in class MappedFieldType

prefixQuery

public org.apache.lucene.search.Query prefixQuery(java.lang.String value, org.apache.lucene.search.MultiTermQuery.RewriteMethod method, QueryShardContext context)

Overrides:

prefixQuery in class MappedFieldType

normalizeWildcardPattern

public static final java.lang.String normalizeWildcardPattern(java.lang.String fieldname, java.lang.String value, org.apache.lucene.analysis.Analyzer normalizer)

wildcardQuery

public org.apache.lucene.search.Query wildcardQuery(java.lang.String value, org.apache.lucene.search.MultiTermQuery.RewriteMethod method, QueryShardContext context)

Overrides:

wildcardQuery in class MappedFieldType

regexpQuery

public org.apache.lucene.search.Query regexpQuery(java.lang.String value, int flags, int maxDeterminizedStates, org.apache.lucene.search.MultiTermQuery.RewriteMethod method, QueryShardContext context)

Overrides:

regexpQuery in class MappedFieldType

rangeQuery

public org.apache.lucene.search.Query rangeQuery(java.lang.Object lowerTerm, java.lang.Object upperTerm, boolean includeLower, boolean includeUpper, QueryShardContext context)

Description copied from class: SimpleMappedFieldType

Same as SimpleMappedFieldType.rangeQuery(Object, Object, boolean, boolean, ShapeRelation, ZoneId, DateMathParser, QueryShardContext) but without the trouble of relations or date-specific options.

Overrides:

rangeQuery in class SimpleMappedFieldType

indexedValueForSearch

protected org.apache.lucene.util.BytesRef indexedValueForSearch(java.lang.Object value)

Returns the indexed value used to construct search "values". This method is used for the default implementations of most query factory methods such as MappedFieldType.termQuery(java.lang.Object, org.elasticsearch.index.query.QueryShardContext).

termQuery

public org.apache.lucene.search.Query termQuery(java.lang.Object value, QueryShardContext context)

Description copied from class: MappedFieldType

Generates a query that will only match documents that contain the given value. The default implementation returns a TermQuery over the value bytes, boosted by MappedFieldType.boost().

Specified by:

termQuery in class MappedFieldType

termsQuery

public org.apache.lucene.search.Query termsQuery(java.util.List<?> values, QueryShardContext context)

Description copied from class: MappedFieldType

Build a constant-scoring query that matches all values. The default implementation uses a ConstantScoreQuery around a BooleanQuery whose BooleanClause.Occur.SHOULD clauses are generated with MappedFieldType.termQuery(java.lang.Object, org.elasticsearch.index.query.QueryShardContext).

Overrides:

termsQuery in class MappedFieldType
