Method Details
-
isSearchable
public boolean isSearchable()Description copied from class:MappedFieldType
Returns true if the field is searchable.- Overrides:
isSearchable
in classMappedFieldType
-
termQuery
Description copied from class:MappedFieldType
Generates a query that will only match documents that contain the given value. The default implementation returns aTermQuery
over the value bytes- Overrides:
termQuery
in classTermBasedFieldType
-
termsQuery
public org.apache.lucene.search.Query termsQuery(Collection<?> values, SearchExecutionContext context) Description copied from class:MappedFieldType
Build a constant-scoring query that matches all values. The default implementation uses aConstantScoreQuery
around aBooleanQuery
whoseBooleanClause.Occur.SHOULD
clauses are generated withMappedFieldType.termQuery(java.lang.Object, org.elasticsearch.index.query.SearchExecutionContext)
.- Overrides:
termsQuery
in classTermBasedFieldType
-
rangeQuery
public org.apache.lucene.search.Query rangeQuery(Object lowerTerm, Object upperTerm, boolean includeLower, boolean includeUpper, SearchExecutionContext context) Description copied from class:SimpleMappedFieldType
Same asSimpleMappedFieldType.rangeQuery(Object, Object, boolean, boolean, ShapeRelation, ZoneId, DateMathParser, SearchExecutionContext)
but without the trouble of relations or date-specific options.- Overrides:
rangeQuery
in classStringFieldType
-
fuzzyQuery
public org.apache.lucene.search.Query fuzzyQuery(Object value, Fuzziness fuzziness, int prefixLength, int maxExpansions, boolean transpositions, SearchExecutionContext context, @Nullable org.apache.lucene.search.MultiTermQuery.RewriteMethod rewriteMethod) - Overrides:
fuzzyQuery
in classStringFieldType
-
prefixQuery
public org.apache.lucene.search.Query prefixQuery(String value, org.apache.lucene.search.MultiTermQuery.RewriteMethod method, boolean caseInsensitive, SearchExecutionContext context) - Overrides:
prefixQuery
in classStringFieldType
-
termQueryCaseInsensitive
public org.apache.lucene.search.Query termQueryCaseInsensitive(Object value, SearchExecutionContext context) - Overrides:
termQueryCaseInsensitive
in classTermBasedFieldType
-
getTerms
public org.apache.lucene.index.TermsEnum getTerms(org.apache.lucene.index.IndexReader reader, String prefix, boolean caseInsensitive, String searchAfter) throws IOException Description copied from class:MappedFieldType
This method is used to support auto-complete services and implementations are expected to find terms beginning with the provided string very quickly. If fields cannot look up matching terms quickly they should return null. The returned TermEnum should implement next(), term() and doc_freq() methods but postings etc are not required.- Overrides:
getTerms
in classMappedFieldType
- Parameters:
reader
- an index readerprefix
- the partially complete word the user has typed (can be empty)caseInsensitive
- if prefix matches should be case insensitivesearchAfter
- - usually null. If supplied the TermsEnum result must be positioned after the provided term (used for pagination)- Returns:
- null or an enumeration of matching terms
- Throws:
IOException
- Errors accessing data
-
typeName
Description copied from class:MappedFieldType
Returns the name of this type, as would be specified in mapping properties- Specified by:
typeName
in classMappedFieldType
-
eagerGlobalOrdinals
public boolean eagerGlobalOrdinals()- Overrides:
eagerGlobalOrdinals
in classMappedFieldType
- Returns:
- if this field type should load global ordinals eagerly
-
blockLoader
Description copied from class:MappedFieldType
Returns a loader for ESQL ornull
if the field doesn't support ESQL.- Overrides:
blockLoader
in classMappedFieldType
-
fielddataBuilder
Description copied from class:MappedFieldType
Return a fielddata builder for this field- Overrides:
fielddataBuilder
in classMappedFieldType
- Parameters:
fieldDataContext
- the context for the fielddata
-
valueFetcher
Description copied from class:MappedFieldType
Create a helper class to fetch field values during theFetchFieldsPhase
. New field types must implement this method in order to support the search 'fields' option. Except for metadata fields, field types should not throwUnsupportedOperationException
since this could cause a search retrieving multiple fields (like "fields": ["*"]) to fail.- Specified by:
valueFetcher
in classMappedFieldType
-
valueForDisplay
Description copied from class:MappedFieldType
Given a value that comes from the stored fields API, convert it to the expected type. For instance a date field would store dates as longs and format it back to a string in this method.- Overrides:
valueForDisplay
in classMappedFieldType
-
indexedValueForSearch
Description copied from class:TermBasedFieldType
Returns the indexed value used to construct search "values". This method is used for the default implementations of most query factory methods such asTermBasedFieldType.termQuery(java.lang.Object, org.elasticsearch.index.query.SearchExecutionContext)
.- Overrides:
indexedValueForSearch
in classTermBasedFieldType
-
wildcardQuery
public org.apache.lucene.search.Query wildcardQuery(String value, org.apache.lucene.search.MultiTermQuery.RewriteMethod method, boolean caseInsensitive, SearchExecutionContext context) Wildcard queries on keyword fields use the normalizer of the underlying field, regardless of their case sensitivity option- Overrides:
wildcardQuery
in classStringFieldType
-
normalizedWildcardQuery
public org.apache.lucene.search.Query normalizedWildcardQuery(String value, org.apache.lucene.search.MultiTermQuery.RewriteMethod method, SearchExecutionContext context) - Overrides:
normalizedWildcardQuery
in classStringFieldType
-
regexpQuery
public org.apache.lucene.search.Query regexpQuery(String value, int syntaxFlags, int matchFlags, int maxDeterminizedStates, org.apache.lucene.search.MultiTermQuery.RewriteMethod method, SearchExecutionContext context) - Overrides:
regexpQuery
in classStringFieldType
-
collapseType
Description copied from class:MappedFieldType
Returns the collapse type of the field CollapseType.NONE means the field can'be used for collapsing.- Overrides:
collapseType
in classMappedFieldType
- Returns:
- collapse type of the field
-
ignoreAbove
public int ignoreAbove()Values that have more chars than the return value of this method will be skipped at parsing time. -
isDimension
public boolean isDimension()- Overrides:
isDimension
in classMappedFieldType
- Returns:
- true if field has been marked as a dimension field
-
validateMatchedRoutingPath
Description copied from class:MappedFieldType
Validate that this field can be the target ofIndexMetadata.INDEX_ROUTING_PATH
