Method Detail

newMatchAllQuery

public static org.apache.lucene.search.Query newMatchAllQuery()

newMatchNoDocsQuery

public static org.apache.lucene.search.Query newMatchNoDocsQuery(java.lang.String reason)

Return a query that matches no document.

newUnmappedFieldQuery

public static org.apache.lucene.search.Query newUnmappedFieldQuery(java.lang.String field)

newLenientFieldQuery

public static org.apache.lucene.search.Query newLenientFieldQuery(java.lang.String field,
                                                                  java.lang.RuntimeException e)

newNestedFilter

public static org.apache.lucene.search.Query newNestedFilter()

newNonNestedFilter

public static org.apache.lucene.search.Query newNonNestedFilter(Version indexVersionCreated)

Creates a new non-nested docs query

Parameters:

indexVersionCreated - the index version created since newer indices can identify a parent field more efficiently

filtered

public static org.apache.lucene.search.BooleanQuery filtered(@Nullable
                                                             org.apache.lucene.search.Query query,

not

public static org.apache.lucene.search.Query not(org.apache.lucene.search.Query q)

Return a query that matches all documents but those that match the given query.

fixNegativeQueryIfNeeded

public static org.apache.lucene.search.Query fixNegativeQueryIfNeeded(org.apache.lucene.search.Query q)

applyMinimumShouldMatch
