public static Query newMatchNoDocsQuery(String reason)

Return a query that matches no document.

newUnmappedFieldQuery

public static Query newUnmappedFieldQuery(String field)

newUnmappedFieldsQuery

public static Query newUnmappedFieldsQuery(Collection<String> fields)

newLenientFieldQuery

public static Query newLenientFieldQuery(String field,
                                         RuntimeException e)

newNestedFilter

public static Query newNestedFilter()

newNonNestedFilter

public static 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 BooleanQuery filtered(@Nullable
                                    Query query,
                                    @Nullable
                                    Query filter)

not

public static Query not(Query q)

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

fixNegativeQueryIfNeeded

public static Query fixNegativeQueryIfNeeded(Query q)

applyMinimumShouldMatch

public static Query applyMinimumShouldMatch(BooleanQuery query,
                                            @Nullable
                                            String minimumShouldMatch)

maybeApplyMinimumShouldMatch
