        private MultiPhraseQuery​(java.lang.String field,
                                 Term[][] termArrays,
                                 int[] positions,

    • Method Detail

      • getTermArrays

        public Term[][] getTermArrays()
        Returns the arrays of arrays of terms in the multi-phrase. Do not modify!
      • getPositions

        public int[] getPositions()
        Returns the relative positions of terms in this phrase. Do not modify!
      • rewrite

        public Query rewrite​(IndexSearcher indexSearcher)
                      throws java.io.IOException
        Description copied from class: Query
        Expert: called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys.

        Callers are expected to call rewrite multiple times if necessary, until the rewritten query is the same as the original query.

        The rewrite process may be able to make use of IndexSearcher's executor and be executed in parallel if the executor is provided.

        However, if any of the intermediary queries do not satisfy the new API, parallel rewrite is not possible for any subsequent sub-queries. To take advantage of this API, the entire query tree must override this method.

        Overrides:
        rewrite in class Query
        Throws:
        java.io.IOException

        IndexSearcher.rewrite(Query)
      • visit

        public void visit​(QueryVisitor visitor)
        Description copied from class: Query
        Recurse through the query tree, visiting any child queries.
        Specified by:
        visit in class Query
        Parameters:
        visitor - a QueryVisitor to be called by each query in the tree
      • createWeight

        public Weight createWeight​(IndexSearcher searcher,
                                   ScoreMode scoreMode,
                                   float boost)
                            throws java.io.IOException
        Description copied from class: Query
        Expert: Constructs an appropriate Weight implementation for this query.

        Only implemented by primitive queries, which re-write to themselves.

        Overrides:
        createWeight in class Query
        scoreMode - How the produced scorers will be consumed.
        boost - The boost that is propagated by the parent queries.
        Throws:
        java.io.IOException
      • toString

        public final java.lang.String toString​(java.lang.String f)
        Prints a user-readable version of this query.
        Specified by:
        toString in class Query
      • termArraysHashCode

        private int termArraysHashCode()
      • termArraysEquals

        private boolean termArraysEquals​(Term[][] termArrays1,
                                         Term[][] termArrays2)
