    • Constructor Detail

      • SpanNotQuery

        public SpanNotQuery​(SpanQuery include,
                            SpanQuery exclude)
        Construct a SpanNotQuery matching spans from include which have no overlap with spans from exclude.
    • Method Detail

      • getInclude

        public SpanQuery getInclude()
        Return the SpanQuery whose matches are filtered.
      • getExclude

        public SpanQuery getExclude()
        Return the SpanQuery whose matches must not overlap those returned.
      • getField

        public String getField()
        Description copied from class: SpanQuery
        Returns the name of the field matched by this query.
        Specified by:
        getField in class SpanQuery
      • extractTerms

        public void extractTerms​(Set<Term> terms)
        Description copied from class: Query
        Expert: adds all terms occurring in this query to the terms set. Only works if this query is in its rewritten form.
        Overrides:
        extractTerms in class Query
      • toString

        public String toString​(String field)
        Description copied from class: Query
        Prints a query to a string, with field assumed to be the default field and omitted.

        The representation used is one that is supposed to be readable by QueryParser. However, there are the following limitations:

        • If the query was created by the parser, the printed representation may not be exactly what was parsed. For example, characters that need to be escaped will be represented without the required backslash.
        • Some of the more complicated queries (e.g. span queries) don't have a representation that can be parsed by QueryParser.
        Specified by:
        toString in class Query
      • clone

        public Object clone()
        Description copied from class: Query
        Returns a clone of this query.
        Overrides:
        clone in class Query
      • rewrite

        public Query rewrite​(IndexReader reader)
                      throws 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.
        Overrides:
        rewrite in class Query
        Throws:
        IOException
      • equals

        public boolean equals​(Object o)
