    • Constructor Detail

      • QueryTermVector

        public QueryTermVector​(String[] queryTerms)
        Parameters:
        queryTerms - The original list of terms from the query, can contain duplicates
      • QueryTermVector

        public QueryTermVector​(String queryString,
                               Analyzer analyzer)
    • Method Detail

      • size

        public int size()
        Specified by:
        size in interface TermFreqVector
        Returns:
        The number of terms in the term vector.
      • getTerms

        public String[] getTerms()
        Specified by:
        getTerms in interface TermFreqVector
        Returns:
        An Array of term texts in ascending order.
      • getTermFrequencies

        public int[] getTermFrequencies()
        Description copied from interface: TermFreqVector
        Array of term frequencies. Locations of the array correspond one to one to the terms in the array obtained from getTerms method. Each location in the array contains the number of times this term occurs in the document or the document field.
        Specified by:
        getTermFrequencies in interface TermFreqVector
      • indexOf

        public int indexOf​(String term)
        Description copied from interface: TermFreqVector
        Return an index in the term numbers array returned from getTerms at which the term with the specified term appears. If this term does not appear in the array, return -1.
        Specified by:
        indexOf in interface TermFreqVector
      • indexesOf

        public int[] indexesOf​(String[] terms,
                               int start,
                               int len)
        Description copied from interface: TermFreqVector
        Just like indexOf(int) but searches for a number of terms at the same time. Returns an array that has the same size as the number of terms searched for, each slot containing the result of searching for that term number.
        Specified by:
        indexesOf in interface TermFreqVector
        Parameters:
        terms - array containing terms to look for
        start - index in the array where the list of terms starts
        len - the number of terms in the list
