public QueryTermVector (String queryString, Analyzer analyzer)

Public Methods

public String getField ()

The Fieldable name.

Returns
  • The name of the field this vector is associated with.

public int[] getTermFrequencies ()

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.

public String[] getTerms ()

public int indexOf (String term)

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.

public int[] indexesOf (String[] terms, int start, int len)

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.

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

public int size ()

public final String toString ()
