QueryTermVector

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

public QueryTermVector(String queryString,
                       Analyzer analyzer)
Method Detail

getField

public String getField()
Description copied from interface: TermFreqVector
The Fieldable name.

Specified by:
getField in interface TermFreqVector
Returns:
The name of the field this vector is associated with.

toString

public final String toString()
Overrides:
toString in class Object

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
