Are term vector position returned ordered in Lucene 3.6?

[andi rexha]

Hi, 
I am extracting term vectors position in Lucene 3.6. First I extract the term 
vector and get the indexes from the "indexOf" method as suggested for 
extracting the position.

TermPositionVector termFreqVector = (TermPositionVector) 
reader.getTermFreqVector(i, termField);
String[] terms = termFreqVector.getTerms();
int[] indexesOf = termFreqVector.indexesOf(terms, 0, terms.length);

Is the indexOf the same as the terms index?

My main question anyway is weather I can assume that the position returned from 
the position is ordered :


                    int[] termPositions = 
termFreqVector.getTermPositions(indexesOf[j]);


so can I assume that  termPositions[i] > termPositions[j] for i > j   ??


Thank you!
