Hi,
I'm currently working with Lucene 2.3.1.
The aim of my application is to querying(from an HTML form) my lucene
index, then displaying results (in a web page)with:
- Matching Strings
- Matching String positions / offsets
For example:
-The document:
when i was a child, i was a Jedi.
-The query:
w*
I would like to obtain something like:
- 3 results
- matching strings: when, was, was
-offsets: 0-3; 7-9; 22-24
I've tried to use the TermPositionVector class:
[...]
Hits hits = searcher.search(query);
for (int i = 0; i < hitCount; i++) {
TermPositionVector tfv = (TermPositionVector)
searcher.getIndexReader().getTermFreqVector(hits.id(i), "content");
[...]
I will be able to get positions with this vector, but at first, I have
to get the matching strings (when, war for the "w*" query).
According to you, what is the easier way ?
Thank you
Jérôme
