Are you sure you are using the same Searcher for every search? Don't
open a new one unless you have modified the index. You are iterating
over every hit with the Hits class. You don't ever want to do this. Use
a HitCollector if you want to iterate over more than a hundred or so
hits. You will find further info about this if you check out the Lucene
webpage, the faq: http://wiki.apache.org/lucene-java/LuceneFAQ and the
wiki:
http://wiki.apache.org/lucene-java/FrontPage?action=show&redirect=FrontPageEN
especially http://wiki.apache.org/lucene-java/ImproveSearchingSpeed.

Sure.
public float doBodySearch(Searcher searcher,String query, int id){
try{
score = search(searcher, query,id);
}
catch(IOException io){}
catch(ParseException pe){}
return score;
}
private float search(Searcher searcher, String queryString, int id) throws
ParseException, IOException {
// Build a Query object
QueryParser queryParser = new QueryParser("contents", new
KeywordAnalyzer());
queryParser.setDefaultOperator(QueryParser.Operator.AND);
Query query = queryParser.parse(queryString);
// Search for the query
Hits hits = searcher.search(query);
Document doc = null;
// Examine the Hits object to see if there were any matches
int hitCount = hits.length();
for(int i=0;i<hitCount;i++){
doc = hits.doc(i);
String str = doc.get("item");
int tmp = Integer.parseInt(str);
if(tmp==id)
score = hits.score(i);
}
return score;
}
I really need to optimize doBodySearch(...) as this takes the most time.
thanks guys,

Could you show us the relevant source from doBodySearch()?

I ran some tests and it seems that the slowness is from Lucene calls
when I
do "doBodySearch", if I remove that call, Lucene gives me results in 5
seconds. otherwise it takes about 50 seconds.
But I need to do Body search and that field contains lots of text. The
field
is <contents>. How can I optimize that ?
thanks,
