Hi,
I am facing the problem
The line in the loop is going very slow giving me a performance hit
for (int i = 0; i < hits.length; ++i) {
int docId = hits[i].doc;
Document d = searcher.doc(docId); //problem
}
How can I improve this. Please give me an example of the improved code
Thanks,
Suman
Ps :
In one of post Erick said ..
this line is really suspicious:
Document document = this.indexReader.document(doc)
>From the Javadoc for HitCollector.collect:
Note: This is called in an inner search loop. For good search performance,
implementations of this method should not call
Searcher.doc(int)<file:///C:/lucene-2.1.0/docs/api/org/apache/lucene/search/
Searcher.html#doc%28int%29>or
IndexReader.document(int)<file:///C:/lucene-2.1.0/docs/api/org/apache/lucene
/index/IndexReader.html#document%28int%29>on
every document number encountered. Doing so can slow searches by an
order
of magnitude or more.
