RE: No of docs using IndexSearcher
I'm fairly new to lucene. The main reason why I did n't use the IndexReader constructor for the searcher is we organize the indexes as different partitions depending on document's date and during searching I instantiate a MultiSearcher object on these different partitions depending on from-date and to-date from the search. I was getting a runtime exception during search, If the index does not have any documents. That's why I was looking for some method on the searcher object that gives me the number of documents.

If your index is open shouldnt there be an instance of IndexReader already there? Ravi said the following on 12/10/2004 3:13 PM: I already have a field with a constant value in my index. How about using IndexSearcher.docFreq(new Term(field,value))?

RE: No of docs using IndexSearcher
I already have a field with a constant value in my index. How about using IndexSearcher.docFreq(new Term(field,value))? Then I don't have to instantiate IndexReader. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, December 10, 2004 2:59 PM To: Lucene Users List Subject: Re: No of docs using IndexSearcher numDocs() http://jakarta.apache.org/lucene/docs/api/org/apache/lucene/index/IndexR eader.html#numDocs() Ravi said the following on 12/10/2004 2:42 PM: > How do I get the number of docs in an index If I just have access to a >searcher on that index? > >Thanks in advance >Ravi. > >- >To unsubscribe, e-mail: [EMAIL PROTECTED] >For additional commands, e-mail: [EMAIL PROTECTED] > > > > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
