No of docs using IndexSearcher
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]

Re: No of docs using IndexSearcher
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))? 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?

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.
