[jira] Created: (LUCENENET-28) Problem with multiple indices and
multisearcher
Problem with multiple indices and multisearcher
-----------------------------------------------
Key: LUCENENET-28
URL: http://issues.apache.org/jira/browse/LUCENENET-28
Project: Lucene.Net
Issue Type: Bug
Environment: Windows XP, Visual Studio Pro 2005, .Net 2.0, Lucene .net 1.9 Final RC 007
Reporter: Vivek Gupta
Hi,
I am working on a project where we have created an application that searches an index that is created by a service. The service continually watches a directory and updates the index. This part works fine. I have now added a second index created by another application. I would like to be able to search across both indexes. So I made changes to my first application so that it uses multisearcher passing in an array of searchers for both of the indexes I want to search. However, this seems to result in an error (shown further down). Also, both indexes have the same fields and either one works fine by itself, it is just when multisearcher is introduced that I end up with a problem. The first query typically works, but queries after that fail and it is independent of whether or not the index is in the process of building (though it may be more often when one of the indexes is still being updated).
Here is the error I get:
Object reference not set to an instance of an object.

[jira] Closed: (LUCENENET-28) Problem with multiple indices and

George Aroush closed LUCENENET-28.
----------------------------------
Resolution: Invalid
Hi Vivek,
What you are reporting is not necessarily a defect in Lucene.Net; it is more like a question. Please post this question on the Lucene.Net development form with a sample code which re-creates the problem and someone should be able to help you.
I am closing this issue.
Regards,
-- George
