Problem with multiple indices and multisearcher
-----------------------------------------------
Key: LUCENENET-27
URL: http://issues.apache.org/jira/browse/LUCENENET-27
Project: Lucene.Net
Issue Type: Bug
Environment: Windows XP, Visual Studio Pro 2005, Lucene .net 1.9 Final
RC build 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.
Here is the error I get:
Object reference not set to an instance of an object.
