Subject [jira] Commented: (LUCENENET-388) Exception: will crash and restart the web-application.
Date Fri, 21 Jan 2011 19:21:51 GMT


Patric Forsgard commented on LUCENENET-388:

Yes, the searcher I will use is the ParallelMultiSearcher. It would be good if you found a
good way so I can catch the exception. I have try by my self but its hard to understand everything
in the source the first time I open it up.

For my index i found that I have some deleted document that not yet was purged that cause
the query to crash, i'm not sure what information that was on the deleted index and what was
missing, i have not found a way in luke to browse the deleted documents to see whats wrong
with them.

I think it should get the exception, but it should not crash the site and restart the application
each time.
