Crash when deleting items concurrent with a search, crash on blooming deleted id #6

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. When deleting something from Thrudex concurrent with a search, sometimes
it will crash
2. Restarting Thrudex crashes at the bloom stage

What is the expected output? What do you see instead?

If you are able to reproduce this could you attach a backtrace of the crash?  I 
can take care of the bloom filter 
error.

Thrudex now checks if the document is deleted before it adds it to the filter.
