[jira] [Created] (LUCENENET-488) Can't open IndexReader, get OutOFMemory Exception
Steven created LUCENENET-488: Summary: Can't open IndexReader, get OutOFMemory Exception Key: LUCENENET-488 URL: https://issues.apache.org/jira/browse/LUCENENET-488 Project: Lucene.Net Issue Type: Bug Components: Lucene.Net Core Affects Versions: Lucene.Net 2.9.4g Environment: Windows server 2008R2 Reporter: Steven Have build a large database with ~1Bn records (2 items per document) it has size 200GB on disk. I managed to write the indexe by chunking into 100,000 blocks as I ended up with some threading issues (another bug submission). Anyway the index is built but I can't open it and get a memory exception (process explorer gets to 1.5GB allocated before it dies but not sure how reliable that is, but do know there is plenty more RAM left on the box).

Is this correct? Does it work if you're calling the overload of IndexReader.Open which accepts a termInfosIndexDivisor directly? (You can pass null for deletion policy to use the default deletion policy.) The default termInfosIndexDivisor is one, increasing it will decrease the amount of memory required. This will slow down some term-related operations against the index, but it sounds better than not being able to open it at all.

I will try to build a native 64bit version on the server itself (my development box is only 32 which might be the problem) and let you know how I get on. Thanks again, can't believe you guys do this for free, I pay millions for products that aren't any where near as good! > Can't open IndexReader, get OutOFMemory Exception > - > > Key: LUCENENET-488 > URL: https://issues.apache.org/jira/browse/LUCENENET-488 > Project: Lucene.Net > Issue Type: Bug > Components: Lucene.Net Core >Affects Versions: Lucene.Net 2.9.4g > Environment: Windows server 2008R2 >Reporter: Steven > > Have build a large database with ~1Bn records (2 items per document) it has > size 200GB on disk.
