Re: Configuring Solr to use RAMDirectory
Hi Dipti, Just out of curiosity, are you trying to use RAMDirectory for improvement in speed? I tried doing that and did not see any significant improvement. Would be nice to know what your experiment shows. - Raghu On Thu, Dec 31, 2009 at 4:17 PM, Erik Hatcher erik.hatc...@gmail.comwrote: It's possible, but requires a custom DirectoryFactory implementation.

Configuring Solr to use RAMDirectory
Is it possible to configure Solr to fully load indexes in memory? I wasn't able to find any documentation about this on either their site or in the Solr 1.4 Enterprise Search Server book.
