Re: Increasing maxMergedSegmentMB value

Hi Jack, Yes, I plan to merge all the 10GB segments to 20GB, and not just two of the segments. Sorry for the confusion. I have recently increased the system memory from 64GB to 192GB, but as our index size grows (which means more segments are created), I found that the query speed actually slow d

Re: Increasing maxMergedSegmentMB value

Make sure you fully digest Mike McCandless' blog post on segment merge before trying to outguess his code: http://blog.mikemccandless.com/2011/02/visualizing-lucenes-segment-merges.html Generally, I don't think you would want to merge just two segments. Generally, you should do a bunch at a time,

Re: Increasing maxMergedSegmentMB value
