Subject Re: performance differences between 1.4.3 and 1.9.1
Date Thu, 27 Apr 2006 00:18:40 GMT
For my application we have several hundred indexes, different subsets
of which are searched depending on the situation.  Aside from not
upgrading to lucene 1.9, or making a big index for every possible
subset, do you have any ideas for how can we maintain fast
performance?
