I have a small Mediawiki (around 6000 pages) and currently using MWSearch(recent) and Lucene (2.1) and have a problem with Lucene where I get "java.io.FileNotFoundException:.../segments_u (No such file or directory)"; I have created a scripted solution around this but its slightly inefficient to rebuild my indexes THAT often as this happens 3-6 times a day. It seems a few people have posted about this issue on the Discussion portion of the Lucene page but no traction, is this issue just rare and caused by some incorrect configuration on my part? or do other wiki's have this issue as well? I am guessing the main Wikipedia is using the 2.1 branch of Lucene as it has "Did you mean" functionality which appears to be only apart of the 2.1 tree, and if this is true how do they deal with it? Any advice is appreciated, thanks in advance!
