Hi, I'm a little confused about how the tuning params in solrconfig.xml actually work.
My index currently has mergeFactor=25 and maxMergeDocs=2147483647. So this means that up to 25 segments can be created before a merge happens, and each segment can have up to 2bn docs in, right? But this page: http://www.ibm.com/developerworks/java/library/j-solr2/ says "Smaller values [of maxMergeDocs] (< 10,000) are best for applications with a large number of updates." Our system does indeed have frequent updates. But if we set maxMergeDocs=10000, what happens when we reach 25 segments with 10000 docs in each? Is the mergeFactor just ignored, so we start a new segment anyway? More generally, what would be reasonable params for a large index consisting of many small docs, updated frequently? I think a few different use-case examples like this would be a great addition to the wiki. Thanks!
