Hello, Lucene javadoc defines the merge factor and mergemaxdocs as follows: int maxMergeDocs Determines the largest number of documents ever merged by addDocument(). int mergeFactor Determines how often segment indexes are merged by addDocument(). void optimize Merges all segments together into a single segment, optimizing an index for search. Using the above three, combined with the JVM heap size (-Xmx) I am trying to nail down a configuration for my application that uses Lucene for searches. A few questions regarding these - If mergeFactor determines how often segment indexes are merged, if I set it to a value > maxMergeDocs, what value gets used? I assume it is limited by maxMergeDocs. So is maxMergeDocs an upper limit for mergeFactor? If no explicit optimize() calls are used, will the segements still be merged according to the values set for maxMergeDocs and mergeFactor? Or do the mergeFactor and maxMergeDocs only get used when optimize() is called? Thanks for all the help!
