OK. If your index directory has *.cfs files, then you are using the default compound file format (I'm not sure whether Compass changes that default either). > How the ramBufferSizeMB parameter affect the files size? What value should I > use in order to have 6MB files? ramBufferSizeMB controls how big the initially created segments are. Just how big a segment you get for a given ramBufferMB is very app dependent, because the RAM efficiency of IndexWriter depends on things like whether you have many unique terms (= worse RAM efficiency). Generally larger RAM buffers have better efficiency. Merging can only create bigger segments from those flushed segments. So, you have to ensure ramBufferSizeMB is set such that in your use case it never up and flushes a segment bigger than your 10 MB size limit.
