Hi, Lucene only uses CFS for very small segments, that don't exceed a specific percentage of the index size. See the method LogMergePolicy.setNoCFSRatio [http://lucene.apache.org/java/3_4_0/api/all/org/apache/lucene/index/LogMerg ePolicy.html#setNoCFSRatio(double)].
The default is 10%, every segment larger than 0.1 of total index size will not be made compound: [http://lucene.apache.org/java/3_4_0/api/all/org/apache/lucene/index/LogMerg ePolicy.html#DEFAULT_NO_CFS_RATIO] In general for merge performance reason you should not change those values, unless you are running out of file descriptors! If you have a static index that never changes (e.g. that will be hosted on a CD-ROM), you can forceMerge(1) it to one single segment with CFSRatio=1.0, in all other cases it's not a good idea, especially if you do realtime indexing; in that case you should use the new TieredMergePolicy not the old LogMergePolicy.
