Hi,
It looks like my index is not really optimized, because in the index directory I can see 28 .cfs files (see below) Basically I see files modified on October 3trhd which are only 3KB, when the last files date is October 15. There is only two big files(_fdm.cfs and _uz1.cfs) of 34 and 29 M each. All others are under 3 M. I don't think that's really normal. I'm not calling the normalize() method of the IndexWriter, because my index is updated quite regularly, and I didn't change the merge factors which should then be the default of 10. >From a different post I've read on this mailing list, I thought by letting >this default the optimization will be done automatically every 10 documents >added to the index (and then every 10 segments, they should be merges..). But >for some reason it doesn't seem to happen this way. Am I missing something here ? When do we know if the optimization is done ? Is it possible to know when the last optimization has been done, or something like that ? 3368080 Oct 4 01:37 _11df.cfs 3556203 Oct 4 03:23 _12to.cfs 3202442 Oct 4 05:19 _1461.cfs 3266858 Oct 4 08:29 _15ru.cfs 2690783 Oct 4 10:49 _171z.cfs 1914828 Oct 5 06:30 _18bk.cfs 2136812 Oct 11 10:03 _19ct.cfs 2193955 Oct 12 23:06 _1ajw.cfs 76461 Oct 13 02:23 _1aph.cfs 59414 Oct 13 02:24 _1aus.cfs 71326 Oct 13 02:25 _1axv.cfs 165463 Oct 13 04:28 _1b0y.cfs 308954 Oct 13 04:53 _1b41.cfs 321472 Oct 13 05:27 _1b74.cfs 5893 Oct 13 05:27 _1b75.cfs 6386 Oct 13 05:27 _1b76.cfs 6302 Oct 13 05:27 _1b77.cfs 5766 Oct 13 05:27 _1b78.cfs 5772 Oct 13 05:27 _1b79.cfs 6702 Oct 15 08:18 _1b7a.cfs 6240 Oct 15 08:33 _1b7b.cfs 35508431 Oct 2 07:51 _fdm.cfs 29931133 Oct 3 15:56 _uz1.cfs 3075659 Oct 3 19:01 _wkk.cfs 3605056 Oct 3 21:31 _y77.cfs 3437364 Oct 3 23:29 _zsg.cfs 20 Oct 15 08:33 segments.gen 639 Oct 15 08:33 segments_2meq Thanks, Mélanie
