How do you set up IndexWriter (can you paste the code here)? setMergeFactor just controls how often merges will occur. But there are other settings, like setRAMBufferSizeMB and setMaxBufferedDocs that control how often to create a segment. If for example you set maxBufferedDocs to 1, or RAMBufferSizeMB to a small value, such that each document fills the entire buffer, you'll run into the scenario you mentioned.
If that's not the case, then it'd be good if you can paste here the indexing code including the IndexWriter setup, docs indexing etc. Shai On Sun, Jul 26, 2009 at 8:25 AM, Venkat Rangan < venkat.ran...@clearwellsystems.com> wrote: > Hi, > > > > We are writing to an index using IndexWriter with setMergeFactor() set > to 10.
