OutOfMemory during optimize

[Steve Rajavuori <St...@opin.com>]

I am periodically getting "Too many open files" error when searching. Currently there are over 500 files in my Lucene directory. I am attempting to run optimize( ) to reduce the number of files. However, optimize never finishes because whenever I run it, it quits with a Java exception OutOfMemory error. I have tried using the -Xmx and -Xms switches to increase heap size, but that has not helped.

Any suggestions?

You could try reducing maxMergeDocs and mergeFactor.  Doing so increases 
the time it takes to optimize, but reduces the amount of memory consumed.

Good luck!

Boost value and LUKE

[Don Vaillancourt <do...@webimpact.com>]

Hello All,

I am testing the boost value within the latest version of Lucene and I'm 
inspecting the results through Luke.

For each FIELD that I want to boost I use the setBoost method.  And 
everything looks good.  But Luke is refusing to exposure the boost value 
and keeps returning 1.0 for the specified columns (well actually all 
columns) when I have set one column to 0.5 and the other to 0.75.

1. Is there something I am doing wrong?
2. Is there a bug in Lucene?
3. is there a bug in Luke?

Anyone have any hints.

Thank You
