Re: Lucene on Windows
The CVS version of Lucene has a patch that allows one to use a 'Compound Index' instead of the traditional one. This reduces the number of open files. For more info, see/make the Javadocs for IndexWriter. Interesting option. Do you have a rough idea of what the performance impact of using this setting is? -- Eric Jain - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Lucene on Windows
A very rough and simple 'add a single document to the index' test shows that the Compound Index is marginally slower than the traditional one. I did not test searching.

At 400 I get a too many open files error. Note: the default mergeFactor of 10 should give no trouble. Please note that it is never recommended that you set mergeFactor anywhere near this high. I don't know why folks do this. It really doesn't make indexing much faster, and it makes searching slower if you don't optimize. It's a bad idea. The default setting of 10 works pretty well. I've also had good experience setting it as high as 50 on big batch indexing runs, but do not recommend setting it much higher than that. Even then, this can cause problems if you need to use several indexes at once, or you have lots of fields.

Lucene on Windows
Hi, Wonder if anyone can help. Has anyone used Lucene on a Windows environment? Anyone know of any documentation specifically focused on doing that? Or anyone know of any gotchas to avoid? Thanks for any help, Cheers Steve.

Its pure Java and works the same on all supported platforms. So no real gotchas with respect to Windows.

FYI - On my linux box, I got the 'too many open' error on mergeFactor=300 (and 200). So, I am using 100.
