Subject Re: High number of files in the index
Date Mon, 05 May 2003 05:58:24 GMT
The most obvious reason seems to be the increase in number of fields.
 I guess lucene creates one file for each field in the index.
You can check by looking at the file names in the index, if you have N
number of files with the common prefix ,
but different suffix , those are all created for different fields.

And also , is the lucene performance affected by the no of files in the
index. I think u can look at the index size as a whole
And if it affects the performance, is there a way to merge the files and do
further optimization?.. as I have not much info about the additional files
created in the index.
