Subject Re: How to rebuild index
Date Fri, 21 Jan 2011 11:11:17 GMT
First of all try it on different folder than your current index folder. new
analyzer will make different index but same data. First you should create
index on different folder than just replace your new index with current
index files. If it fits, then replace the code and it will work.
