Subject Re: Class in Lucene that Perform Search
Date Thu, 03 Jul 2008 08:03:01 GMT

Ah, thanks! I am clear now. Have to change tactics to achieve what I need.
Which class during indexing time will create the .frq file?

If possible, I want to add an extra value into it so that I can retrieve the
information during the searching process. Thank
