Thanks dmitri for your valuable response. I just got to know that Lucy only provides sub-set of features Lucene provides. Would like to know if you know any critical features Lucy is lacking. I think my requirement is not complex. I need to index file system periodically.. need full-text search including HTML, DOC, XLS, PDF etc types.
Thanks again.
I've never used Lucene, so I cannot compare the two. I use Lucy to index PDF, HTML, DOC, and a several other document types. Converting them into text indexable by Lucy has to be done separately.
I've graduated from reindexing once every few hours using cron job to using Linux::Inotify2 to provide practically instant updates to the index. Surely impressed my $boss...
