There are times when you would want to have a local search engine capable of indexing even pdf and doc files. So here is a solution.
You can use “Omega” and here are the instructions.
download omega from http:// xapian.org/download
yum install xapian libuuid-devel
And then make and install omega and for this you can follow the instructions.
Create index using command omindex
and then you can use quest or search.py to search or you can setup the cgi way so that you can use local browser to search.
You can setup cron with following to update the index regularly:
omindex -p --db /var/lib/omega/data/default --url /URL /path/to/index
