we are trying to add searching to our web site and want this search function to search only a few things:
- Files - Obviously we need to parse the text of PDF, PPT and DOC files in our case
- User comments. Users will be available to comment on the stuff and we want to catch if some user is searching for that relative information
I would like to have your advices on how to develop such a system. Should we get an external search system such as Google's or just install an open source one or develop a new one from scratch.
Thanks.
