I'm looking for a plugin or a idea so that my WP 3.1 search engine can index PDF files. Has anyone be through that need too ?
The standard WordPress search is pretty basic and only search the database, there are some plugins that extend the search functionality to search even more parts of the database like:
but they do not have the ability to search files. There is one plugin that i know of that claims to support indexing PDF and DOC files
But the best solution I have used for this kind of "Job" is Google custom search that searchs PDFs and DOCs and is fairly easy to set up.
You can use SearchBlox which provides a plugin to connect the search server with Wordpress
