I have a large number of PDFs that need to be published online.
Currently I use a database to store keywords for each PDF (as well as other meta data and the filename in order to provide a link).
I use an HTML search form and some PHP code which then uses the keywords in the database to match records and provide a results page with the titles and links to the PDFs
However, maintaining extended lists of keywords for each PDF is terribly time consuming.
Instead I'd like to use software that automates that process by being able to search the contents of the PDF files themselves. It would have to be something I can deploy on a website, not a desktop application.
Is there such a software?
