I'm looking for preferably free software that will allow one to search a private collection of PDF's and other document and e-book formats for words or sentences in the book.
My purpose is to quickly find citations and relative passages based on search queries. I would like the query to present the file that contains the match, the page number, a sample of the passage, and option to open it up to read it in the passage's entirety. I don't need all these feature but does something like this exist?
I run Linux, FreeBSD, OSX, and Windows, so software for any of these operating systems will do.
