Initially I thought this is a very simple requirement and created a simple application in Java, that would first extract text from PDF files and then do a linear character matching like mystring.

It did give me the expected output, but linear character matching operations are suitable only when the content you are searching is very small. The best solution is to go for a simple search engine which will first pre-parse all your data in to tokens to create an index and then allow us to query the index to retrieve matching results.

This means the whole content will be first broken down into terms and then each of it will point to the content. For example, consider the raw data,. Full Text Search engines are what I am referring to here and these search engines quickly and effectively search large volume of unstructured text.
