You might want to look at the source code for the open source project GExperts. It contains a text search engine (grep) that works very well.

If you are on a unix system, send a call to grep. If you are on a windows system, install grep for windows.

I have written something similar in C# - Searcharoo.net - you can download the source code from there.

What might be more useful, though, are the articles that I wrote describing how it works... This description of how Version 1 might be of some use - although I'm probably biased since I wrote it (back in 2004).

Your question is pretty open so I'm not sure if this will help - particularly since I don't know Delphi and how different it is to C# - but hope it helps...

Basically you need to find a string in another string. Take a look at this algorithm: http://en.wikipedia.org/wiki/Knuth-Morris-Pratt_algorithm
