Desktop Decision Desktop Search for Windows

Desktop Decision Desktop Search has a simple user friendly interface, high performance and small size. In distinction from Windows built-in search engine it creates a database of words at first run (and so on according to request, any time in future).

and after that you can perform searches very fast. Just type needed keywords in the search box (one or more, or just the first characters a word begins with), the program will find a list of documents, containing your words and you can open found documents with associated program.
