Welcome to the manual of regain.
regain is a search engine similar to web search engines like Google. Using regain you can search through large portions of data (several gigabytes!) in split seconds! This is possible by using a search index. regain crawles through your files or webpages, extracts all text and puts it in a smart search index. All this happens in the background. So if you want to search something you get the results immediately.
There are two variants of regain: The desktop search and the server search. The desktop search is to be used on a normal desktop computer and it offers you a fast search for documents or intranet webpages. The server search you can install on web servers. It provides searching functionality for a website or for intranet fileservers. To learn more about the differernces of these two variants read the Comparison of the regain variants.
