GroupDocs.Search for .NET can cache text of indexed documents in an index. This cached text is then used to rapidly generate HTML markup by highlighting search results. This approach is lot faster than extracting text directly from files. Retrieving text from cache will be available even if the source files are no longer available. The cached text can be stored by applying various compression levels to occupy lesser disk space and faster indexing time.
