RiSearch Pro v.3.2 Manual© S. Tarasov
After you update your site it is possible to add updated and new documents into index without full reindexing. Use admin panel ("Update site").
If you choose "update local filesystem" method, script will look for new (modified) files in all directories below base_dir.
