UPDATE: Please accept our sincerest apologies for any miscommunication, though the new Advanced Search feature is currently only available within our TCS Cloud offering. We are looking to include this functionality in a future release of MindTouch Platform v 10.1.
MindTouch Core, Platform and TCS all ship with a new advanced search feature that takes a normal query and gives you a dedicated UI for going into further detail about what you want. Advanced search allows you to refine your queries by including “all of these words” “exact phrase” “any of these words” or “been tagged with.” You can also filter results by “do not have these words” “by author” “by type:pages, images, comments, or documents.” If you are a TCS customer, these results are going to feed into your search analytics as well.
You can read more about advanced search and see some screenshots over on help.mindtouch.us.
