I've been using Family Search AI text search for the past week and it is a WOW! Have found so many "missing" documents. They say it is limited to only 2 collections but I have been getting responses from many other collections. Be sure to check out the filter options in upper left corner for location, date, etc. Double click United States to get list of states and click state to get counties. Same for other options. And don't miss the download option - the tiny arrow above the OCR transcription.
