I wish I had discovered FTP years ago. This is one of the best apps there is IMHO. If you have not realized it yet, Apple’s Finder is not perfectly reliable. During ten years of legal wrangling with the VA I had so many research papers, submissions, rejections, and rebuttals, not to mention all the research to support my arguments, and not to mention fighting with the Air Force to correct my records, I was very frustrated on more than one occasion. I was using HoudahSPot or other Finder liked (spotlight driven) search tools to find words I knew I had previously used (but could no longer remember which revision of a document I had used that term in). But my spotlight driven searches would too often show no results - even after I rebuilt the Spotlight.
FTP changed everything for me. It is obsessively easy to schedule all the databases to be updated once a day as in 3 am or whenever you say. It is also very easy to tell FTP to rebuild or update any particular database that you have been using. One of the best parts, besides finally having reliable search results that I was not getting in Finder, is that when I am looking for something in a text document such as Scrivener, I don't have to open each document to see why the search engine said there was a result there for me, That is how HoudahSpot and other Finder based search tools work, you have to pen each document to find and copy out the phrase you were looking for to support your new submission with your old arguments. FTP provides an actual preview that allows you to search in and copy out of - without having to open each and every document.
It also has a feature that I think is somewhat similar to NeoFinder, although NeoFinder never really took off for me. NF is supposed to be this great idea where you can catalog all your disks and volumes and find what you were looking for even if a volume is not currently mounted. That is the same thing that FTP does only it does it far better, especially when it comes to text. I can confidently recommend this program, especially if you depend on doing a a lot of writing, a lot of research, or just wanting an accurate result when searching with Finder.
