I noticed that a number of contributors were praising Archivarius, so I thought I would give it a go.  On the site it says, "you may try it in a fully functional version. The trial period is 30 days"  After installing it and running it, I discovered that the trial version only indexes 10,000 files ( as well as only allowing 100 accesses).  Only 10,000 files is a joke - how can you evaluate a search engine like that???  Of course it will be lightning quick!

Needles to say, Archivarius was instantly removed from my PC and will not be on it again.

Here I must have a rant.  I find nothing more irritating and annoying than software being promoted under false pretences.  ( a similar ploy is software promoted as being freeware and then you discover it is trialware).  Do software purveyors not realise that if you can't trust your first contact with them, you are unlikely to trust them thereafter, and unlikely to do business with them?

Incidentally, I use X1 Enterprise Client Version 5.6.2 which is free and does allow indexing of PST files in any folder, which seems not to be the case with the latest version on their site, 5.6.4, so I have not updated (and still have the setup file).  The only problems I find with X1 are that it sometimes corrupts the PST files, and is slow to wake up from the tray.  But the searching and previewing are good.  So looks like I'm going to stick with it for now.

Using the latest release, v1.13.01, I cannot get the keyword modifiers for folders to work at all.  If I put no keyword modifier in for a folder, then the files of that folder show up in the search.  But as soon as I try to put a keyword modifier in, for example DOX, I get no files at all from that folder - whether or not I type in +DOX in the FARR entry box.

Can someone help me here?  I have tried different keywords, and enclosing them in quotation marks.  Incidentally, I discovered a bug.  If you put a space in before your keyword in the Optional Keyword Modifier box in the Search Directory Options, the next time if you just type in + in the FARR entry box, it crashes.
