I know that this is a support forum and not the place to submit feature requests, but I'd really like to promote the following suggestion, and invite comments:
Obviously Opus 10 now supports Windows Search, but it only does so in a bare-bones fashion: If I want to perform a more sophisticated search, I need to construct an AQL (Advanced Query Language) syntax query myself, and manually. What I would like to see is a nice GUI interface, similar, or even identical to the one I can have for Opus' built-in Find functionality (or similar to the one that Microsoft had originally provided in Vista, which was then scrapped and mangled in Windows 7... 
).
Doing so should be extremely straightforward for the developers, since all they need to do is translate the data in the current forms they have for the internal Find function into AQL, which is an entirely linear and straightforward process. This way users can more easily take advantage of the far superior performance of Windows' Search Index. Opus' built-in Find function is fine, I suppose, for queries that do not depend on file contents, but if I need to search for file contents, then it is next to useless for anything but the most limited searches. If I need to go through thousands of files, including PDFs, Word documents, etc., to find the ones that contain certain strings, then I can go have lunch first before I can come back to see the results. I suspect that Opus' Find also does not make use of the installed Search Filters, so it will not be able at all to search the content of a number of file types (PDF possibly being one of them).
So, what sayeth you, oh mighty Opus developers?
