Updated Magic queries documentation

As part of a continuing effort to update and improve documentation, the first information on magic queries is now available.

Sometimes you want data from ShadowTrackr that you know is in there, but cannot get out with the query language. A good example is if you want to combine data from two or more indexes. The query language does not support joins. This is where magic queries are used.

All magic queries start with a $. There are a number of existing ones, and they are now listed in the documentation. For quick access, just type $ in the search bar in the gui and auto-complete will show you what's available.

If you cannot find the magic query that you need, contact support and we'll try to make a new magic query for your specific needs.
