That's the right one.

It's a case-insensitive, non-rooted search specification.

This works in a similar way to 'subject:"some phrase"', (though more
people seem to be asking about these details for folder: than have ever
asked for subject:).

This is the easiest kind of searching to get out of Xapian. However, in
the future, I would like to enable users to specify rooted search
specifications, (whether with folder:, subject:, or any other prefix).

That will require a little care to get some additional terms indexed to
support the rooting, then the in-development custom query parser to
allow mapping symbols like '^' and '$' to these new symbols.
