D'oh! You're right. I was able to reproduce the error on my system too,
with the 3.1.1 pre-release!

If you try a boolean search for "tool bar", it does give the error
message "expected 'AND' or 'OR' instead of 'bar'", but with the query you
suggested, the error message is blank. A peek at htsearch/
shows two spots in parser::factor() where valid is set to 0, but error is
not set to anything. There's your bug. I don't really understand the
parser well enough to suggest meaningful error messages to put there,
but perhaps someone else could give it a go.

My stab at it would be

        expected ')' instead of 'foo'

for the first case, and

        expected a word instead of 'foo'

for the second. Makes sense?
