I have a strange problem with search strings including multiple labels.
I was at the impression that the search
label:somelabel label:anotherlabel
should find mail with both labels attached (i.e. an AND search for both
labels).
But it doesn't work that way for me (I'm using Sup next from Git). It
returns way more hits than expected.
"label:LABELDOESNTEXIST label:list" returns all mails with the label
"list" attached, although it should find nothing.
In contrast, "label:LABELDOESNTEXIST from:me" returns zero mails, as
expected, just as e.g. "label:LABELDOESNTEXIST before:yesterday".
"label:LABELDOESNTEXIST is:unread" on the other hand, gives unexpected
hits as well (I guess 'is:unread' is converted into a label search?)
Regards,
Gregor Hoffleit

I ran into this confusing behavior a while back when I upgraded from a
ferret index to a Xapian index. It appears that the query language
now requires you to use an explicit AND operator between search terms.
Without that, the implied operator appears to be an OR.

Indeed, I just noticed that the NewUserGuide.txt is much more up-to-date
than the Wiki (http://sup.rubyforge.org/wiki/wiki.pl?SearchingMail).
As a start, I copied the information from the NewUserGuide to that Wiki
page. Still, somebody who knows better should update that page.
Furthermore, I marked the information in "Testing Xapian" as obsolete in
the Wiki.
Still, it is not clear to me what happens without explicit AND or OR
operator.
"label:somelabel label:anotherlabel" seems to be equivalent to
"label:somelabel OR label:anotherlabel".
"label:ruby-talk subject:\[ANN\]" seem to be equivalent to
"label:ruby-talk AND subject:\[ANN\]".
The Xapian QueryParser documentation (http://xapian.org/docs/queryparser.html)
is not clear about this either.

Unless you use an explicit AND, boolean terms of the same field will be OR'd.
