Hello,
Where is the best documentation on performing searches?
I have noticed some quirks:
\label:VLSCI
finds nothing, even though lots of emails are labeled VLSCI.
\label:vlsci
finds all these emails.
\label:vlsci \label:unread
finds all vlsci OR unread emails - I would have assumed that should be AND?
How do I perform and AND operation?
Thanks

The above looks like you are doing them one at a time. If you do this:
\label:vlsci label:unread
that should do what you want.
Also, on the search results view, hitting '|' let you refine the search
so:
\label:vlsci | label:unread
should also do what you want.

I fell into these traps as well (there was a thread in this list two
months ago, search for this message: 1276181871-sup-2536@zyrg.net).
I started to rewrite the page SearchingMail in the Wiki:
http://sup.rubyforge.org/wiki/wiki.pl?SearchingMail
The information on that page should be correct, but certainly is not
complete. Neither is it easy to grok.
As a start, the basic query language is described in
http://xapian.org/docs/queryparser.html.
Some stumbling points about searching in Sup:
- By default, query terms are combined with AND
- Exception: Query terms within the same field type are combined as OR
I.e. a search for "label:ruby-talk subject:\[ANN\]" (without the
quotes!) is equivalent to "label:ruby-talk AND subject:\[ANN\]".
In contrast, the search "subject:apples subject:oranges" is equivalent
to "subject:apples OR subject:oranges"!

Wrong. As these are two queries in the same field type, they are ORed.
The get the result you're expecting, you must search for
"label:vlsci AND label:unread" (without the quotes).

Again, this is wrong. Refining a search will just let you append or
edit the current query. I.e. after hitting '|' you should append
"AND label:unread" to the query string.
I would really welcome if somebody with a little more insight than me
could take the time to update the documentation about searching in Sup.

You use the AND operator :-) . Apparently it's a known bug that
Xapian doesn't do AND as the implied operator when there is none
specified. So I do things like this:
is:unread AND is:inbox AND label:widgets

Ok, thanks for the information.
How do I search for all messages not containing a label? I tried:
not label:mylabel
! label:mylabel
~label:mylabel
-label:mylabel
The first finds no results. The rest are the same as "label:mylabel".
What am I doing wrong here?
What do the above searchs really do?

Looking at http://xapian.org/docs/queryparser.html, it looks like "pure
not" is disabled, at least in my sup installation. It also seems like
booleans *must* be in ALLCAPS to be recognized.
Thus:
NOT label:mylabel - gives a syntax error
not label:mylabel - is 'not OR label:mylabel' [searching for the word
"not" or for the label]
I'm getting some results from a search on 'label: NOT label:mylabel',
though I'm not sure if the results I'm getting are correct for what
you're looking for.
