You can't.  Can you do it in Google or any other search engine?

You can do -w "swish search" not "engine" but that means you need to know
the execption.

Swish builds a reverse index, it's not a database that is searching
fields.

What I have done in the past is make "doc_keyword" a property, too.  Then
return that property on search results and filter the results.  This
messes things up if you are using -b and -m for paged results[*].

We have also talked about adding "strucrture" bits to flag the first and
last words of a metaname so you can do something like:

   -w "^swish search$" (looks a little regex like)

to flag to the search code to find "swish" but only if it's at the first
position and "search" if it's the last postion.  That's a ways off, I
think.

The other thing  people ask for somewhat often is "How can I find docs
that have *anything* set for a given metaname?"  In other words, find docs
where a meta is defined and exclude docs where the meta is not defined.


[*] In that case I didn't use paged results from swish, and instead I'd
fetch all results up to a limit, then cache the results using File::Cache
in Perl.  Very fast for fetching the next page of results.  Also good if
the same query is run often (e.g. you have links that query swish).
