ok, yes my use case is being able to look for several words with AND and/or
if searchable_text is a field with all text the package has:

search('nose AND plugin')

--- which in my mind would result in something like:

select distinct package_name
from package
where searchable_text like '%nose%' AND name like '%plugin%'

But i guess it can be rather complex, and Noah's trick fit my needs :D

semi-related: looking at the code, I think query_packages can be called just
per term, then the score calculated for each column on the results. That
lower the number of queries (1/3).

if it is doable, that would be nice,

Maybe we could have an advanced search screen that would take care of asking
the user which field the term refers too (like roundup) ?
