There are lots of documents in common between diferent user groups
(codgrupousuario = user group id), but each user groups can access a
subset of documents based on the types of document and data sources
(fontes) they are allowed to use.

I´d rather not create partial index (I would have to create a trigger
that creates an index each time a row is inserted on codgrupousuario).
But I'll try it to see how it performs.
The multi-column index seems a good idea.
