So my question basically is: which restrictions are applied to the docset
from which (field) facets are computed?
Facets are generated based upon values found within the documents matching
your "q=" parameter and also all of your "fq=" parameters. Basically, if
you do an intersection of the docsets from all "q=" and "fq=" parameters
then you end up with the docset the facet calculations are based upon.
When you say "if I add type=book, *no* documents match, but I get facet
counts: { chapter=4 }", I'm not exactly sure what you mean. If you are
adding "q=toto&type=book&facet=true&facet.field=type" then the problem is
that the "type=book" parameter doesn't do anything... it is not a valid
Solr parameter for filtering here. In this case, all 4 of your documents
matching the "q=toto" query are still being returned, which is why the
facet count for chapters is 4.
In fact my query looks like:
q=fulltext_t%3A%28toto%29+AND+dc_type_s%3A%28book%29+%2Bdirectory_b%3Afalse&start=0&rows=20&fl=uri%2Ctimestamp%2Cdirectory_b%2Csize_i%2Cmeta_ss%2Cmime_type_ss&facet.field=dc_type_s
or without url encoding:
q=fulltext_t:(toto) AND dc_type_s:(book) (directory_b:false)
facet.field=dc_type_s
default operator is AND
... so I don't think that the query is broken like you described?
