The reason is attribute filters are different to fields.
For example, :conditions => {:country => "Melbourne"} becomes
"@country Melbourne" when sent through to Sphinx - as that's how it
expects field-specific searches. And they get appended to the main
query.
Book.search "Discworld", :conditions => {:country => "United
Kingdom"}
# is sent to Sphinx as:
"Discworld @country United Kingdom"
If you specified nothing for country, then that would become
"Discworld @country" - and so it has nothing to match on the country
field.
Filters are completely separate - they are not part of the query
string, but sent through to the Sphinx daemon one by one. Nil is
treated as 0 by Sphinx, and so can be a valid match.
Not the best description I've written, but hopefully it sheds some
light.
Cheers
