* Allow a user to obtain search results for a particular subsite when the request comes from a query
When attempting to do this in project code, SearchVariantSubsites kicks in and replaces any filter you've applied with the current subsite ID, which prevents you from searching for filtered results in another subsite.
This fix prevents the module from doing this if a filter is applied on the query
TODO write unit tests for the filter() and exclude() behaviours
When the database isn’t yet created, $current is set, but
$current->currentDatabase() is empty. I suspect this only applies to
PDO connections. It results in errors during startup.
This check fixes it.
Stopped indexing of classes which were unrelated to overall variants.
For example, an index with excludeVariantState(array('SearchVariantVersioned' => 'Stage'))
should only set this variant state on types where appliesTo() returns true, namely "Page".
Without the $class parameter it also returned on "File" index requests,
which then lead to all index requests being discarded later on somewhere in SearchUpdater.
Regression introduced in 625d282.
