When building a query like this:

$query->matching($query->in('mypropery', array(1,2)));

the querybuilder caches something like "... myproperty IN ..."

When building a query like this:

$query->matching($query->in('mypropery', null));

the querybuilder caches something like "... 1<>1 ..." under the same identifier as above.

This leeds to errors / empty results when the value of the constraint changes from null value to non null values or vice versa.
