Database dependent case sensitivity when filtering
If this setting is active, the database will be case sensitive. When the
setting is not active, the filter will function independent of upper or
lowercase spelling, meaning that an entry of "a" will create hits that
contain a lowercase "a", but also hits with an uppercase "A".
