+|useFilterCNF|`false`| If true, Druid will attempt to convert the query filter
to Conjunctive Normal Form (CNF). During query processing, columns can be
pre-filtered by intersecting the bitmap indexes of all values that match the
eligible filters, often greatly reducing the raw number of rows which need to

individual clauses of a top level 'and' filter. As such, filters in CNF
potentially have a higher chance to utiliz [...]
