For tests over 1M document collection add versions of the queries for smaller collection sizes (100 and 10K documents).

We have wide $and and $or queries with many terms on a single level. In Genny:

MatchOrWithManyChildClausesTemplate: runs $or with 50, 100, and 200 clauses, 1M documents.

MatchAndWithManyChildClausesTemplate: runs $and with 50, 100, and 200 terms over the same array field, equalities, 1M documents.

There are few queries with DNF and mixed predicates, up to 3 levels, 1M documents:

MatchExpressionDeepPredicate

MatchExpressionMixedPredicate

Recently MatchWithLargeExpression added DNF queries with 2 levels and up to 50000 clauses, 10 documents.

There are several queries with $elemMatch:

MatchElemMatchObject: $or with 4 terms, 1M documents

MatchElemMatchObjectWide: $or with 28 terms, 1M documents
