$in operator fails if document field name is "query"
count and find inconsistent when using $not and a regex
"Query" as a property name is allowed, however querying on it is not possible
the query for collection with "query" field didn't work as expected
Interpret $query as special so you can copy profiler/logged queries into shell
shell supports "query" works as a meta-operator - only "$query" should be supported
Document behavior of using the field name "query" as a find predicate
