The server documents certain regex modifiers it supports: imxs
https://docs.mongodb.com/manual/reference/operator/query/regex/#op._S_options
It is actually inconsistent within itself of which options it supports:
gim: https://github.com/mongodb/mongo/blob/r3.4.0-rc3/src/mongo/bson/bsonelement.cpp#L245-L264
imxs: https://github.com/mongodb/mongo/blob/r3.4.0-rc3/src/mongo/db/matcher/expression_leaf.cpp#L232-L244
These modifiers are inconsistent with BSON Regex modifiers: imxlsu
http://bsonspec.org/spec.html
The shell however only allows and supports: gimy
https://github.com/mongodb/mongo/blob/r3.4.0-rc3/src/third_party/mozjs-45/extract/js/src/vm/RegExpObject.cpp#L933-L955
The server tools allow and support yet another set: gims
https://github.com/mongodb/mongo/blob/r3.4.0-rc3/src/mongo/gotools/common/bsonutil/bsonutil.go#L282-L287
