Enabling typecast for model properties in filter object of query

Suggestion

I would like to see a option to typecast the model fields in filter object of find query, i.e in short I would like to run sql query equivalent to

Select * from feature where CAST(createdDate as date) > getdate()-4 order by createdDate

here type of createdDate field is string in database

Use Cases

This would be useful to execute queries by changing the type in runtime without modifying the database tables types.
Currently we can bypass this by running repository.execute() command but return type of this query is 'AnyObject' which not useful.

Examples

repository.find({castTo:['createdDate date'],order:['createdDate ASC'],where:{createdDate:{gt:addDays(new Date(),-4).toString()}}})
here castTo property can be used to typecast any filed to desired type

Acceptance criteria

TBD - will be filled by the team.

Start at the repository.find filter path and compare it with repository.execute, the entry points mentioned in the issue. Clarify the missing acceptance criteria with maintainers, including supported cast expressions and the expected result type; done requires an agreed design and tests for runtime field casting.
