Description

Here is the screenshot of the operators and their types
![DeepinScreenshot_select-area_20200113133001](https://user-images.githubusercontent.com/25095884/72240016-d6d2d100-3608-11ea-8cab-5eb3db5ec7ba.png)

I have a string column which is nullable. It can contain `empty string` ~ "" , `null` and non-zero length string. I would like to run a query with `_in: ["", null]`. But its not allowed based on the schema.
