Auto-labeling policy condition with document properties for sensitivity labels

Hi, is there a comprehensive documentation regarding the rules conditions using document properties? 

Valid search queries often does not work in auto-labeling conditions.... 

Questions:

- Are all default managed properties with predefined refinables can be used? (excluding custom properties)

- Can we use AND and OR in one line condition? : Path:xxxx AND Subject:XXXX

- Are double quotes supported in query or we need to encode (ex: url)?

- Multiline condition are evaluated as OR (Looks like it is) ?

Thanks.
