The dotted field names are not being parsed when using do_complex_query

[Larcis]

Hi, When I try to use do_complex_query -> select kwarg like select='rtc_cm:x.y.z' I get lark.exceptions.UnexpectedCharacters error with message

No terminal matches '.' in the current parser context, at ... 
rtc_cm:x.y.z
        ^
Expected one of: 
         * COMMA 
         * LBRACE

Same select statement seems fine when using execute_oslc_query.
