Issue with Parsing Field Names Containing Hyphens

[RahafTahayneh]

Description:
There appears to be an issue with the liqe parser when handling field names that contain hyphens (-). When field names with hyphens are used in search queries, the parser returns syntax errors.

Steps to Reproduce:
Use the following search query in a liqe-based application:

const filter = "attrs.user-id:12345";
const ast = parse(filter);

The parser throws a SyntaxError
