About RSQL/FIQL

RSQL is a query language for REST APIs. It’s based on FIQL (Feed Item Query Language) – an URI-friendly syntax for expressing filters across the entries in an Atom Feed. FIQL is great for use in URI's. there are no unsafe characters, so URL encoding is not required. On the other side, FIQL’s syntax is not very intuitive and URL encoding isn't necessarily a bad thing, so RSQL also provides a friendlier syntax for logical operators and some of the comparison operators.
