OXYCORE_API ExprNode	parse (std::string_view input)
	Parse the input query string into an AST.

Detailed Description

Parse textual queries into an expression AST.

The parser supports:

• Dotted paths with quoted segments
• Operators: = (alias :), !=, <, <=, >, >=, like
• Value-level groups via parentheses with and/or/not
• Expression-level grouping with parentheses with and/or/not

On error, throws ParseError. On success, returns a valid ExprNode.

Note

The parser trims outer double quotes when the whole input is quoted; this matches typical shell usage where you pass "...query..." as one arg.
