titleHere's a loose grammar which defines the filter expressions:

Expr ::= Expr
Expr ::= '(' Expr ')'
Expr ::= '!' Expr
Expr ::= Expr LogOp Expr
LogOp ::= '&&' | '||'
Expr ::= Comparable CmpOp Comparable
CmpOp ::= '==' | '!=' | '>=' | '<='
Comparable ::= "String"                --> a String constant must be enclosed in double quotes
Comparable ::= Number
Comparable ::= Identifier
Comparable ::= UnOp Comparable
UnOp ::= '-' | '+'
Comparable ::= Comparable BinOp Comparable
BinOp ::= '/' | '*' | '+' | '-'
