Hello! MonetDB documentation says, that JSON is supported in MonetDB, but I can`t find any example. When I try to implement this query in MonetDB client: json.filter({ "store": { "bicycle": { "color": "red", "price": 19.95 }}},'$') I get this error: syntax error, unexpected IDENT in: "json" THX

Hi Art,
