public bool validateFilters;

Description

Boolean indicating if filters should be validated. Default is false.

If true and skipUnknownFilters is false, unknown filters will generate errors if no default handler is provided with QueryEngine.SetDefaultFilter.

        queryEngine.SetSearchDataCallback(myObj => new[] { myObj.id.ToString(), myObj.name });

        var query = queryEngine.Parse("id>10");
        Debug.Assert(query.valid, $"Query \"{query.text}\" should be valid.");

        // Because the QueryEngine doesn't validate filters, no other filters will generate an error when parsed.
