Searchable custom fields do not provide adequate operators
Using an integer custom field (called Affected revision, searchable) as a filter in the issues list should provide me with integer operators such as =, !=, >, <, >=, <=, ...
Instead, I am provided with string comparison operators which does not make much sense. It would also be interesting to be able to use range operator to determine a range of values. This is certainly required for both float and integer custom fields.
