Search behaviour within Records for integers

Hi Guys,
Is it correct that if a field referenced in the title of a record listview is of type integer then pattern match on search doesnt work?

eg if there is a field which contains 123456 then any partial searches of 123 or 45 etc will not work but a full search of 123456 works.

Before I go to the effort of changing/ casting the fields in question (as the datasets are large so i'd rather not have any unnecessary overhead), is that out of the box behaviour or a bug that we're aware of?

Cheers,
Chris
