[rt-users] wildcards in custom field searches

[gordon at cryologic.com]

I am currently performing a search on a custom field like so:

'CF.{Serial Numbers}' LIKE '655'

This obviously searches through the custom field "Serial Numbers".

Unfortunately information often gets put in the wrong place and locating 
it can be difficult.

Is it possible to use a wildcard (or other simple method) to search 
through all custom fields? For example:

'CF.{%}' LIKE '655'  (I tried this but it didn't work)

thanks
Gordon
