Searching for Numbers in e-Mails

[eal]

Hello,

I have an e-Mail account set up, where the e-Mails from our orders will be delivered. In the subject line of the e-Mail is the order number written. For Example:

"Confirmation of your order 1234567"

When i now try to search through e-mails, for word Confirmation, i receive the mails back, that hold the keyword.

If i try to search for number 1234567 i allways receive no result back.

I'm working with Sugar CE 6.1.2

Does anyone of you have an idea or a trick to do that?

Am i really the only one that ist trying to do that?
