Searching For Just Numbers in Outlook Emails

I was searching in Outlook 2010 for an email that contained an IP address. I went to my inbox and clicked in the search field and typed in part of the address and clicked the magnifying glass to search. No results. WTF? I knew I had several emails that had the numbers present, but Outlook didn’t see them. I then did an Advanced Search and included the Body. Still no results. I did an online search about this problem and found others that were having the same issue. Apparently Outlook cannot find just numbers without following specific steps. Here they are:

1. Click in the search field.
2. Click Search Tools on the toolbar.
3. Click Advanced Find.
4. Specify in the dropdown, Frequently Used Text Fields

THEN Outlook will find the numbers.
