Can the random number generated text be searchable in emails?

We use the random number generator on several of our forms but when the email comes in from Jotform we cannot search email for the random number. Is there a way to make it so when the email comes in the random number is searchable text as well?

I think it's possible. I tried searching for the random number and in my email and it does show up.

Hope this answers your question, but let us know if you have any questions or if you need further assistance. 

I don’t know if Gmail works differently than Outlook but when the emails come in through our Exchange server and we view the emails in Outlook we can search for any other part of the email but not the random number.
We don’t have the random number in the subject line either. Maybe that would help. I don’t remember seeing a way of putting the random number in the subject.

 I have tested to search for random number using my hotmail account and  the search works.

The random number is not in the subject line but it was still searched.

Hope this information helps.

Please let us know if you have further questions.
