Searching for an Exact Email Address

[Kevin Foley]

Hi,

I'm getting unexpected results when trying to search for messages
associated with an email address.

An example search is:

$ notmuch search to:"example at email.com"

which is returning messages that seem to have nothing to do with the
address I'm looking for.

My understanding is this should be treated as a phrase which means that
exact phrase will be searched for, is this correct?  If not is there a
way to search for an exact email address in the to field?

Thanks,
Kevin
