The terminology we use at my company is you want to *gate* the effect of
boost to only very precise scenarios. A lot of this depends on how your
Email and Phone numbers are being tokenized/analyzed (ie what analyzer is
on the field type), because you really only want to boost when you have
high confidence email/phone number matches. You may actually have more of a
matching problem than a relevance problem. You can debug this in the Solr
analysis screen.
Another tool you can use is putting a mm on just the boost query. This
gates that specific boost based on how many query terms match that field.
It's good for doing a kind of poor-man's entity recognition (how much does
the query correspond to one kind of entity)
Something like
bq={!edismax mm=80% qf=Email^100 v=$q} <--Boost emails only when there's a
strong match, 80% of query terms match the email
alongside your main qf with the combined field
qf=text_all
There's a lot of strategies, and it usually involves a combination of query
and analysis work (and lots of good test data to prove your approach works)
(shameless plug is we cover a lot of this in Solr relevance training

Hope that helps
