Boosting exact matches in edgengram search

If I search for "liz" I need an exact match of "liz" to score higher than
"lizz"

Can I do this all in one query or do I need to run a separate query to look
for an exact match?

I would expect it to do this automatically, because "liz" has fewer tokens
than "lizz". However, to ensure that it works the way you want, you can
index the field as a multi-field, using (eg) the standard analyzer on the
main field, and your edge-ngrams on another field.

The use a bool query which matches against both fields - you'll find docs
that match the ngrams, but docs with exact matches will be boosted by the
clause on the main field.

Hi Clint,

We are encountering the same issue. This sounds like a bug. Should we file
a ticket against ES?

Thanks,

Bob

I was also expecting this to work without using multi-field. Am I missing something?

It's 2017, and I'm still have the same problem? Did anyone figure this out without using multi-field? Or is that the only way? I'd really love to know! Thanks in advance!
