I'm running 1.1.1. I have found a few odd cases where the phrase suggester
with suggest\_mode: missing generates a suggestion even though the query
returns results. I am querying across two indexes (and two types), and in
the cases I have found, the query term only exists in one of the indexes.
When I re-run the query across just one of the indexes/types and then the
other, the suggester behaves as expected.
I am trying to come up with a curl recreation but I haven't been able to
reproduce it yet in a smaller corpus. Meanwhile, is it possible that there
is a bug in the suggester for suggest\_mode: missing where it incorrectly
judges that a term is missing from _all_ indexes in the query just because
it's missing from one index in the query?

Sure!
To get the phrase suggester to spit things out with smaller corpus try
setting the shards to 1 and set max\_term\_freq to .99 or something closer to
one the the default.

I am already using 1 shard per index, so the query is executing across 2
shards. I tried setting max\_term\_freq to 0.999 but was still unable to
reproduce it in a small corpus.
