My concern isn't network usage, it's paging. Sometimes my result set is
quite large, and I want to only page into the results when necessary. If
missing docs are included in the response, I'm forced to fetch the whole
lot, in order to filter out missing docs client-side, so that I'm reporting
the correct document count to the client app.
If I can't do this currently and others agree this is a reasonable thing to
want to do, I'll open an issue.
thx

You can easily filter that on client side.
Is your concern about network usage?
May be you should open an issue to have an 'ignore_missing' option for
_mget API (default to false)?

Sorry I meant to show that example using mget:
]$ curl -XGET 'http://localhost:9200/fury/products/_mget' -d '{"ids":
["BAD_ID","GOOD_ID"]}'
{"docs":[{"_index":"fury","_type":"products","_id":"BAD_ID","exists":false},{"_index":"fury","_type":"products","_id":"GOOD_ID","foo":"bah","etc":"etcetc"}]}
What I want is this behaviour:
]$ curl -XGET 'http://localhost:9200/fury/products/_mget' -d '{"ids":
["BAD_ID", "GOOD_ID"]}'
{"docs":[{"_index":"fury","_type":"products","_id":"GOOD_ID","foo":"bah","etc":"etcetc"}]}

I want those nonexistent documents not to be returned in the result set

not exist in the database, and I don't know this ahead of time. I simply
want those nonexistent documents to be silently removed from the result
set. Is this possible?
"Back to your original need, what do you mean by needing "those with

Consider:
$ curl -XGET 'http://localhost:9200/idx/type/SOME_BAD_ID'
{"_index":"fury","_type":"products","_id":"ID0","exists":false}
I want a result set that does not include these exists=false docs at all.
thanks

But I can't seem to get this to work. I've tried something like this
(and various combinations), to no avail:
]$ curl -XGET 'http://localhost:9200/idx/**type/_mget?ignore_indices=**
missing http://localhost:9200/idx/type/_mget?ignore_indices=missing'
-d '{"ids": ["xxx"]}'
ignore_indices is only useful when you're using an index wildcard. For
example:
curl -s 'localhost:9200/foo*/_search?**ignore_indices=missing&size=1'
If no index matches the foo* pattern, you won't get an error. This would
have the same effect as searching the entire cluster.
In your case, you're not using a wildcard for the index name, but more
importantly, you're using mget which is only useful when you know exactly
the index/type/id triplet that will reference the docs you want.
Back to your original need, what do you mean by needing "those with
exists=false" to be omitted? You have a field called "exists" and want to
search where it has a true value?
