I noticed that the problem usually happens when the number of results in the agg is rather small.

I have 5 shards on that index, and the aggs return 10 results (again, I'm not sure why not more when I request specifically as mentioned in item 1 in the OP.

it looks like when the agg value is less than 50 (5 shards * 10 aggs) I get this problem, so the aggs shows a smaller value than the actual hits returned.

is that a known issue?  any ideas on how I can get it to work properly?

I also posted to http://stackoverflow.com/questions/23254153/faceted-search-and-aggregations-do-not-work-properly since there was no much response here.

thanks,

    Thanks Nik -- that's what I was thinking too.

    I was wondering if someone from the ES team could confirm that my
    code is correct for what I'm trying to achieve.

    Sorry, wasn't reading too closely. If the execution:and is taking
    sometimes then that sounds like a bug.

    hey Nik,

    thanks for your reply.

    you are correct about the default operator being "or", but as
    I've posted in the original post I explicitly set it to "and"
    via "execution": "and" and I see the difference in the results
    between "or" and "and" so I know that it is working.  for some
    reason the numbers still do not match some of the time though.

        to the filter terms so that it reads "tags": [ "Colorful",
        "Yellow" ]I get 17 hits instead of the expected 12.

        If I recall the terms filter is an or filter. So you are
        getting colorful or yellow. It might have an and option. Not
        sure, on my phone now. Otherwise use a bool filter with two
        must subfilters to do an and.
