Filter output of term facet - not input

I've read the elasticsearch api docs and done a lot of googling but still
cannot find a solution. I need to only output filtered items from the
faceted term search. So posting here.

Here is some sample data:
{
id: 1e27202c54a0a600e06257c0ae341e8e
interaction_type: bitly
url:
created_at: 2013-02-08T15:18:34.000Z
epoch: 1360336714000
tags: [
userid_5114575ae4b0cb71b6654320,
username_testuser1,
microsoft
]
geo_latitude: 51.900002
geo_longitude: 8.3833
geo_city: Gütersloh
geo_country_code: DE
geo_country: Germany
geo_region_code: 07
geo_region: Nordrhein-Westfalen
}
{
id: 1e27202c2e7aac00e062d233dde576aa
interaction_type: bitly
url:
created_at: 2013-02-08T15:18:28.000Z
epoch: 1360336708000
tags: [
userid_5114575ae4b0cb71b6654321,
username_testuser2,
kinect
]
geo_latitude: 23.051201
geo_longitude: 112.459702
geo_city: Zhaoqing
geo_country_code: CN
geo_country: China
geo_region_code: 30
geo_region: Guangdong
}

I want to find the number of occurrences for a bunch of user-ids for a
range of times. I came up with a filtered and faceted query like so:

{
"query": {
"range": {
"created_at": { "from": "now-10d", "to": "now"}
}
},
"from": 0,
"size": 0,
"facets": {
"tag_facet": {
"terms": {"field": "tags"},
"facet_filter": {
"or": [
{ "term": { "tags": "userid_5114575ae4b0cb71b6654321" } },
{ "term": { "tags": "userid_5114575ae4b0cb71b6654320" } }
]
}
}
}
}

The result I get is :

facets: {
tag_facet: {
_type: terms
missing: 0
total: 1947503
other: 305
terms: [
{term: username_testuser1,count: 539453}
{term: userid_5114575ae4b0cb71b6654320,count: 539453}
{term: iphone,count: 245888}
{term: microsoft,count: 193543}
{term: userid_50f06636e4b0560131c8730c,count: 107155}
{term: kinect,count: 101051}
]
}

The result I get also includes counts for other tags like username_testuser1,
microsoft, kinect etc. I dont want those results, only the counts for x
number of user-ids using [or] filters, where I will limit x to not more
than 10.

Any guidance on how to solve this? There could be 1000s of results and I
dont want to iterate through them in the app layer to find the two items
that are needed.

Thanks!

The facet filters will filter out which results to facet on, not filter out
the facets that are returned.

In your example, your first document has
tags: [
userid_5114575ae4b0cb71b6654320,
username_testuser1,
microsoft
]

Since this document passed the filter, all those values will be used for
the facet. You would need to iterate through them in the app layer.

Oh well. I had a feeling it couldn't be done. Thanks for verifying my
thoughts.

Maybe I am missing something but why not add filter on user to your query then you will limit your resultset and facets will only have the user you want

Actually you have two options:

  1. Use you can exclude tags you don't want counted (ie. microsoft,
    kinect, etc)
  2. Use a regex pattern for the terms you want included.

#2 would be my choice because it looks like you can do a basic
expression such as "username_.*$" or even looking for your specific
users "userid_5114575ae4b0cb71b6654321|userid_5114575ae4b0cb71b6654320"

See the section on excluding terms and regex patterns here:

Hope this helps.

Matt, thank you very much for the regex suggestion. It is awesome. This is
a sample of my resulted query. I think providing both a query filter and
facet filter might be overkill so I might remove it, but it works:

{
"size" : 0,
"query" : {
"filtered" : {
"query" : {
"bool" : {
"must" : {
"range" : {"created_at" : {"from" : "now-30d","to" : "now",
"include_lower" : true,
"include_upper" : true
}
}
}
}
},
"filter" : {
"or" : {
"filters" : [ {"term" : {"tags" :
"userid_50fd9f5373e13056e76f9e7f"}},
{"term" : {"tags" : "userid_51007ef3e4b0a99e8714a9e9"}},
{"term" : {"tags" : "userid_50e228cae4b05800e6ea1ef2"}},
{"term" : {"tags" : "userid_50fdaee7e4b05ced2d76710e"}},
{"term" : {"tags" : "userid_50c6dfdee4b030a63367a6e7"}},
{"term" : {"tags" : "userid_50f4680ce4b080e3535795dc"}},

{"term" : {"tags" : "userid_50f06636e4b0560131c8730c" }} ]
}
}
}
},
"fields" : [ "id", "tags" ],
"facets" : {
"usageFacet" : {
"terms" : {
"field" : "tags",
"size" : 9,
"regex" : "userid_.*$"
},
"facet_filter" : {
"or" : {
"filters" : [ {"term" : {"tags" :
"userid_50fd9f5373e13056e76f9e7f"}},
{"term" : {"tags" : "userid_51007ef3e4b0a99e8714a9e9"}},
{"term" : {"tags" : "userid_50e228cae4b05800e6ea1ef2"}},
{"term" : {"tags" : "userid_50fdaee7e4b05ced2d76710e"}},
{"term" : {"tags" : "userid_50c6dfdee4b030a63367a6e7"}},
{"term" : {"tags" : "userid_50f4680ce4b080e3535795dc"}},
{"term" : {"tags" : "userid_50ddf00ae4b000084a2dc057"}},
{"term" : { "tags" : "userid_50c6e080e4b030a63367a6e9" }},
{"term" : {"tags" : "userid_50f06636e4b0560131c8730c" }} ]
}
}
}
}
}

Another option could have been to use the query facet. But this one serves
better.

Yea, lose the facet filter. Move it up as another "must" clause to
your boolean query filter and don't use an "or" filter, use a
TermsFilter as that will give you better performance.

Matt, thank you very much for the regex suggestion. It is awesome. This
is a
sample of my resulted query. I think providing both a query filter and
facet
filter might be overkill so I might remove it, but it works:

{
"size" : 0,
"query" : {
"filtered" : {
"query" : {
"bool" : {
"must" : {
"range" : {"created_at" : {"from" : "now-30d","to" : "now",
"include_lower" : true,
"include_upper" : true
}
}
}
}
},
"filter" : {
"or" : {
"filters" : [ {"term" : {"tags" :
"userid_50fd9f5373e13056e76f9e7f"}},
{"term" : {"tags" : "userid_51007ef3e4b0a99e8714a9e9"}},
{"term" : {"tags" : "userid_50e228cae4b05800e6ea1ef2"}},
{"term" : {"tags" : "userid_50fdaee7e4b05ced2d76710e"}},
{"term" : {"tags" : "userid_50c6dfdee4b030a63367a6e7"}},
{"term" : {"tags" : "userid_50f4680ce4b080e3535795dc"}},
{"term" : {"tags" : "userid_50ddf00ae4b000084a2dc057"}},
{"term" : { "tags" : "userid_50c6e080e4b030a63367a6e9" }},
{"term" : {"tags" : "userid_50f06636e4b0560131c8730c" }} ]
}
}
}
},
"fields" : [ "id", "tags" ],
"facets" : {
"usageFacet" : {
"terms" : {
"field" : "tags",
"size" : 9,
"regex" : "userid_.*$"
},
"facet_filter" : {
"or" : {
"filters" : [ {"term" : {"tags" :
"userid_50fd9f5373e13056e76f9e7f"}},
{"term" : {"tags" : "userid_51007ef3e4b0a99e8714a9e9"}},
{"term" : {"tags" : "userid_50e228cae4b05800e6ea1ef2"}},
{"term" : {"tags" : "userid_50fdaee7e4b05ced2d76710e"}},
{"term" : {"tags" : "userid_50c6dfdee4b030a63367a6e7"}},
{"term" : {"tags" : "userid_50f4680ce4b080e3535795dc"}},
{"term" : {"tags" : "userid_50ddf00ae4b000084a2dc057"}},
{"term" : { "tags" : "userid_50c6e080e4b030a63367a6e9" }},
{"term" : {"tags" : "userid_50f06636e4b0560131c8730c" }} ]
}
}
}
}
}

Another option could have been to use the query facet. But this one
serves
better.
The query facet is available at :

Actually you have two options:

  1. Use you can exclude tags you don't want counted (ie. microsoft,
    kinect, etc)
  2. Use a regex pattern for the terms you want included.

#2 would be my choice because it looks like you can do a basic
expression such as "username_.*$" or even looking for your specific
users "userid_5114575ae4b0cb71b6654321|userid_5114575ae4b0cb71b6654320"

See the section on excluding terms and regex patterns here:

Hope this helps.

Thanks,

Maybe I am missing something but why not add filter on user to your
query then you will limit your resultset and facets will only have
the user
