Finding duplicate documents or its count based on some field names

narinder_izap · December 28, 2013, 5:16am

Hi All,

    I need to know, if Elasticsearch has some feature to find the

duplicate documents or documents counts if I want to see how many documents
are having same values against two or more fields. I can do that for one
field using facets, but what if I need to do it against more than one
field. For Example : Suppose I have following doc in Es

doc 1 :

{
name : abc
age:22
country:usa
gender:male
}

doc 2 :

{
name:xyz
age:27
country:usa
gender:male
}

doc 3:

{
name:xyz
age:22
country:india
gender:female
}

doc 4
{
name:abc
age:22
country:usa
gender:female
}

So now my requirement is to find all doc having same age and same country,
So that doc1 and doc4 are duplicate for me, OR In simple words, I want
to have unique clause on a single fields or composite fields key. Is this
possible??

Please let me know if its possible using Elasticsearch, as I think it is
very important feature for me.

If you can use 1.0.0.Beta2, aggregations might be a solution.

Demo:

gist.github.com

https://gist.github.com/jprante/8159379

aggs.sh


curl -XDELETE 'localhost:9200/test'

curl -XPUT 'localhost:9200/test' -d '
{
    "mappings" : {
       "_default_": {
           "properties" : {
               "name" : { "type" : "string" },
               "age" : { "type" : "integer" },

More Like This could work, especially if using non-analyzed fields:

Hey,

another very simple solution could be a terms facet, using a script field,
which simply concatenates the two fields you want to check for. See
