#### Post date: [April 16, 2015, 9:36am UTC](https://discuss.elastic.co/t/head-shows-incorrect-docs-count-if-nested-type-field-is-defined-in-mapping/23270/1 "2015-04-16T09:36:04Z")
I was confused by the docs count value displaying in head plugin if there
is nest type field define in mapping
For example, I created a new index with following mapping:
{
"mappings" : {
"doc" : {
"properties" : {
"QueryClicks" : {
"type" : "nested",
"properties" : {
"Count" : {
"type" : "long"
},
"Term" : {
"type" : "string"
}
}
},
"Title" : {
"type" : "string"
}
}
}
}
}
And then insert ONE doc:
{
"QueryClicks":[{"Term":"term1","Count":10},{"Term":"term2","Count":10}],
"Title":"test title"
}
Then refresh Head, the docs shown on Head is 3:
size: 3.57ki (6.97ki)
docs: 3 (3)
Why?

BTW: If I just remove the "type":"nested" from the mapping, the doc count
then is correct after insert one document.
Anyone has suggestions resolve this issue?

Just figured out that the doc count is actually the number of document +
the number of items of nested field, in my case, the QueryClicks field has
two items, then the total number of doc shown on head is 1+2=3.
But this might confuse the people who view doc counts on head or other UI
plug-in.
Is there anyway let head just show the doc count, regarding if the doc has
nested field or not.

Go to the "browser" tab and select the type. That will show the count you
are looking for.
