I have a user document which contains many tags
Here is the mapping:
{
"user" : {
"properties" : {
"tags" : {
"type" : "nested",
"properties" : {
"id" : {
"type" : "string",
"index" : "not_analyzed",
"store" : "yes"
},
"current" : {
"type" : "boolean"
},
"type" : {
"type" : "string"
},
"value" : {
"type" : "multi_field",
"fields" : {
"value" : {
"type" : "string",
"analyzer" : "name_analyzer"
},
"value_untouched" : {
"type" : "string",
"index" : "not_analyzed",
"include_in_all" : false
}
}
}
}
}
}
}
}
Here are the sample user documents

User 3
{

"tags": [
{

Using the above ES documents for search, I want to construct a query where
I need to fetch users who have company tags in nested tag documents or the
users who do not have any company tags. What will be my search query?
For example in above case, if search for google tag, then the returned
documents should be 'user 1' and 'user 3' (as user 1 has company tag google
and user 3 has no company tag). User 2 is not returned as it has a company
tag other than google too.
