Elasticsearch multi_match + nested search - elasticsearch

Question

I am trying to execute a multi_match + nested search in ElasticSearch 6.4. I have the following mappings:
"name" : {
"type" : "text"
},
"status" : {
"type" : "short"
},
"user" : {
"type" : "nested",
"properties" : {
"first_name" : {
"type" : "text"
},
"last_name" : {
"type" : "text"
},
"pk" : {
"type" : "integer"
},
"profile" : {
"type" : "nested",
"properties" : {
"location" : {
"type" : "nested",
"properties" : {
"name" : {
"type" : "text",
"analyzer" : "html_strip"
}
}
}
}
}
}
},
And this is the html_strip analyzer:
"html_strip" : {
"filter" : [
"lowercase",
"stop",
"snowball"
],
"char_filter" : [
"html_strip"
],
"type" : "custom",
"tokenizer" : "standard"
}
And my current query is this one:
"query": {
"bool": {
"must": {
"multi_match": {
"query": 'Paris',
"fields": ['name', 'user.profile.location.name']
},
},
"filter": {
"term": {
"status": 1
}
}
}
}
Obviously searching for "Paris" in user.profile.location.name doesn't work. I was trying to adapt my code to following this answer https://stackoverflow.com/a/48836012/12007123 but without any success.
What I am basically trying to achieve, is to be able to search for a value in multiple fields, this may or may not be nested.
I was also checking this discussion https://discuss.elastic.co/t/multi-match-query-string-with-nested-and-non-nested-fields/118652/5 but everything I tried wasn't successful.
If I just search for name, the search is working fine.
Any tips on how can I achieve this the right way, would be much appreciated.
EDIT:
While I didn't get an answer to my initial question, I was following Nikolay's (#nikolay-vasiliev) comment and changed th mappings to Object instead of Nested.
At least now I am able to search in user.profile.location.name. This is how the new mapping for user looks like:
"user" : {
"properties" : {
"first_name" : {
"type" : "text"
},
"last_name" : {
"type" : "text"
},
"pk" : {
"type" : "integer"
},
"profile" : {
"properties" : {
"location" : {
"properties" : {
"name" : {
"type" : "text",
"analyzer" : "html_strip"
}
}
}
}
}
}
},
