match_all | macro for rust | Reflection library

I know that we can use projection in Elastic Search to influence which fields of the document are returned or not - similar to projection in other areas. However, can I also do a projection in such a way that fields - or for my case more importantly array elements - are filtered out if they do not meet a certain condition?

Let's say the documents indexed in ES look like this:

I am using Elasticsearch 7.12.0 , Logstash 7.12.0, Kibana 7.12.0 on Windows 10 x64. Logstash config file logistics.conf

From an Elasticsearch query I'd like to retrieve all the points within a variable distance. Let say I have 2 shops, one is willing to deliver at maximum 3 km and the other one at maximum 5 km:

I went through the following links before pasting the ques

Elasticsearch has_child returning no results

ElasticSearch 7.3 has_parent/has_child don't return any hits

ES documentation

I created a simple mapping with text_doc as the parent and flag_doc as the child.

I am currently working on a search engine and i've started to implement semantic search. I use open distro version of elastic and my mapping look like this for the moment :

curl -XDELETE "http://localhost:9200/index-consumo_react_mysql/_doc/_query" -d '{"query": {"match_all": {}}}'

error:

{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}

I am wanting to get all the logs from elasticsearch from a asp.net core web api application using NEST. I created a controller named ESController to get the logs that are in elasticsearch. However, when I do so, on swagger it only displays the first log and not the entire list of logs. I even wrote to the console to see if I can view those logs there as well but it does not display. I do not have a model class for the logs. Is there something wrong I am doing to retrieve/extract the logs from elasticsearch in the .net application?

Console displays: "Valid NEST response built from a successful (200) low level call on POST: /elastic-search-app-logs%2A/_search?typed_keys=true"

swagger:

Correct me if I am wrong, but in the ElasticSearch CLI running the command below will display the logs from elasticsearch:

I have a query which gives me the results I want, but I need to filter further so that only records MISSING a specific bucket are shown.

My query is this:

The search is pointing to an alias. The indexing process create a new index every 5 minutes. Then the alias is updated, pointing to the new index. The index is recreated to avoid sync problems that can occur if we update item by item when a change is made.

However, I need to keep track of the searched terms to produce a dashboard to list the most searched terms in a period. Or even using Kibana to show/extract it.

*The searched terms can be multi words, such as "white", "white summer night", etc. We are looking to rank the term, not the individual words.

I don't have experience with Elasticsearch and the searches that I have tried did not bring relevant solutions.

Thanks for the help!
