Hello,  
I'm working on an existing code written in ruby (i guess it uses some elasticsearch gem). the elasticsearch version is 5.5.

I'm trying to understand what is going on in a specific part of the code.  
**can someone please help me understand?**

```
mapping dynamic: false do
  indexes :title, type: 'text', analyzer: "name" do
    indexes :partial, type: 'text', analyzer: "autocomplete",
    search_analyzer: "autocomplete_search"
  end
end

```

**does this mean title property has a child field called "partial"?**
