Hi all!

I want to use my custom analyzer (autocomplete -- below) on a number field that I have indexed as shown below. I am using Ruby on Rails Elasticsearch version.

```auto
  settings index: {
     analysis: {
       filter: {
         autocomplete: {
           type: :edge_ngram,
           min_gram: 1,
           max_gram: 10, 
         }   
       },  
       analyzer: {
         autocomplete: {
           type: :custom,
           tokenizer: :standard,
           filter: %i[lowercase autocomplete]
         }   
       }   
     }   
  } 
do
    mappings dynamic: false do
      indexes :model, type: :text do
        indexes :model, type: :text, analyzer: :autocomplete
        indexes :model, type: :text, search_analyzer: :standard
      end 

       indexes :mpg, type: :text, analyzer: :english
   end
end

```

Now what I want to do is as the user types in the range of MPG they want in the search bar (have 2 fields -- so like 10 - 20 MPG), I want the autocomplete to be returning numbers automatically like my model field (i.e. 2 digits i.e. 7, 79, 80, 81 etc). However, I don't know if I can do this 3 analyzers on my MPG field? And if so, I don't know if a range can be specified on a field with a custom analyzer using edge\_ngrams? Any direction would be great.
