Edge n-gram search for terms with optional spaces

Elastic Stack Elasticsearch
4

I got another insight from another thread here: Search by digits doesn't work with edge_ngram - #2 by dadoonet

I tried analyze and it is removing the numbers from my query. I replaced the tokenizer with "whitespace" instead

I also decided to have 2 fields: original and term, and keeping term.autocomplete as in the example. Both fields are searched with no boosting and it seems to work as expected now.
