Term Query on Keyword type which is part of a completion context did not work

Welcome!

It sounds like that your request actually returns 100 hits:

"total": {
  "value": 100,
  "relation": "eq"
},

What makes you think that it does not work?

Could you provide a full recreation script as described in About the Elasticsearch category. It will help to better understand what you are doing. Please, try to keep the example as simple as possible.

A full reproduction script will help readers to understand, reproduce and if needed fix your problem.
