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.
