Inside [Tuning for Disk Space](https://www.elastic.co/guide/en/elasticsearch/reference/current/tune-for-disk-usage.html) i have read something about index\_options parameter.
For my use case i currently have the default set. I have tried setting this parameter to "docs", which is not supposed to generate term freq and positional offsets.
I have seen below behaviors:
1. If i check /\_termvectors for my fields after setting to "docs". I can see "term\_freq", "position", "start\_offset", "end\_offset" values are generated 🙄
2. But while searching i observe that the above parameters are not considered in calculating score. This is ok and works as expected.
**Query:**
If all the values above are always generated (even though not used while searching), how is "docs" going to save space on disk or in memory ?
