Hi everyone,

Today I noticed that for an index I'm currently reindexing (as source, all writes disabled only search taking place) there are some refreshes happening, but the refresh\_interval is already set to -1.

I see every time this happens the search QoS decreases dramatically, as soon as refresh finishes, it returns back to normal (450~ req/sec)

 ![refresh%20index%20unexpected](https://us1.discourse-cdn.com/elastic/original/3X/5/0/50a7b3f852713cccc795d2f66d195e63d5ea7e9e.png)

Is there any other setting that needs to be disabled in the index or cluster level so this kind of unexpected refresh cycles don't happen ?

With refresh interval set to -1 I believe refresh happens purely based on size when the internal buffers fill up.
