Hello,

1. We are doing rollup on our production indices which contains a large number of documents.
2. So the rollup-job is running from **August 2018 till todays date.**
3. And we create indices on daily basis like **index-20180801** , **index-20180802** , .....
4. But the problem we are facing right now is that some of our indices contains wrong data, and coz of that our rollup-index also contains the wrong data.
5. So we want to delete the wrong data documents from rollup index for eg. (say we have wrong data in rollup-index from **Jan 2019** to **May 2019** and we will delete this data) but the problem here is our rollup-job's indexer is now waiting at **10 May 2019** and after deleting **Jan 2019 to May 2019** data from rollup index we want to **reset the indexer's time** to **1 Jan 2019**.
6. So that the indexer can rollup correct data again for the period **Jan 2019 to May 2019** and so on..... and we dont have to delete and restart the rollup-job for this change.
7. I have checked some of the documentation pages and did some digging on internet but did not find anything.
8. Thanks in advance.
