How to reset or change Rollup-job’s indexer’s time

[darkwarrior (Amey)]

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.
