I'm trying to reindex a timebased index to apply a new template but after reindexing the doc count of the new indexes are much less than original, I'm using the task api so I might miss some errors, not sure, can't find info on how to get errors after task i complete.

here is what I do:

first reindex:  
POST \_reindex?wait\_for\_completion=false  
{  
"source": {  
"index": "someindex-2018.05.25"  
},  
"dest": {  
"index": "someindex"  
},  
"script": {  
"lang": "painless",  
"source": "ctx.\_index = 'someindex-' + (ctx.\_index.substring('someindex-'.length(), ctx.\_index.length())) + '-2'"  
}  
}

after task is finished:

GET someindex-2018.05.25-1/\_count -\> 171026

GET someindex-2018.05.25/\_count -\> 930835

trying a second time...

GET someindex-2018.05.25-2/\_count . -\> 79994

and a third time, same doc count as the second one. No errors in the logs.

What am I doing wrong here?
