I am unable to find examples on the web. Is there any way to delete fields names that contains dots using logstash?  
My indices are failing the migration tool test, I am unable to upgrade to 2.2 yet. My plan is to re-index  
I need to delete fields as follow:  
"[http://xxxx.xxxxx.com/collect/](http://xxxx.xxxxx.com/collect/)" : {  
"type" : "string"  
},  
"facet.filter" : {  
"type" : "string"  
},  
"par\_id" : {  
"type" : "string",  
"index" : "not\_analyzed"  
},

Please help

You might be able to use the [de\_dot filter plugin](https://www.elastic.co/guide/en/logstash/current/plugins-filters-de_dot.html), which was designed as a migration aid. It will however not delete the field, but rename it.

Hi Christian  
The de\_dot plugin seems to be doing the job when I tested it with one index. I have 386 indices to re-index  
How can I do bulk re-indexing using with de\_dot? indices names follows the following patterns:  
index-2016.month.day eg. index-2016.03.01, index-2016.03.02, index-2016.03.03...etc...  
input {  
elasticsearch {  
hosts =\> ["cluster\_name.com:9200"]  
index =\> "index-2016.03.01"  
size =\> 500  
scroll =\> "5m"  
docinfo =\> true  
}  
}

output {  
elasticsearch {  
hosts =\> "remote\_cluster:9200"

```
	index => "index-2016.03.01"
}
```
