Hi

I have multiple indexes in my elastic search DB. I am trying to query one of the index among them but the query is failing and it is connecting to a differnt index rather than the one that i mentioned in the query.

The script is as below:

if [docname] {  
elasticsearch {  
hosts =\> ["[XYZ.com:9200/test-myo-docs/data](http://XYZ.com:9200/test-myo-docs/data)"]  
query =\> 'ddocname:%{docname}'  
fields =\> ["ddoctitle"]  
#We can any number of fields

```
                   sort => "ddoctitle:desc"
    }

```

The log output:

":"query\_shard\_exception","reason":"No mapping found for [ddoctitle] in order to sort on","index\_uuid":"kA0NmuwhSS2d9rf\_gpozFQ","index":" **token-prod-na-ucf-wls-2018.02.05**"}},{"shard":0,"index":"token-prod-na-ucf-wls-2018.02.06","node":"hdokW\_3gQFeowO0oKgOOrQ","reason":{"type":"query\_shard\_exception","reason":"No mapping found for [ddoctitle] in order to sort on","index\_uuid":"OlkNtnNMTTmQk3xU9Tp-qw","index":"token-prod-na-ucf-wls-2018.02.06"}},{"shard":0,"index":"token-prod-na-ucf-wls-2018.02.07","node":"hdokW\_3gQFeowO0oKgOOrQ","reason":{"type":"query\_shard\_exception","reason":"No mapping found for [ddoctitle] in order to sort on","index\_uuid":"2pWHJ5HRRLWFiDkMuKQg3w","index":"token-prod-na-ucf-wls-2018.02.07"}},{"shard":0,"index":"token-prod-na-ucf-wls-2018.02.08","node":"ubu7iS9YQ3aUHB-\_KWUqpw","reason":{"type":"query\_shard\_exception","reason":"No mapping found for [ddoctitle] in order to sort on","index\_uuid":"JPf9oL4fSh-OwMzRMlxodA","index":"token-prod-na-ucf-wls-2018.02.08"}},{"shard":0,"index":"token-prod-na-ucf-wls-2018.02.09","node":"hdokW\_3gQFeowO0oKgOOrQ","reason":{"type":"query\_shard\_exception","reason":"No mapping found for [ddoctitle] in order to sort on","index\_uuid":"Keq5vxzyQWuyaVtm0t9kQQ","index":"token-prod-na-ucf-wls-2018.02.09"}},{"shard":0,"index":"token-prod-na-ucf-wls-2018.02.10","node":"hdokW\_3gQFeowO0oKgOOrQ","reason":{"type":"query\_shard\_exception","reason":"No mapping found for [ddoctitle] in order to sort on","index\_uuid":"0IaimkzuQGanvMsyXhIbIg","index":"token-prod-na-ucf-wls-2018.02.10"}}]},"status":400}\>}

What is the reason behind this ? and how can I force the query to use the correct index?

Is it a logstash "Script"? What is that?

Yes. It is logstash script.

How can I write an exception for the no mapping.

Logstash log:  
type"=\>"query\_shard\_exception", "reason"=\>"No mapping found for [@timestamp] in order to sort on"

Is it the same question? You mentioned first something about `ddoctitle`.

I moved your question to #logstash
