Hi all,
I am using solr-river plugin for migrating all the data from solr3.6 to
elastic search.
My solr instance contains 5 cores and have to migrate all the cores into
correspondinx indexes of elastic search.
I have migrated one core into elastic search using solr-river but the
problem is:
During migration elastic search creates one index with the name "solr" and
type "import"
1. I want to rename this index to some other name which i am unable to do.
2. I have know clue how can i migrate my all solr cores into different
indexes into elastic search.
Please help me in these issue..
Thanks in advance.

Hi,
I've never used this plugin, but looking at the
README[https://github.com/javanna/elasticsearch-river-solr/blob/master/README.md](https://github.com/javanna/elasticsearch-river-solr/blob/master/README.md)it
seems that you have an "index" option that lets you specify where to
index your data:
```
"index" : {
"index" : "solr",
"type" : "import",
"bulk_size" : 100,
"max_concurrent_bulk" : 10,
"mapping" : "",
"settings": ""
}
```
If you need to take one core at a time and put it in different places, I
guess you can use multiple rivers with multiple configurations. For example:
"url" : "[http://localhost:8983/solr/core1/](http://localhost:8983/solr/core1/)",
for one river and
"url" : "[http://localhost:8983/solr/core2](http://localhost:8983/solr/core2)",
for another and so on.
Best regards,
Radu

Yes Mr. Radu Gheorghe, you are absolutely correct. I had a chat with Mr.
Luca cavanna too and he pointed out the same thing.
There is one more issue i am facing and that is if i have to manipulate
some fields while migration (Some fields needs to be merged and some has to
be deleted) then how can i do that.
I know by specifying fields name which needs to be fetched in fl parameter
but i need to merge the value of some fields into a single one during
migration. If possible then reply how can i achieve that.
_Thanks for your time and valuable comment._
_Regards,_
_Bharvi Dixit_

I think you can achieve that by using scripting, although it might slow
down the import time. Have a look at the README, transform section in the
json, which allows to somehow modify your documents through scripting
before indexing them.
