When we write an application, we also write migrations for database schema and data, we use [liquibase](http://www.liquibase.org/) for that.

What tools/library are using for migrations ElasticSearch schema?

When I deploy an application on new server, everytime I must execute this query before application starts  
curl -XPUT 'localhost:9200/products?pretty' -H 'Content-Type: application/json' -d'  
{  
"mappings": {  
"doctype": {  
"properties": {  
"title": {  
"type": "text"  
}  
}  
},  
"queries": {  
"properties": {  
"query": {  
"type": "percolator"  
}  
}  
}  
}  
}'

So, i am asking is there a tool where I can put this schema and run this schema if application is first time running

Are you saying you are deploying to a new cluster? Or the same one?

Also we call schema's mappings 🙂

For example I am deploying an application locally as developer on my machine, application uses elasticsearch, but before adding some data I need to execute that query  
So, I want to add that query to some files, so, when another developer will deploy application on his machine, that query will be executed automatilly
