# Elasticsearch mapping config synchronization

## Description

There is a synchronization issue between the production Elasticsearch "schema" and the test (local) environment "schema". To synchronize both "schemes", a rake task`es:dump_mapping`was created in oma-models repo.

`es:dump_mapping`rake tasks fetches specified mapping config data for a specified index from a specified host:port.

## Usage

```
cd oma-models
rake es:dump_mapping`
```

$ rake es:dump_mapping
