[Boolean](https://www.booleanapp.com/) would like to announce elastic-muto, a npm module for building elasticsearch queries using an easy and expressive syntax. The generated query can be customised as well!

### Code Example

```auto
// Import the library
const muto = require('elastic-muto');

// muto.parse returns an elastic-builder BoolQuery object
const qry = muto.parse('["elasticsearch"] == "awesome" and ["unicorn"] exists');
qry.toJSON();
{
  "bool": {
    "must": [
      {
        "term": { "elasticsearch.keyword": "awesome" }
      },
      {
        "exists": { "field": "unicorn" }
      }
    ]
  }
}

```

The parser was originally developed for parsing filter conditions for the [GET score API](https://www.booleanapp.com/docs/v1_score.html) of Boolean.
