Is there a way where we can **_ignore certain JSON keys_** inside a JSON dump while doing a `bulk` import in **elasticsearch**.

I'm currently working with Node JS. As mentioned in the below code, `data.json` contains certain `JSON keys` that I would want `elasticsearch` to ignore while importing. These keys can be of any type, example an Object, a string, a boolean, etc.

```
var bulkIndex = function bulkIndex(index, type, data) {
    let bulkBody = [];

    data.forEach(item => {
        bulkBody.push({
            index: {
                _index: index,
                _type: type,
                _id: item.id
            }
        });

        bulkBody.push(item);
    });

    esClient.bulk({
            body: bulkBody
        })
        .then(response => {
            let errorCount = 0;
            response.items.forEach(item => {
                if (item.index && item.index.error) {
                    console.log(++errorCount, item.index.error);
                }
            });
            console.log(`Successfully indexed ${data.length - errorCount} out of ${data.length} items`);
        })
        .catch(console.err);
};
const test = function test() {
    const rawJSON = fs.readFileSync('data.json');
    const processedJSON = JSON.parse(rawJSON);
    console.log(`${processedJSON.length} items parsed from data file`);
    bulkIndex('myIndex', 'myType', processedJSON);
};
test();
```

Can't you do that in your JS code?

Yes, that's what I'm going to do now. The JSON is basically Shopify's storefront product data. I've decided to use GraphQL and get specific fields only from the corresponding API.
