Can elasticsearch handle the indexing part if I change schema of data ? For example: My first data contains fields (name, age, address, company) then if I add a similar data with additional field like (name, age, address, company, country). Is this situation can be handled by elasticsearch ? Or to use elasticsearch the data should have same structure ? Kind regards, Haseb Ansari ---

In general you can add new fields at any time. In it's default configuration Elasticsearch will automatically index those fields. This is called [dynamic mapping](https://www.elastic.co/guide/en/elasticsearch/reference/2.2/dynamic-mapping.html). ---
