In Elasticsearch, when we index documents to an index, by default the source of the document is stored in meta field _source.
When you search your index, you see a special field _source for each matched/hit product.

In Elasticsearch, you can use wildcard in a lot of the index operations. This is very handy, but can be dangerous sometimes, e.g., when you use wildcards when deleting indexes. You may delete unintended indexes accidentally and cause serious interruptions to your business/work.
