Searching the index

Elasticsearch has a flexible search interface; it allows you to search across multiple indexes and types, or limited to a specific index and/or type.

We will go over both these approaches in this section.

curl -XGET 'http://localhost:9200/news,news2/article/_search?q=monday'

curl -XGET 'http://localhost:9200/news/article,article2/_search?q=monday'

curl -XGET 'http://localhost:9200/news/_search?q=monday' ...
