In most cases you will use the client's `search()` method to accomplish this. + +==== Elasticsearch Query DSL + +For many searches you will want to define a search document that tells elasticsearch exactly how to find the documents you are looking for. To do this you will use the http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl.html[elasticsearch query DSL]. If you are not familiary with Elasticsearch's query DSL is it recommended that you research the topic at elasticsearch.org or watch/read one of these introductions: + + * https://www.youtube.com/watch?v=52G5ZzE0XpY#t=1471[Clinton Gormley "Getting down and dirty with Elasticsearch"] + * http://okfnlabs.org/blog/2013/07/01/elasticsearch-query-tutorial.html#query-dsl-overview[Querying Elasticsearch - A Tutorial and Guide] + * http://exploringelasticsearch.com/book/searching-data/the-query-dsl-and-the-search-api.html[The Query DSL and the Search API - Searching Data - Exploring Elasticsearch] + +Now for some examples using the Query DSL. + +===== Simple match query + +[source,js] +----------------- +// match tweets that have "elasticsearch" +// in their body field +client.search({ + index: 'twitter', + type: 'tweets', + body: { + query: { + match: { + body: 'elasticsearch' + } + } + } +}); +----------------- + +===== More complex filtered query + +To power a search form on a public site, you might want to allow the user to specify some text but also limit the documents returned by a few criteria.
