Hello All, I would like to perform EXACT Match (Example Search : "Firstname Lastname") in a String field "ArticleBody" where the _value of the field is a big chunk of text_ and within in this text I would like to perform the exact match. I came across couple of links: [http://paulsabou.com/blog/2012/03/25/advanced-exact-matching-with-elastic-search/](http://paulsabou.com/blog/2012/03/25/advanced-exact-matching-with-elastic-search/) [http://gauth.fr/2012/08/exact-search-with-elasticsearch/](http://gauth.fr/2012/08/exact-search-with-elasticsearch/) which explains that if we change the mapping of the filed to "not\_analyzed", then the entire field value will be considered as one string and I understand that this will only work where the field values are 2-3 words and wanted to be considered as one single term. But in my case the Field "ArticleBody" will contain a very big chunk of text(I dont want to treat the entire body of the article as single string) and would like to find specific keywords(like: "Elastic Search", "Firstname Lastname") within this text. Can this be done ? Please shed some light on this. Many thanks in advance, Shannu. -- ---

There are a few ways to achieve what you want. First of all, all the concepts related to search stem from Lucene. You can learn more about searching in Elasticsearch, but reading about Lucene. Second, is case important to you? Your goal is to create an analyzer that creates tokens that helps you achieve your queries. This could entail not lowercasing, stemming, and removing stop words. Easiest way is using phrase queries: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/query-dsl/match-query.html) Make sure you use a correct analyzer. You can also using span queries with a slop of 0: > **[Elasticsearch Platform — Find real-time answers at scale](https://www.elastic.co)** > > Power insights and outcomes with the Elasticsearch Platform and AI.
