![]() ![]() You can read about the various string parameters you can add to the cat commands here. The idea is to return data in a more user-friendly format as opposed to the normal JSON response. I personally love the cat API and use it whenever possible. 'localhost:9200/indexname/_mapping/user?pretty' Mapping Management Add a new type to existing mapping "localhost:9200/indextoroll/_rollover/newindex" "localhost:9200/_resolve/index/indexname" "localhost:9200/indexname/_clone/clonedindex" "localhost:9200/indexname/_split/split-indexname" For example, you can use this API to create or delete a new index, check if a specific index exists or not, and define new mapping for an index. ![]() This type of Elasticsearch API allows users to manage indices, mappings, and templates. 'localhost:9200/my_index/my_type/_count?q=field: The Search API sometimes depends on usage of the Mustache language, which is implemented within Elasticsearch as a scripting language. Responses will contain matches to the specific query. Search APIs can be applied globally, across all available indices and types, or more specifically within an index. Update by query – the parameter at the end tells the query to proceed in the event there is a conflict between versions of a documentĪs its name implies, these API calls can be used to query indexed data for specific information. "localhost:9200/index1/_delete_by_query?pretty" Multi get API ( mget) – This lets you pull documents from multiple indices, specifying as many docs as necessary per indexīulk – This lets you perform multiple types of requests at once. Reindex – Copies a document from one index to another Get – Retrieve a specific existing document 'localhost:9200/twitter/my_index/my_type/1?pretty' ![]() The APIs detailed below are for handling single documents, but you can also make use of certain multi-document APIs for performing bulk actions (e.g. Using these APIs, for example, you will create documents in an index, update them, move them to another index, or remove them. This category of APIs are used for handling documents in Elasticsearch. Advanced users might find this cheat sheet we put together helpful as it contains some useful tips and best practices on the Elasticsearch Cluster API. This is by no means a full API guide - this would be impossible and is covered in Elastic’s official documentation. The API examples detailed below are Document API, Search API, Indices API, cat API and Cluster API. This article will try and provide an overview of the main API calls that you should get acquainted with as you get started with Elasticsearch, and will add some usage examples and corresponding cURL commands. ![]()
