Introduction
editIntroduction
editYou’ve reached the documentation page for Elasticsearch.Net and NEST, The two official .NET clients for Elasticsearch.
Why two clients?
editElasticsearch.Net is a very low level, dependency free, client that has no opinions about how you build and represent your requests and responses. It has abstracted
enough so that all the Elasticsearch API endpoints are represented as methods but not too much to get in the way of how you want to build
your json/request/response objects. It also comes with built in, configurable/overridable, cluster failover retry mechanisms. Elasticsearch is elastic so why not your client?
NEST is a high level client that has the advantage of having mapped all the request and response objects,
comes with a strongly typed query DSL that maps 1 to 1 with the Elasticsearch query DSL, and takes advantage of specific .NET features such as
covariant results and auto mapping of POCOs. NEST internally uses and still exposes the low level Elasticsearch.Net client.
Please read the getting started guide for both Elasticsearch.Net and NEST.
Questions, bugs, comments, requests
editAll of these are more then welcome on the github issues pages! We try to at least reply within the same day.
We also monitor question tagged with nest on stackoverflow or elasticsearch-net on stackoverflow, as well as discussions on our discourse site
