Refer to the [Installation section](https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/getting-started-python.html#_installation) of the getting started documentation. ## Connecting Refer to the [Connecting section](https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/getting-started-python.html#_connecting) of the getting started documentation. ## Usage ----- * [Creating an index](https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/getting-started-python.html#_creating_an_index) * [Indexing a document](https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/getting-started-python.html#_indexing_documents) * [Getting documents](https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/getting-started-python.html#_getting_documents) * [Searching documents](https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/getting-started-python.html#_searching_documents) * [Updating documents](https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/getting-started-python.html#_updating_documents) * [Deleting documents](https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/getting-started-python.html#_deleting_documents) * [Deleting an index](https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/getting-started-python.html#_deleting_an_index) ## Compatibility Language clients are forward compatible; meaning that the clients support communicating with greater or equal minor versions of Elasticsearch without breaking. It does not mean that the clients automatically support new features of newer Elasticsearch versions; it is only possible after a release of a new client version. For example, a 8.12 client version won't automatically support the new features of the 8.13 version of Elasticsearch, the 8.13 client version is required for that. Elasticsearch language clients are only backwards compatible with default distributions and without guarantees made. | Elasticsearch Version | Elasticsearch-Python Branch | Supported | | --------------------- | ------------------------ | --------- | | main | main | | | 8.x | 8.x | 8.x | | 7.x | 7.x | 7.17 | If you have a need to have multiple versions installed at the same time older versions are also released as ``elasticsearch7`` and ``elasticsearch8``. ## Documentation Documentation for the client is [available on elastic.co] and [Read the Docs]. [available on elastic.co]: https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/index.html [Read the Docs]: https://elasticsearch-py.readthedocs.io ## Feedback 🗣️ The engineering team here at Elastic is looking for developers to participate in research and feedback sessions to learn more about how you use our Python client and what improvements we can make to their design and your workflow. If you're interested in sharing your insights into developer experience and language client design, please fill out this [short form]. Depending on the number of responses we get, we may either contact you for a 1:1 conversation or a focus group with other developers who use the same client. Thank you in advance - your feedback is crucial to improving the user experience for all Elasticsearch developers!
