Questions tagged [elasticsearch-dsl-py]

Elasticsearch DSL is a high-level Python library whose aim is to help with writing and running queries against Elasticsearch.

It provides a more convenient and idiomatic way to write and manipulate queries. It stays close to the Elasticsearch JSON DSL, mirroring its terminology and structure. It exposes the whole range of the DSL from Python either directly using defined classes or a queryset-like expressions.

It also provides an optional wrapper for working with documents as Python objects: defining mappings, retrieving and saving documents, wrapping the document data in user-defined classes.
