elastic/elasticsearch-dsl-py
Elasticsearch Dsl Py
elasticsearch-dsl-py is a Python library for search integration that enables the construction of complex queries and the management of indices through a programmatic interface. It connects Python applications to a distributed search engine to implement advanced filtering and structured data retrieval.
The library employs an object-relational mapping pattern and a declarative schema definition to synchronize data structures using Python classes. It utilizes a fluent interface query builder with method chaining to incrementally construct search requests, which are lazily evaluated and serialized into JSON payloads.
The toolset covers high-level index management and the construction of search queries, allowing for the configuration of data indices and the retrieval of specific documents without the need to write raw JSON strings.
Features
- Search Query Construction - Enables the construction of complex Elasticsearch queries using Python objects instead of raw JSON.
- Fluent Query Builders - Implements a chainable, functional interface for constructing complex search queries.
- Object-Relational Mapping - Maps Python class definitions to search index schemas for structured data management.
- Search Index Schemas - Provides a declarative way to define search index mappings and settings using Python classes.
- Search Engine Integrations - Connects Python applications to Elasticsearch clusters to implement advanced searching and filtering.
- Search Index Management - Offers tools for configuring and maintaining Elasticsearch indices through a programmatic interface.
- Complex Search Querying - Constructs complex search queries using structured objects to simplify data retrieval without raw strings.
- Index Management - Provides a high-level interface to create and configure data indices for faster retrieval.
- Data Retrieval Interfaces - Implements precise programmatic interfaces to fetch structured documents from a distributed search engine.
- JSON Request Serializers - Automatically serializes structured Python object hierarchies into JSON payloads for API delivery.
- Lazy Query Execution - Defines search criteria as objects that defer API requests until results are explicitly accessed.
- Database Clients - High-level client for Elasticsearch.
- Search Tools - High-level client for search engines.
