Indexes
|
|
==========================
|
|
|
|
Indexes refer to ways to structure documents so that LLMs can best interact with them.
|
|
This module contains utility functions for working with documents, different types of indexes, and then examples for using those indexes in chains.
|
|
LangChain provides common indices for working with data (most prominently support for vector databases).
|
|
For more complicated index structures, it is worth checking out `GPTIndex <https://gpt-index.readthedocs.io/en/latest/index.html>`_.

|
The following sections of documentation are provided:
|
|
|
|
- `Getting Started <./indexes/getting_started.html>`_: An overview of all the functionality LangChain provides for working with indexes.
|
|
|
|
- `Key Concepts <./indexes/key_concepts.html>`_: A conceptual guide going over the various concepts related to indexes and the tools needed to create them.
|
|
|
|
- `How-To Guides <./indexes/how_to_guides.html>`_: A collection of how-to guides. These highlight how to use all the relevant tools, the different types of vector databases, and how to use indexes in chains.
