Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited scalability for large datasets

   Performance degrades significantly with larger document collections due to its reliance on in-memory processing.

2. 02

   Complex setup and configuration

   Requires manual installation of dependencies, including specific versions of Python packages and external libraries like spaCy.

3. 03

   Poor documentation for advanced use cases

   Documentation is sparse on fine-tuning models and customizing the retrieval pipeline beyond basic usage scenarios.

4. 04

   Dependency on Wikipedia as a knowledge base

   Limited to information available in Wikipedia, which may not cover niche or specialized domains comprehensively.

What it does well

• Uses Wikipedia as a knowledge base for answering questions.

• Includes pre-trained models and scripts for training custom models.

• Supports document retrieval and passage ranking.
