About Search Toolkit

Search Toolkit is Mistral's open-source Python framework for building production RAG search pipelines. It handles document ingestion, OCR extraction, text splitting, embedding, and retrieval with built-in support for Vespa search and enterprise workflows.

Key Features

**Document Extraction.** Supports multiple file types including PDF, DOCX, PPTX, HTML, and audio files with built-in OCR and transcription extractors for processing scanned documents and converting speech to text.
**Text Processing Pipeline.** Includes text splitters, chunk enrichers, and embedders that prepare documents for semantic search by breaking content into optimized chunks and generating vector representations.
**Vespa Search Integration.** Native integration with Vespa search engine for scalable document indexing and retrieval, with application management tools for deploying and managing search infrastructure.
**Production-Ready Architecture.** Built for enterprise use with support for batch processing, observability tools, and workflow orchestration to handle large-scale document processing reliably.
**Multimodal Support.** Processes text, images, and audio through specialized extractors including Mistral OCR for visual content and Voxtral for audio transcription with speaker diarization.
**Open Source Framework.** Available as a Python library that developers can customize and extend, with full control over the ingestion and retrieval pipeline for building custom RAG applications.

Frequently Asked Questions

Search Toolkit is used to build production search and RAG pipelines. It handles the complete workflow from document ingestion and extraction to embedding and retrieval. Companies like CMA CGM use Search Toolkit alongside Voxtral to process audio from multiple sources and return alerts within 15 seconds.

Yes, Search Toolkit is an open-source Python framework that you can use and customize. However, some features like Mistral OCR extraction and embedding models require a Mistral API key and are billed based on usage through the Mistral API pricing.

Search Toolkit supports PDF, DOCX, PPTX, ODT, HTML, plain text, and audio files. It includes specialized extractors for each type, with OCR for scanned documents, HTML parsing that strips boilerplate, and audio transcription with speaker diarization.

Search Toolkit is designed for developers and data scientists building RAG applications or enterprise search systems. It's particularly useful for teams that need full control over their document processing pipeline and want to deploy production-grade search infrastructure.
