The Apache Lucene™ project develops open-source search software. The project releases a core search library, named Lucene™ core, as well as PyLucene, a python binding for Lucene. Lucene Core is a Java library providing powerful indexing and search features, as well as spellchecking, hit highlighting and advanced analysis/tokenization capabilities. The PyLucene sub project provides Python bindings for Lucene Core. The Apache Software Foundation provides support for the Apache community of open-source software projects. Apache Lucene is distributed under a commercially friendly Apache Software license. Apache Lucene set the standard for search and indexing performance. Lucene is the search core of both Apache Solr™ and Elasticsearch™. Our core algorithms along with the Solr search server power applications the world over, ranging from mobile devices to sites like Twitter, Apple and Wikipedia. The goal of Apache Lucene is to provide world class search capabilities.

Objective is a multimodal search API that works for you, not the other way around. Objective understands your data & your users, enabling natural and relevant results. Even when your data is inconsistent or incomplete. Objective understands human language, and ‘sees’ inside images. Your web & mobile app search can understand what users mean, and even relate that to the meaning it sees in images. Objective understands the relationships between huge text articles and the parts of content in each, letting you build context-rich text search experiences. Best-in-class search comes from layering all the best search techniques. It’s not about any single approach. It’s about a curated, tight top-to-bottom integration of all the best search & retrieval techniques in the world. Evaluate search results at scale. Anton is your evaluation copilot that can judge search results with near‑human precision, available in an on‑demand API.

Voyage AI provides best-in-class embedding models and rerankers designed to supercharge search and retrieval for unstructured data. Its technology powers high-quality Retrieval-Augmented Generation (RAG) by improving how relevant context is retrieved before responses are generated. Voyage AI offers general-purpose, domain-specific, and company-specific models to support a wide range of use cases. The models are optimized for accuracy, low latency, and reduced costs through shorter vector dimensions. With long-context support of up to 32K tokens, Voyage AI enables deeper understanding of complex documents. The platform is modular and integrates easily with any vector database or large language model. Voyage AI is trusted by industry leaders to deliver reliable, factual AI outputs at scale.

Build a natural language interface for your data. NLP is at the core of modern enterprise data processing. We provide developers with the right tools to build production-ready NLP systems quickly and efficiently. Our open-source framework for scalable, API-driven NLP application architectures. We believe in sharing. Our software is open source. We value our community, and we make modern NLP easily accessible, practical, and scalable. Natural language processing (NLP) is a branch of AI that enables machines to process and interpret human language. In general, by implementing NLP, companies can leverage human language to interact with computers and data. Areas of NLP include semantic search, question answering (QA), conversational AI (chatbots), semantic search, text summarization, question generation, text generation, machine translation, text mining, speech recognition, to name a few use cases.

TopK is a serverless, cloud-native, document database built for powering search applications. It features native support for both vector search (vectors are simply another data type) and keyword search (BM25-style) in a single, unified system. With its powerful query expression language, TopK enables you to build reliable search applications (semantic search, RAG, multi-modal, you name it) without juggling multiple databases or services. Our unified retrieval engine will evolve to support document transformation (automatically generate embeddings), query understanding (parse metadata filters from user query), and adaptive ranking (provide more relevant results by sending “relevance feedback” back to TopK) under one unified roof.

Your company knowledge lives across PDFs, spreadsheets, wikis, and ERP exports. Classic RAG retrieves the top-K most similar fragments — fine for summaries, but it fails when answers must be exact and complete. Vedana takes a structure-first approach. You describe your domain as anchors, attributes, and links. Vedana loads your data into a typed knowledge graph, and AI agents explore it step by step: running graph queries, vector search, and assembling answers from real data. The LLM interprets; the data stays the source of truth. What you get: - Exact values: prices, dates, statuses from the graph - Complete results: every matching record, nothing dropped - Multi-hop reasoning: product → category → regulation → document - Traceability: every answer maps to nodes, edges, and chunks - Determinism: same question, same operations Built-in evaluation with golden datasets. Works with any LLM. Open-core, managed cloud, or on-premise. Pilot ships in 4 weeks.
