Type a title, an author, or describe an idea in your own words: Meilisearch matches both the words and the meaning. Open any paper to find related work, then ask questions across the whole corpus, your reading list, or a single paper. Paperscope search page showing a hybrid search for "attention is all you need" with category and year facets ## Key features * **Hybrid search slider**: Move from exact words to meaning in real time by changing `semanticRatio`. The results header shows how many papers were found only by meaning, using `semanticHitCount`. * **Built-in embeddings**: Documents and queries are embedded inside Meilisearch with a HuggingFace model (`BAAI/bge-small-en-v1.5`), with no external embedding service. * **Similar papers**: Each paper lists its nearest neighbours from the `/similar` endpoint, optionally filtered to the same arXiv category. * **Faceted navigation**: Filter by category, topic, author, and year. The year slider uses `facetStats`, and the author box uses facet search. * **Citation-aware ranking**: A custom ranking rule on `citationCount` breaks ties in favor of influential papers, and results can be sorted by citations or date. * **Multi-search**: Papers and matching authors come back in a single request across two indexes. * **Chat with the papers**: The "Ask the papers" page uses the `/chats` route. The LLM runs hybrid searches as a tool and streams its progress and sources. * **Scoped chat with tenant tokens**: Chatting with a reading list or a single paper uses a short-lived tenant token whose search rule restricts retrieval to those papers. ## Links Search and chat with AI research papers Combine keyword and semantic search Learn about the chat route Restrict what each user can search
