It supports both full-text and vector searches. ## Choose when ### Choose meilisearch if… - meilisearch is primarily Rust; gpl is Python. - License: meilisearch is Other, gpl is Apache-2.0. - Tags unique to meilisearch: ai, api, app-search, database. - meilisearch ships Docker support for self-hosted deployment. - - You require fast integration capabilities for your web or mobile application, as Meilisearch offers flexible deployment options. ### Choose gpl if… - gpl is primarily Python; meilisearch is Rust. - License: gpl is Apache-2.0, meilisearch is Other. - Tags unique to gpl: bert, domain-adaptation, information-retrieval, nlp. - Also covers Model Training. ## When NOT to use meilisearch - - When you specifically need language support for a large number of languages beyond what Meilisearch currently offers, as some specialized multilingual search engines might handle more languages nimb - - If your application does not require real-time search-as-you-type or typo tolerance features which can add overhead and may slow down performance in less demanding scenarios. ## When NOT to use gpl - Last GitHub push was 1102 days ago (dormant maintenance, Jul 6, 2023). Validate activity before betting a new project on gpl. - Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. - Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate. ## Common questions ### What is the difference between meilisearch and gpl? meilisearch: A lightning-fast search engine API bringing AI-powered hybrid search to your sites and applications.. gpl: Powerful unsupervised domain adaptation method for dense retrieval.
