Can this product support multilingual search? My interest is for a prospective project in rehabilitation research.
Pinecone supports vector search. Our customers use a language model to transform sentences or text into vectors that they store and search with Pinecone. Hugging Face is one popular repository of such models. A few of the models there are multi-lingual. See this link: Multi-lingual models
Once you select a model and transform your text into vectors, you can use Pinecone to quickly and reliably search millions to billions of such vectors in your applications. You can read about multilingual models here too!
