Marqo vector store.
Marqo indexes have their own models associated with them to generate your embeddings. This means that you can selected from a range of different models and also use CLIP models to create multimodal indexes with images and text together.
Marqo also supports more advanced queries with multiple weighted terms, see See https://docs.marqo.ai/latest/#searching-using-weights-in-queries. This class can flexibly take strings or dictionaries for weighted queries in its similarity search methods.
To use, you should have the marqo python package installed, you can do this with
pip install marqo.
