Example structured index with multiple fields and features

The following example shows how to create a structured index with multiple fields and features.

import marqo

settings = {
    "type": "structured",
    "model": "open_clip/ViT-L-14/laion2b_s32b_b82k",
    "allFields": [
        {"name": "name", "type": "text", "features": ["lexical_search"]},
        {"name": "description", "type": "text"},
        {"name": "is_nsfw", "type": "bool", "features": ["filter"]},
        {"name": "price", "type": "float", "features": ["filter"]},
        {"name": "tags", "type": "array<text>", "features": ["filter"]},
        {"name": "image_url", "type": "image_pointer"},
        {"name": "seller_score", "type": "float", "features": ["score_modifier"]},
        {
            "name": "multimodal_field",
            "type": "multimodal_combination",
            "dependentFields": {"image_url": 0.9, "name": 0.1},
        },
    ],
    "tensorFields": ["multimodal_field"],
}

mq = marqo.Client(url="http://localhost:8882")

mq.create_index("my-complex-index", settings_dict=settings)

This example represents a more realistic system which allows for more complex behaviours such as filtering, score modification and multimodal search.

Example Add Documents Usage

documents = [
    {
        "_id": "1",
        "name": "Marqo T-Shirt",
        "description": "A high-quality t-shirt with the Marqo logo.",
        "is_nsfw": False,
        "price": 19.99,
        "tags": ["clothing", "t-shirt", "merchandise"],
        "image_url": "https://my-image-store.com/marqo-t-shirt.jpg",
        "seller_score": 0.8,
    },
    {
        "_id": "2",
        "name": "Marqo Hoodie",
        "description": "A high-quality hoodie with the Marqo logo.",
        "is_nsfw": False,
        "price": 39.99,
        "tags": ["clothing", "hoodie", "merchandise"],
        "image_url": "https://my-image-store.com/marqo-hoodie.jpg",
        "seller_score": 0.9,
    },
]

mq.index("my-complex-index").add_documents(documents)

Example Search Usage

Basic Search:

results = mq.index("my-complex-index").search(q="Marqo T-Shirt")

Search with Filtering:

results = mq.index("my-complex-index").search(
    q="Marqo T-Shirt", filter_string="tags:hoodie"
)

Search with Score Modification:

mq.index("my-complex-index").search(
    q="Marqo T-Shirt",
    score_modifiers={"add_to_score": [{"field_name": "seller_score", "weight": 0.01}]},
)
