1. Hybrid search

With all Weaviate vectorizers (including CLIP image search), you can also perform an hybrid search to get both precision (only relevant results first) and recall (all relevant results first).

100% classical (sparse) search is relevant but can miss user intents (semantics). On the other hand, 100% vector (dense) search can retrieve too many results that are not relevant, especially on a WooCommerce site.

Weaviate added in release v1.17.0 a new operator “Hybrid”, with an alpha parameter to control how results are calculated from vectors and inverted index.

• (1) Select the “Hybrid” operator
• (2) Set an alpha percentage: 1 for 100% vector search, 0 for 100% inverted index search
