Search screens by natural language scene description using pgvector.
Uses 768-dimensional Gemini embeddings on scene descriptions from FEIN edge AI
to find screens matching a natural language query.
WHEN TO USE:
- Finding screens by audience context ("families eating lunch in a food court")
- Contextual ad placement based on real-time scene understanding
- Discovering inventory matching a specific audience scenario
RETURNS:
Array of matching screens ranked by semantic similarity, each with:
- screen_id, mongo_screen_id, scene_description, contextual_relevance, similarity, created_at
EXAMPLE:
semantic_audience_search({
query: "young professionals in a coffee shop looking at phones",
limit: 10
})
