Temporal Search

Overview

Time-decay relevance scoring for time-aware retrieval.

Temporal Search Query

Apply time decay to relevance scores:

-- Temporal search with decay
SELECT * FROM temporal_search(
    'documents',
    embed_text('query'),
    'timestamp_column',
    INTERVAL '30 days',  -- decay period
    0.5,                 -- decay factor
    10                   -- top K
);

Time-Weighted Ranking

Boost recent documents:

-- Time-weighted hybrid search
SELECT id, content,
       temporal_hybrid_score(
           embed_text('query'),
           embedding,
           created_at,
           INTERVAL '7 days',
           0.3  -- time weight
       ) AS score
FROM documents
ORDER BY score DESC
LIMIT 10;
