Scan keys in the Redis database using the SCAN command (non-blocking, production-safe). ⚠️ IMPORTANT: This returns PARTIAL results from one iteration. Use scan_all_keys() to get ALL matching keys, or call this function multiple times with the returned cursor until cursor becomes 0. The SCAN command iterates through the keyspace in small chunks, making it safe to use on large databases without blocking other operations. Args: pattern: Pattern to match keys against (default is "*" for all keys). Common patterns: "user:*", "cache:*", "*:123", etc. count: Hint for the number of keys to return per iteration (default 100). Redis may return more or fewer keys than this hint. cursor: The cursor position to start scanning from (0 to start from beginning). To continue scanning, use the cursor value returned from previous call. Returns: A dictionary containing: - 'cursor': Next cursor position (0 means scan is complete) - 'keys': List of keys found in this iteration (PARTIAL RESULTS) - 'total_scanned': Number of keys returned in this batch - 'scan_complete': Boolean indicating if scan is finished Or an error message if something goes wrong. Example usage: First call: scan_keys("user:*") -> returns cursor=1234, keys=[...], scan_complete=False Next call: scan_keys("user:*", cursor=1234) -> continues from where it left off Final call: returns cursor=0, scan_complete=True when done

Scan and return ALL keys matching a pattern using multiple SCAN iterations. This function automatically handles the SCAN cursor iteration to collect all matching keys. It's safer than KEYS * for large databases but will still collect all results in memory. ⚠️ WARNING: With very large datasets (millions of keys), this may consume significant memory. For large-scale operations, consider using scan_keys() with manual iteration instead. Args: pattern: Pattern to match keys against (default is "*" for all keys). batch_size: Number of keys to scan per iteration (default 100). Returns: A list of all keys matching the pattern or an error message.

Perform a hybrid search combining a Redis filter expression with KNN vector similarity.

Defaults to '*' (no filter). index_name: Name of the Redis index (default: 'vector_index'). vector_field: Name of the indexed vector field (default: 'vector'). k: Number of nearest neighbors to return. return_fields: Additional fields to include in results (optional). Returns: A list of matched documents with their similarity score, or an error message.
