requires the rerank-cache license feature

The rerank cache stores cross-encoder rerank scores for a query and document pair in a retrieval pipeline, so a repeated pair does not have to be scored again. RERANK.FLUSH empties a namespace. The namespace keeps its settings, so you can store new entries straight away. To remove the namespace itself, use RERANK.DROP.

Return value

Section titled “Return value”
Case RESP2 RESP3
Always Integer: the number of entries removed (0 for an unknown namespace) Same

Errors:

  • ERR wrong number of arguments for 'rerank.flush' command if the argument count is wrong.
