# Add BM25 without rebuilding the shared Qdrant collection
|
|
|
|
The workspace keeps its existing unnamed dense vector and adds only the sparse `bm25`
|
|
vector with IDF through Qdrant's additive vector-schema operation. Only Evidence points
|
|
are repopulated with both default dense and BM25 values. Schema, Memory and solved
|
|
questions retain their current dense points and are verified before and after the
|
|
upgrade.
|
|
|
|
This replaces the planned destructive conversion to a named `dense` vector. If BM25 is
|
|
missing, Evidence preprocessing may add it and verify the resulting schema; session
|
|
runtime remains read-only. An incompatible existing BM25 definition fails without
|
|
mutation. A candidate failure leaves the additive schema in place while Evidence stays
|
|
unavailable, avoiding data loss in the other workflow modules.
