[Ikuni17]

Code search can exclude one exact host, organization, and repository before ranking and the result limit. Optional exclusion parameters default to empty strings, so existing callers keep their behavior. Libra uses this to find external integrations when the reviewed repository would otherwise fill the result window.

Part of elastic/libra#126. Supports elastic/libra#585.

Validation

• Full Python suite: 910 tests passed.
• Focused setup/tool tests: 57 passed.
• Complete shipped query against local Elasticsearch 9.5.3: exclusion returns EUI at limit 1 when Kibana otherwise fills the result window. Snapshot/delta, exact identity, omitted/partial defaults, wildcard literals, and case normalization passed.

Rollout

Install the updated definition with the existing sourcerer setup tools command before deploying the Libra consumer. No indexing changes are required.
