Default seed-scoped graph expansion adds filtered one-hop linked candidates after first fusion
Reranking pushes the most relevant results to the top
Date filters (--since, --until) for time-sensitive work
Tag, category, author, and language filters stay active when graph retrieval is enabled
Intent steering to bias results toward a topic
Exclusion filters to remove noise
Structured query modes for power users (term, intent, hyde)
Trusted local project affinity adds one bounded, explainable workspace signal
contentTypes searchBoost adds a bounded query-agnostic prior without bypassing filters
Every retrieval stage is configurable
