Keyword aliases for the shared fusion parameters.

Each fusion SQL surface picks one of the *_KEYWORDS constants below. New fusion variants add their own constant rather than editing the extractor.

Fields

vector_top_k: &'static str

expansion_depth: &'static str

edge_label: &'static str

final_top_k: &'static str

rrf_k: &'static str

vector_field: &'static str

direction: &'static str

max_visited: &'static str

query_anchor: &'static str

Keyword that precedes ARRAY[...] in raw SQL (e.g. QUERY or ARRAY itself when there is no leading keyword).

bm25_query: &'static str

Keyword that precedes the BM25 query string for three-source fusion. Empty string disables BM25 parsing for surfaces that do not support it.

bm25_field: &'static str

Keyword that precedes the BM25 field name in three-source fusion.
