Rerank candidate documents against a query

post/v1/graph/rerank

Request body

top_kinteger nullable

Return at most this many results. Defaults to len(documents).

domain_idstring nullable

Domain shortname or full schema id controlling which frequency bands and extraction rules are used. Built-in shortnames: "general" (default), "code", "cosqa", "codetrans", "codetransocean", "codetransocean_hybrid", "text2sql", "scifact", "nfcorpus", "fiqa", "legal", "medical", "ecommerce", "coffee_shops". You can also pass a full schema id (e.g. "code_search:cosqa:2.0.0") or a custom domain_id registered via POST /v1/graph/domains.

method'fast' | 'enhanced'

Public: enhanced (CAESAR-8) or max (CE+entailment). Accepts deprecated 'fast'/'enhanced' aliases.

signal_embedder'sbert' | 'qwen'

Embedder for per-band signal vectors when extracting query/docs. 'sbert' (384d, default) is ~10x cheaper to store than 'qwen' (2560d). Must match the embedder used for any BYO signal_embeddings.

signal_filtersobject nullable

Hard cutoffs on per-frequency signals, e.g. {'domain_match': 0.6}. Docs below are dropped.

signal_multipliersobject nullable

Per-frequency scoring weight multipliers. Keys may be field names (e.g. 'claim_stance', 'causal_verb') or Hz-strings (e.g. '19.0'). Values: 'auto' (default) or 1.0 = unchanged, 2.0 = 2x boost, 0.0 = disable that band. Fields not specified default to 'auto'. Stacks on top of the schema-level FrequencyField.weight multipliers; request-level overrides win on conflict.

return_signal_scoresboolean

If true, each result carries signal_scores (method-level scores like base_sim, caesar8_score) and signal_scores_by_band (per-frequency band alignments such as key_apis, language).

return_documentsboolean

If true, echo back each input document in the result.

return_debugboolean

If true, include CAESAR meta-signals + timing in meta.debug.

Response

Successful Response

idstring required

Request id for log correlation.
