Module tokenql 

Token-only IKL — the single retrieval language, an s-expression over the postings store. Ported 1:1 from the TS tokenql.ts evaluator: <atom> a tag or glob pattern → UNION of matching tokens’ postings, ∩ scope (and A B …) → ∩ (also the default for a bare list) (or A B …) → ∪ (not A) → scope − A (closed-world inversion) (The num typed range predicate is stubbed here — it belongs to the columnar numeric layer, which is a separate benchmark; set-algebra is what we’re measuring.)

Enums

Node

QueryError

Why a query could not be evaluated. Separate from “matched nothing”, which is an answer.

Traits

TokenStore

Functions

evaluate

Evaluate a query, returning empty on refusal. Kept for callers that cannot act on an error.

parse

Parse an s-expression. Atoms stay strings; "quoted atoms" keep spaces.

try_evaluate

Evaluate a query, surfacing refusals.
