Required terms in different fields produce a same-field hit · case 05
Required terms in different fields produce a same-field hit.
Case contract
Return whether any single field contains all query terms. Empty query matches any existing field; no fields never matches.
Why this case matters
An offline deterministic retrieval model isolates this search contract from tokenization, storage, and network behavior.
One recorded failure
