The filtered result set is the union of the genuine keyword matches and that query-independent floor, not a subset of the same search run unfiltered. A query that matches nothing still comes back as…",

      "Excerpt": "### Use case\n\nWhen `met_search_collections` returns `no_results` because `isPublicDomain: true` zeroed out an otherwise-matching query, the generic recovery hint (\"broaden the query, remove filters…\") doesn't name the filter responsible, so callers retry with different keywords against the same filter set and fail identically.\n\nRelated: #12\n\n### Proposed behavior\n\nWhen the `no_results` throw fires and `input.isPublicDomain === true`, override the recovery hint at the `ctx.fail('no_results', …)`…",

Real titles already contain complete Markdown sequences — object `288322`'s title (confirmed live) is `[Group of 122 Stereograph Views of Egypt, the Holy Lands, and the Middle East, Including Palestine and Jerusalem]`, and this is not a one-off: the Met's cataloging convention wraps a cataloger-supplied (non-artist) title in square brackets for anonymous photograph…",

A catalog researcher can find a work by city, state, excavation, or locus and then lose the field that explained the match.
