🧮 Expert search (AND / OR / NOT)

Tick "🧮 Expert" — the search box then understands Boolean combinations. This allows questions that simple searches cannot answer:

Write operators in capitals: lower-case they are treated as search words (verified: "Marburg or Kirche" = 10 hits, because the word "or" must occur). Correct: OR.

Why this mode exists: The archive engine itself silently returns wrong results for mixed combinations (e.g. A NOT B C or parentheses with OR) — terms disappear or roles are swapped without warning. The portal checks every input and automatically splits it into safe partial searches whose results are merged:

Historical place search: For many places (e.g. Neustadt, Kirchhain, Homberg), a box appears automatically with the administrative chain (office → district → rural district) — old holdings are often filed under the historical district, not under the place name. Chain links are clickable: clicking narrows the search to that administrative unit; an extra link resets the search to the original query. The box appears in the Arcinsys search and in the all-database search — also for people (e.g. “Zwetsch”) and institutions (e.g. “Philipps-Universität”). The chain comes from curated data or — for places not yet curated — automatically from the Historical Place Lexicon (LAGIS). If a chain is wrong or incomplete, it can be reported directly via the “Chain wrong? Report a correction” link in the box — the report goes to the curation queue and feeds back into the curated data.
