// SearchQuery is the query for GET /search. Q is required; all else optional.
// DateFrom/DateTo are epoch-ms. Q holds at most 1000 characters and 32 words (the server answers 400
// above either). Limit defaults to 50 and is capped at the server's SEARCH_LIMIT_MAX (100 by default);
// Offset is at most 100000 (400 above). Match is "word" (the server default: whole words) or "contains"
// (any part of a word, ignoring case and accents). "contains" needs SEARCH_CONTAINS_ENABLED=true and a
// finished index build on the server (501 otherwise) and at least one term of 3+ characters with at most
// 64 characters across its terms (400 otherwise); it ranks the 1000 most recently stored matches, so
// Total is at most 1000.
