/**
 * Search strategy for a natural-language search request. `auto` keeps the server pipeline (exact-name shortcut first, planner otherwise); `exact` matches entity or person names exactly with no planner and no embedding; `keyword` runs full-text search; `semantic` runs vector similarity; `natural` always runs the language-model planner; `hybrid` fuses keyword and semantic rankings by reciprocal rank. Entity and person natural-search support every mode but `hybrid`; news and federated search accept only `auto` and `keyword`; content search accepts `auto` (topic, type, relation, and year words become filters and any other words rank by full text), `keyword` (the full text of articles, posts, and fetched pages), `semantic` (one entity's or person's library pages by vector similarity of their fetched bodies), and `hybrid` (that owner's keyword and semantic rankings fused; each ranking is cut at the largest page size, so a hybrid search returns at most twice that many items, and it orders by fused rank only, ignoring `sort`).
