Optional. A list of searches to run in ONE actor run instead of one run per person. Each entry takes the same fields as a single search (searchMode, firstName, lastName, city, state, phone, address, profileUrl) — searchMode is NOT inherited from the top level (so a batch can mix name/phone/address/profileUrl lookups), every other top-level field is used as a per-entry default. maxItems caps the WHOLE run's total records; set maxItemsPerSearch too if you want a guaranteed share per entry (e.g. 30 entries, maxItems 30, maxItemsPerSearch 1 for one record per person). NOTE: this target is cleared via Bright Data's Web Unlocker on every single fetch, unlike our browser-based actors — there is no shared browser session to reuse, so batching does NOT lower the per-record cost or speed up the clearance step here. It DOES save you from launching N separate runs and guarantees each entry its own share of the budget. Leave empty to run a single search.
