description: "Search clinical trials by study acronym.

Uses the Acronym field (protocolSection.identificationModule.acronym) to find

with the provided acronyms to narrow results, then results are filtered locally
to ensure the acronym field matches the requested value(s).

Input:
  - `acronyms`: One or more acronyms to search for (e.g., ['TETON']).
  - `max_studies`: Maximum number of studies to request from the API.
  - `exact_match`: When true (default), matches acronyms exactly (case-insensitive).
                   When false, matches if any provided acronym is contained within
                   the study acronym (case-insensitive partial match).
  - `fields`: A list of specific fields to return in the results. If not provided, returns
              ACRONYM_SEARCH_DEFAULTS (8 fields optimized for acronym discovery: NCTId,
