Returns up to `limit` matching members and up to `limit` matching tickers, each ordered by trade count. Use it to turn a common or partial name into the exact stored name that get_member_trades and get_member_profile require. A member who filed under several spellings appears once, under one of them, with trade_count summed across all of them, so get_member_trades on that name can return fewer trades. It matches substrings only and does not correct misspellings. - after: Case-insensitive substring search over member names, ticker symbols, and company names. Returns up to `limit` matching members and up to `limit` matching tickers, each ordered by trade count. Use it to turn a common or partial name into the exact stored name that get_member_trades and get_member_profile require.
