Searches a company's candidates across all positions, accepting the same parameters as the GET form but in a JSON body.

The endpoint has two modes:

• email_address — exact match on the normalized (lowercased, trimmed) email address, company-wide. This mode takes precedence when both parameters are supplied and returns a bare array of reduced candidate entries (the { total, data } envelope is not used), identical to the GET email lookup.
• filter_text — free-text search across the company's candidates via OpenSearch, returning the paginated { total, data } envelope described below. Each entry in data is a full candidate list summary (id, name, contact info, stage, source, score, tags, etc.) with the associated position attached.

At least one of email_address or filter_text is required; a request with neither returns 400. sort must be created or updated (defaults to updated); any other value returns 400. Pagination applies to the free-text mode only: page_size defaults to 50 and is capped at 50, and page defaults to 0 and is clamped to a maximum of 19 (20 pages). archived defaults to true so the search spans the company's full candidate history; set it to false to exclude archived candidates.
