Search for multiple companies matching criteria using natural language and return enriched company data. Use for queries with filters/criteria like 'fintech companies in NY that raised Series B in the last 6 months' or 'AI startups with founders from OpenAI'. DO NOT use for individual company lookups - use typeahead_search with search_type=COMPANY for company name/domain search, or enrich_company for detailed company data by website/domain. This tool returns enriched company information directly, so you don't need to make a separate call to get company details. REQUIRED: You must specify field_groups to control which fields are returned. Select only the smallest field group(s) needed for your question to avoid bloating the response and slowing down the request.

For investors, returns limited fields (entityUrn, type, name, logo) - use get_investors for full enrichment. For multi-company searches with criteria, use search_companies_natural_language instead.
