A white card search refers to a query or search operation that has no predefined limitations or filters, offering unrestricted and open-ended results. This term is not a standard in common search methodologies but is sometimes used metaphorically to describe:
1. Unfiltered Searches: Queries where no constraints (like keywords, time ranges, or content type) are applied, akin to a “clean slate” or unrestricted exploration.
2. Custom Search Criteria: The user is free to define their own filters or criteria without any pre-applied restrictions.
