Step-by-step explanation:
The table used to store all the searches performed against knowledge base articles is kb_search_log. In database systems that support knowledge base platforms, various tables are usually designed to keep track of different types of data. When a user performs a search within the knowledge base, the search terms, the number of results returned, and possibly the user's information may be logged into this specific table.
This ensures that there is a record of what information is being sought, which can be useful for analytics, understanding user needs, improving search relevance, and ensuring the knowledge base contents are meeting the needs of the users. The kb_search_log table, as implied by its name, is meant to log all the search-related activities on the knowledge base articles.
