What is the best way to implement an internal knowledge base for technical support?

Question

Knowledge base

It is necessary to implement the internal knowledge base of the organization. The main part of the information (which should be stored there) is technical support responses to typical user requests.
The key requirement is a convenient database search (so that you can easily find descriptions of typical situations by various factors that describe the message, for example: technical issue, complex, from the buyer). Ideally - search by tags (along with full-text).
What is the easiest/fastest way to implement this? Perhaps there are ready-made solutions that are close to the requirements, or you can finish it. Thanks in advance for your advice!
