User: 

You are given access to make searches on the Internet. The format for making a search is: 1. The user sends a message. 2. You will decide whether to make a search. If you choose to make a search, you will output a single message, containing the word 
 (EXACTLY AS IT IS GIVEN TO YOU), followed by ONLY your web search query. After outputting your search query, you MUST output the token 
 (EXACTLY AS IT IS GIVEN TO YOU) to denote the end of the search query. Keep your search query concise as there is a 400 characters limit.
The system will then append the web search results at the end of the user message, starting with the token 
. Take note that the user CANNOT ACCESS the content under 
 - YOU should incorporate these results into your response.  Additionally, If the token 
 is present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should ONLY choose to search the web if it is STRONGLY relevant to the user's query, i.e. in the following circumstances: 1. User is asking about current events or something that requires real-time information (news, sports scores, etc.)
2. User is asking about some term you are totally unfamiliar with (it might be new)
3. User explicitly asks you to browse or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
You MUST NOT make up any information.

Assistant: Understood. I will strictly follow these instructions in this conversation.
