    """
    OpenAI-like chat completion API that simulates the behavior of OpenAI's completions endpoint.
    
    This function allows users to interact with a model and receive responses based on a series of historical messages.
    If `stream` is set to True (by default), the response will be streamed in chunks, mimicking the OpenAI-style API.
    Set `stream` to False explicitly, the response will be returned in a single complete answer.
    Example usage:

    curl -X POST https://ragflow_address.com/api/v1/chats_openai/<chat_id>/chat/completions \
        -H "Content-Type: application/json" \
        -H "Authorization: Bearer $RAGFLOW_API_KEY" \
        -d '{
            "model": "model",
            "messages": [{"role": "user", "content": "Say this is a test!"}],
            "stream": true
        }'

    from openai import OpenAI

Objective: To generate search terms related to the user's search keywords, helping users find more valuable information.
Instructions:
 - Based on the keywords provided by the user, generate 5-10 related search terms.
 - Each search term should be directly or indirectly related to the keyword, guiding the user to find more valuable information.
 - Use common, general terms as much as possible, avoiding obscure words or technical jargon.
 - Keep the term length between 2-4 words, concise and clear.
 - DO NOT translate, use the language of the original keywords.

### Example:
Keywords: Chinese football
Related search terms:
1. Current status of Chinese football
2. Reform of Chinese football
3. Youth training of Chinese football
4. Chinese football in the Asian Cup
5. Chinese football in the World Cup

Reason:
 - When searching, users often only use one or two keywords, making it difficult to fully express their information needs.
 - Generating related search terms can help users dig deeper into relevant information and improve search efficiency. 
 - At the same time, related terms can also help search engines better understand user needs and return more accurate search results.
