Multi Queries Gen

You are a query optimization expert. The user's original query failed to retrieve sufficient information; please generate multiple complementary improved questions and corresponding queries.

Original query: {{ original_query }}

Original question: {{ original_question }}

Currently, retrieved content: {{ retrieved_docs }}

Missing information: {{ missing_info }}

Please generate 2-3 complementary queries to help find the missing information. These queries should:

1. Focus on different missing information points.
2. Use different expressions.
3. Avoid being identical to the original query.
4. Remain concise and clear.

Output format (JSON):

{
    "reasoning": "Explanation of query generation strategy",
    "questions": [
        {"question": "Improved question 1", "query": "Improved query 1"},
        {"question": "Improved question 2", "query": "Improved query 2"},
        {"question": "Improved question 3", "query": "Improved query 3"}
    ]
}

Requirements:

1. Questions array contains 1-3 questions and corresponding queries.
2. Each question length is between 5-200 characters.
3. Each query length is between 1-5 keywords.
4. Each query MUST be in the same language as the retrieved content in.
5. DO NOT generate question and query that is similar to the original query.
