Do you need to file an issue?

• I have searched the existing issues and this bug is not already filed.
• My model is hosted on OpenAI or Azure. If not, please look at the "model providers" issue and don't file a new one here.
• I believe this is a legitimate bug, not just a question. If this is a question, please use the Discussions area.

Describe the issue

In the file graphrag/prompts/query/drift_search_system_prompt.py, there are the following three prompts:
DRIFT_LOCAL_SYSTEM_PROMPT = """"""
DRIFT_REDUCE_PROMPT = """"""
DRIFT_PRIMER_PROMPT = """"""
I found that DRIFT_REDUCE_PROMPT is not used in the code. What is the relationship between DRIFT_PRIMER_PROMPT and DRIFT_LOCAL_SYSTEM_PROMPT? How should I modify them so that the final output meets my requirements?
Because I found that when I modify the content in DRIFT_LOCAL_SYSTEM_PROMPT, the final output format does not output as expected.
