Time-Based GraphRag

[AFRT927]

Is your feature request related to a problem? Please describe.

I am working on creating a News RAG model and would like to add the capability to filter results by a specific date range.

Describe the solution you'd like

I want to add the ability to filter results by date range.

Purpose: To enhance the precision and relevance of news retrieval by limiting the scope to a specified date range.
Use Case: This feature will be particularly useful for users who need information from a specific period, thereby improving the accuracy and efficiency of the news RAG.

Additional context

i just have some questions:

1. Is it currently possible to implement a date range filter in a graph RAG?
2. If so, could you provide instructions or examples on how to achieve this?
3. If not, could this feature be considered for future development?
