Bug Description

While testing OpenRAG accuracy, observed that several questions fail to return responses when no dataset filter is applied. The system returns a fallback message indicating that the information could not be found.
However, when the same query is executed with the appropriate dataset filter, the correct response is generated.

Steps to Reproduce

1. Upload the attached document
2. Navigate to chat and ask questions like:
   What is the total claim amount for California customers?
   Which state has the highest number of customers?
   How many customers are from Washington?
   What is the Customer Lifetime Value of customer BU79786?
   Which customers have more than 1 policy?
