Describe the issue

Suppose I have documents from 10 different companies, and after importing them into GraphRAG, there will be a situation where the data gets mixed up. For example, when querying the founder or related information of Company A, the results show the information of Company B. For this situation, do you have any suggestions for handling it?

Hi @jarrett-au Yup, you bring a great point, and we have faced this situation. Some tips for things you can try:

Add contextual info to you input files as a preprocess step. For example, put the file name or any relevant information (in our case, for example, we included the Podcast Episode number and guest in the file itself).
Create or modify your own chunks for the input file. You can take the create_base_text_units.parquet file an update it by adding some information to each row as you find fitting.
