Problem Description

At first when search was using empty results for my own data I thought I was doing something wrong, so then I used the example data from the quickstart guide: https://help.getzep.com/graphiti/graphiti/quick-start

But I'm still getting empty output for the example data used in the quickstart guide so maybe there is something else up here.

Note that I do see my credits being billed each ingest run in my OpenAI billing console.

Maybe I'm missing something? If you could take a look and guide me that will be highly appreciated.

Please do let me know if I can provide any additional data.

@surajrav Thanks for raising the issue, I was able to reproduce it locally too. It happens when no group_id is passed when adding episodes. We will push a patch for it soon.

As a quick fix, you can pass a group_id argument when adding the episodes and also specify it when searching graphiti. Group id is a developer provided string to describe an isolated region in the graph, we will be highlight its usage in the docs soon!

for i, episode in enumerate(episodes):
        await graphiti.add_episode(
            group_id='group1',
            name=f'Freakonomics Radio {i}',
            episode_body=episode,
            source=EpisodeType.text,
            source_description='podcast',
            reference_time=datetime.now(),
        )
...

results = await graphiti.search(query, group_ids=['group1'])
...
