Load an existing database?

[coronatime150]

Tried setting a different dir for chroma but seems to go back to updating the default /db location.

'vectordb': {
'provider': 'chroma',
'config': {
'collection_name': 'test_app2',
'dir': 'db1',
'allow_reset': True
},
},

If I start new file using same config for 'vectordb' and app name, it does not see previous embedded vectors.
