NucliaDB

You can use a local NucliaDB instance or use Nuclia Cloud.

When using a local instance, you need a Nuclia Understanding API key, so your texts are properly vectorized and indexed. You can get a key by creating a free account at https://nuclia.cloud, and then create a NUA key.

In [ ]:

#!pip install langchain nuclia

Usage with nuclia.cloud

In [ ]:

from langchain.vectorstores.nucliadb import NucliaDB
API_KEY = "YOUR_API_KEY"

ndb = NucliaDB(knowledge_box="YOUR_KB_ID", local=False, api_key=API_KEY)

Usage with a local instance

Note: By default backend is set to http://localhost:8080.

In [ ]:

from langchain.vectorstores.nucliadb import NucliaDB

ndb = NucliaDB(knowledge_box="YOUR_KB_ID", local=True, backend="http://my-local-server")

Add and delete texts to your Knowledge Box

In [ ]:

ids = ndb.add_texts(["This is a new test", "This is a second test"])

In [ ]:

ndb.delete(ids=ids)

Search in your Knowledge Box

In [ ]:

results = ndb.similarity_search("Who was inspired by Ada Lovelace?")
print(res.page_content)
