create and store vector index

[IamExperimenting]

Hi ,

since, it is taking longer time create vector index for n number of files, is it possible to create and store the vector index? and re-use it whenever we want. Rather not run from the beginning and create a new vectorstoreindex again.

Any help would be greatful.

@IamExperimenting just asking for clarification are you asking about loading the vectorstore from a stored place then you can do this with chroma vector so you just feed data to it and save it locally to use it whenever you need

docsearch = Chroma(collection_name='docs',persist_directory='db', embedding_function=embedding)
# load data to the vector store
#--------------------------------
#--------------------------------
docsearch.persist()
docsearch = None

To load it and use it just simply do this that is it

docsearch = Chroma(collection_name='docs',persist_directory='db', embedding_function=embedding)

you can now use it in your program anywhere required
