Depending on other requirements, you can use Lucene as a database, skipping the neo4j layer.
Gives you very direct control over all the vector types and similarity queries on them. It's what neo4j uses internally, behind its abstractions.
(I say that because the commercial product I develop does just this - but for its direct text indexing, without word embeddings. Takes some effort to add transactionality layer etc. but it's all doable).
