"""
Retrieves the top-k most relevant chunks for a given query using the specified similarity metric.
This method encodes the input query into an embedding and computes similarity scores between
the query embedding and the precomputed vector index. The similarity metric can be either
cosine similarity or Euclidean distance. The top-k chunks with the highest similarity scores
are returned as a list of dictionaries, each containing a chunk and its corresponding score.
