am trying to build a similarity search in python, cannot debug the function:
def perform_similarity_search(query_text, index, embeddings, top_k=5):
“”“Perform similarity search in the FAISS index for a given query text.”“”
Use the embeddings object to embed the query_text into a vector.
Ensure the text is passed as a list and the result is accessed correctly.
query_vector = embeddings.encode([query_text])
Reshape the query_vector for compatibility with FAISS search method if necessary.
FAISS expects the query vector to be a 2D array.
if len(query_vector.shape) == 1:
query_vector = query_vector.reshape(1, -1)
# Search the index using the reshaped query_vector.
distances, indices = index.search(query_vector, top_k) # Search the index for the top_k closest vectors
return distances, indices
def run_indexing_pipeline():
documents = fetch_documents(documents_dir)
text_chunks = divide_documents_into_text_chunks(documents)
embeddings_model = prepare_embeddings()
faiss_index = build_and_store_faiss_index(text_chunks, embeddings_model, faiss_db_path)
# Example query for testing purposes
query = "Enter some example text here"
distances, indices = perform_similarity_search(query, faiss_index, embeddings_model)
print("Distances:", distances)
print("Indices:", indices)

This is error being shown, pls let me know how I can correct it
