GetSimN

How to retrieve the top N most similar entries from an AI store using the Ahnlich Python SDK.

GetSimN returns an array of tuples (store_key, store_value, similarity_score) of the maximum specified N. This allows you to perform similarity searches against the stored AI embeddings.

• store – Name of the AI store to query.

• search_input – Query input (string or vector).

• closest_n – Maximum number of similar results to return (must be > 0).

• algorithm – Similarity algorithm to use (e.g., Cosine Similarity).

• condition – Optional predicate condition to filter results.

• execution_provider – Optional execution provider.`

The result contains a list of entries with similarity scores.

• closest_n must always be a non-zero integer.

• This request is designed specifically for AI store queries.
