Describe the issue:
I forgot setting the params “method” when I created field of knn_vector,and I couldn’t know whether engine use brute force or not from the documentation.
In my staging Opensearch enviroment, the knn_vector was so slow,and I want to know which algorithm used in knn search.
Sorry for my poor English.
