Hi,

I want to implement pseudo-relevance feedback, together with a bm25 ranking function, for a full-text search application. Is there any reference that I can look up for implementing this? I have just one field in my index.

Thank you.

Welcome to our community! 😃

Are you using Enterprise Search or Elasticsearch?
