Minimum score for retrieved passage

[hermans0101g]

Is it possible to restrict passages that get passed to the reader by threshold?

Thanks

Hello @hermans0101g currently, Haystack does not support filtering the output of retriever nodes based on the relevance scores of the passages. However, the output of reader nodes can be filtered based on a threshold:

haystack/haystack/nodes/reader/farm.py

Line 122 in dcb132b

:param confidence_threshold: Filters out predictions below confidence_threshold. Value should be between 0 and 1. Disabled by default.

I'd suggest that you have a look at how the implementation works for the reader. Maybe you can use it as a blueprint for the retriever?
