min_host_rank
floatSets a floor on the authority of the publishing host.
Host rank is computed from the link graph. Raising the floor is the bluntest and most effective filter against low-quality sources, and it costs nothing at query time because the value is baked into the index.
Example
curl -H "x-api-key: $UNLOB_API_KEY" \
"https://api.unlob.com/search?q=vaccine+efficacy&min_host_rank=0.6"Common questions
