Filter by boolean scores

Tobias Wochinger

Filter Langfuse tables by true or false score values.

You can now filter Langfuse tables by boolean scores in the sidebar or Filter Search Bar.

Boolean score filters are available across traces, observations, sessions, datasets, experiments, evaluations, and scores. In the search bar, use the same score syntax as other score types:

scores.is_hallucination:true
scores.is_hallucination:false

Autocomplete detects boolean scores and suggests true or false.
