# SurfacePatternsFile

The path to the Passage Extractor surface patterns file. This parameter applies only when Type is set to `PassageExtractor`.

Passage Extractor uses surface patterns to find the possible forms that an answer to a particular question might take. It attempts to match candidate answers against the surface patterns to find the best match.

If you move or rename the surface patterns JSON file, set `SurfacePatternsFile` to the new name and location.
