Perhaps you should try some spelling variations:
closure detection » clone detection, failure detection, seizure detection
feature detection » feature selection, feature extraction
text detection » event detection, object detection, defect detection

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((closure detection) OR (feature detection))) OR (text detection)).
• Adding a wildcard symbol may retrieve word variants: ((((closure detection) or (feature detection))) or (text detection))*.
