I'm doing a systematic review, and I'm checking to see if some papers that I know are important will be recovered by my search string. One of these papers is "Tutorial for Using Control Systems Engineering to Optimize Adaptive Mobile Health Interventions". When I search "Adaptive Mobile Health Interventions"[Title/Abstract], without the tag, this paper shows up, however, with it, it doesn't. Just wondering why this is?

Any help would really be appreciated.

  • You should ask the MEDLINE helpdesk. We don't know what their search algorithm does.

    Shows up just fine on Web of Science when searching on all-fields or just on title. An interesting bug, but probably not answerable here.
