Focused Questions and telegram style search formulations – suitable for NHS Evidence Telegram style searching: Take your clinical or healthcare planning question and select those words you would send as a telegram to a friend in New Zealand to make them aware of your question. To concentrate your mind, imagine each word cost £50 – use only the minimum of search words!

NHS Evidence: Some Gripes � Most recent studies ‘hidden’ if relevance ranking is used (default) � Authors not always visible in result list � Search sometimes too sensitive: irrelevant hits � NHS Evidence is not a true Point-of-Use resource � Dynamed will be missed, CKS to be developed!!
