In most cases a phrase is searched as it is entered. Searching for names as subjects. A limited number of personal, test, and drug names are found in the Thesaurus controlled vocabulary. Other names may be searched free-text in the Title, Key Phrase, Abstract, and Table of Contents. These are entered in first initial, last name format.
Brand names retrieve few, if any, records.
Add terms from the population fields to your search scheme. It is surprising sometimes how much a search can be improved by merely limiting to a human population. For instance, if you want to know about the efficacy of a drug for humans, you may not want to see the animal research. Likewise, if your interest is women in sports , you can do the search on athletes and limit the results to a female population. Since population categories are assigned each time they occur, many articles will be identified by both male and female population tags.
