A. Describe ways to find keywords to use when searching for information on a topic.
In a search of all EBSCO databases, perform the searches below. The write down the number of records in the search results.
HINT: Go to "Advanced Search". Enter the search terms into boxes on separate lines. Pick the combining word (and / or / not) from the drop down list between the two lines.
A. Which of the searches had the highest number of results? Why?
B. Which of the searches had the lowest number of results? Why?
C. Enter the search adolescents NOT depression (use the hint given above). Was the number of records more, less, or the same as the search results for: adolescents? Why?
A. The largest number of results was for: adolescents OR depression, because if a record has either of the words in it, it was retrieved. When terms are combined with OR, then a record can have one or both of the terms in it.
B. The search with the least results was: adolescents AND depression, because only records with BOTH terms would be retrieved.
C. The search: adolescents NOT depression yielded less results than the search for: adolescents. Because all records from the search for adolescents that also had the word depression were excluded.
In the EBSCO and/or ProQuest database(s), practice strategies listed below.
A. Truncation - Compare the results of the searches below. Which has more results, and why?
B. Phrase searching - Compare the results of the searches below. Which of has more results, and why?
C. Title field searching - Compare the results of the searches listed below. Which has more results, and why?
D. Lists of "Subjects" or "Identifier/Keyword" - In article records, use the "subjects" (EBSCO) or the "idendifier/keyord" (ProQuest) lists for search term ideas.
C. Title field searching - Searching only the title field of the records for publications will yield fewer results than when all fields (anywhere) in the records is searched. Searching only the title field may help to shorten the list of results to records that are more likely to focus on the topic of interest, because keywords in a title suggests the publication emphasizes the topic represented by the keyword search terms.
Example 1: global warming (no field selected; default search is all fields)
Example 2: global warming in the title of publications
