- Neo must begin with only 2-3 terms. Avoid long phrases. (The more terms Neo enters, the fewer results he will get.)
- If Neo's first term doesn’t work, he can try a synonym or a broader term.
Subject terms show how a database organises records:
- These terms can help Neo to locate more items on that topic and related topics.
STEP 1: Phrase searching
"Phrase Searching" means searching for two or more words as an exact phrase. This allows Neo to find documents containing a particular phrase e.g. “air pollution” or “biofuel energy”.
STEP 2: Snowballing
Neo can try Snowballing: assuming he finds at least one relevant journal article he can use as a basis for future searches, for example:
Neo can look at the list of references at the end of the article to see what related work the author has cited.
STEP 3: Nesting
- Nesting (or 'GROUPING') is a keyword search technique that keeps alike concepts together and tells a search engine or database to search those terms placed in parentheses first.
- Using Nesting in a search requires that the items in parentheses be searched first. Generally, the items in parentheses are linked by the Boolean Operator "OR."
- Neo can use Nesting when he is trying to link two or more concepts that may have many synonyms or may be represented by a number of different terms to obtain more comprehensive search results.
- Example: Using (South Africa OR Africa) AND HIV/AIDS will search South Africa or Africa first
