Phrase Searching Tips
Most databases allow you to specify that adjacent words be searched as phrases.
-
Using parentheses or quotes around search words is a common way to do phrase searching, but not all databases or search engines use them.
-
Example: "genetic engineering"
-
Hint: It is often very easy to do phrase searching from the Advanced or Guided search in a database.
What to Look For
-
Different databases interpret searches differently. A common variation is how databases recognize phrases.
-
Some assume that words typed next to each other should be searched as phrases.
-
Others automatically put a Boolean AND between your search terms, requiring that all the words be present, but not necessarily adjacent to each other.
-
These searches can retrieve very different results.
Proximity Operators
-
Many databases allow you to specify that the words you are searching are within a certain proximity of each other.
-
Proximity operators are more specific than Boolean operators and make your search more precise.
Proximity Operator Examples
Proximity operators also vary by database, but some common ones include:
w# = with
-
With specifies that words appear in the order you type them in.
-
Substitute the # with a number of words that may appear in between. If no number is given, then it specifies an exact phrase.
-
Examples:
genetic w engineering (searches the phrase genetic engineering)
Hillary w2 Clinton (retrieves Hillary Clinton, Hillary Rodham Clinton, etc.)
n# = near
-
Near specifies that the words may appear in any order.
-
Substitute the # with a number of words that may appear in between.
-
Examples:
cloning n3 human (retrieves cloning of humans, human cloning etc.)
