Phrase searching

A phrase is a group of two or more words that express a single idea or meaning, when written next to each other.

Phrase searching means searching a database for words together, in a precise order.

By the general rules, the way to search for terms next to each other is to enclose them in quotation marks:

“global warming”, “coastal marine fish”

A phrase searching helps to screen out the cases, where the words occurring together is essential to the meaning of a search term.

A good example is “forest management”: ‘a branch of forestry concerned with overall administrative, economic, legal, and social aspects, as well as scientific and technical aspects, such as silviculture, protection, and forest regulation’ (definition from Wikipedia).

Interactions between windthrow, bark beetles and forest management in the Tatra national parks

The meaning of the phrase is lost, if the words don’t appear together:

Divergent trends in ecosystem services under different climate-management futures in a fire-prone forest landscape

So a phrase searching is very useful but also a restricting search tool. The number of results usually decreases if you use a phrase.

Text and pictures of piles of books, symbolizing the number of results. “Forest soil”, enclosed in quotation marks, 41 results, a small pile. Forest soil, without quotation marks, 386 results, a bigger pile. Forest AND soil, 386 results, the same size of  the pile as the former one.
See an example how using a phrase affects the number of results. Notice that two words without truncation marks are the same as AND-command between the words.

Using a phrase is sometimes a good41way to get rid of irrelevant results. But it is good to be aware, that it might leave also something useful out from the result. There might be some extra terms in the middle of the “basic” phrase or the phrase can be written with of-expression, for instance.

To Do:

  1. Figure out, which of your search terms might be used as a phrase
  2. Recognise alternative ways of expressing your phrases
  3. Place quotation marks around phrases
  4. Prepare to give up your phrases, if they turn out to be too restricting
