You can use the advanced search mode to search for your terms in the subject field. When you want to combine search terms, you will need to use what are called Boolean operators or connectors. This is best done using the advanced search mode. Next, you need to connect these two terms with a Boolean operator.

Using the operator AND will retrieve articles that mention both terms somewhere in the article. Using the operator OR between the two terms will retrieve articles that mention either term.

In this case, AND is the appropriate connector because you want to retrieve articles that address both concepts, combat and obesity. The use of AND generally will retrieve a smaller set of results.

Use of Boolean operators allows you considerable flexibility in your search. As another example, if you wanted to retrieve articles that dealt with either obesity or over weight, then the appropriate Boolean operator is OR.

The search obesity OR overweight will retrieve articles that mention either term. The use of OR generally will retrieve a larger set of results. OR is especially useful when you are searching with terms that are synonyms or that deal with the same basic concept.

Using the OR in your search will retrieve articles that contain any of the synonyms that you use. If you wanted to exclude terms , you would use the Boolean operator NOT. For example, if you were interested in the subject obesity, but not interested in how fast-foods relate to obesity, you could exclude all items that have the term fast-foods by searching obesity NOT fast-foods. Effective use of Boolean operators is essential to sophisticated research.

Truncate search terms to retrieve all variants of a term. Truncation symbols vary from database to database. Using the truncation symbol will allow you to broaden your search to include materials on any variant of a term. Most database search interfaces are not sophisticated enough to search for all variants of a term automatically. Most databases have limiting features that will let you focus the results of your search. You may be able to limit your searches to retrieve only scholarly or peer-reviewed articles.

You can also limit to particular date ranges or particular journals. Many databases provide their own unique limiters, which allow you to limit by intended audience, item type peer reviewed, journal or newspaper article , language, country of publication and more.

Limiting your searches will allow you to narrow your search, resulting in a smaller list of more relevant materials. There will never be one perfect search for your topic.
