Having developed a search strategy you are now ready to enter it into the index or catalog you have selected to search. A sample search box from an index is shown above. To enter your search strategy use the following general search tips in addition to using the specific instructions for inputting keywords in the specific database you are searching.

If this initial search retrieves only a few references, just browse through them and identify the references relevant to your topic. If your search retrieves many references, repeat your search and add another concept using the AND boolean connector to decrease your results.

If you do not know what "controlled" keyword(s) to use, conduct an initial search using the keyword(s) you have. In reviewing your search results look for "controlled" keywords, often called descriptors or subject headings, which commonly appear as part of each citation description. Then repeat your search with the addition of these "controlled" keywords.
