New Search Help

Select Areas of the Site to Search

You can choose to search one or more areas of the site by checking the boxes to the left of the list of sections.

Choose Specific Keywords

Use specific words and make sure your keywords are spelled correctly.

Search for Exact Words or Phrases

If you are searching for an exact match, enclose your search in quotes. If you enclose your search in quotes you will only get results for the exact terms or phrase you entered in the exact order you entered them.

Examples of searching for an exact phrase:

  • "civil war maps"
  • "jackie robinson"
  • "declaration of independence"
  • "ice cream"

You can also search for an exact phrase and a keyword as in the following examples:

  • "civil war" maps
  • "abraham lincoln" funeral
  • farm "dust bowl"

Wild Cards

If you are not certain of the spelling of a word or if you would like to conduct a search on just part of a word or phrase, you can use a wild card. Enter the partial word or phrase and follow that directly with a question mark.

For example, the search fried? will return results that include the following words/phrases: Friedlander, Friedman, fried chicken, Frieda, etc.

Here is another example using a wild card with a phrase. A search for world war? will return results that include the following words/phrases: World War One, world wars, World War II, etc.

Boolean Operators

Boolean operators such as "and" and "or" are supported. Boolean operators must be entered in all lower case as in the following examples:

  • rodgers and hammerstein
  • labor or labour

The purpose of this new search tool is to expose users to resources from many areas of the Library. However, if you are certain you only want to search the Library’s Online Catalog or any of the other sources included in this search, you will experience greater search functionality from the individual sources themselves.

Punctuation

Most punctuation is ignored. Question marks are used as truncation devices as described above.
