Tips for successfull searches
Here are some helpful tips to keep in mind when you are searching in NLM Finding Aids
String matching: The search engine uses string matching to determine search hits. That means, for each query term, the primary rule is this: what you put in the form text box is literally what the search engine will look for. This includes complete phrases. Exceptions to the primary rule follow ...
Term expansion: You can use an asterisk (*) at the end of a word stem to find plural forms and other variations on that word.Example: searching for "work*" will match works, worker, working, etc.
Punctuation: All punctuation marks entered in a search box are ignored and treated as spaces.Example: searching for anti-slavery and anti slavery will match both phrases.
Capitalization: Case sensitivity of the search term is not retained in searches by the search engine.Example: searching for Love will match "LOVE," "Love," and "love."
Other helpful tips:
Select specific areas of a text: Most of the search forms have pull-down menus that allow you to specify specific areas, or regions, of a text to search within.
If you are searching more than one collection simultaneously, the items in the menu can change depending on what collections you have selected. A general rule of thumb is: the more collections you select, the fewer region options will be available to search in. See a "glossary of search regions."
Click the search button: Not all browsers will allow you to submit any search form by hitting the enter or return key. This is especially the case for forms with more than one input text box. To be safe, click the search button.
