Search Tips and Search Modification

To ensure you get the best and most relevant results for every search on the NIA website, the search tool allows for search modification (this is a feature of the latest generation of search engines, such as Google or Bing). This allows you to narrow down the results of the search term by using the following techniques:

A phrase that is enclosed within double quote (""") characters matches only rows that contain the phrase literally, as it was typed. Nonword characters need not be matched exactly: Phrase searching requires only that matches contain exactly the same words as the phrase and in the same order. For example, "test phrase" matches "test, phrase".

How to Use Search Modification

The following examples demonstrate some search strings that use search modification:

'apple banana'

Find rows that contain at least one of the two words.

'+apple +juice'

Find rows that contain both words.

'+apple macintosh'

Find rows that contain the word "apple", but rank rows higher if they also contain "macintosh".

'+apple -macintosh'

Find rows that contain the word "apple" but not "macintosh".

'+apple ~macintosh'

Find rows that contain the word "apple", but if the row also contains the word "macintosh", rate it lower than if row does not. This is "softer" than a search for '+apple -macintosh', for which the presence of "macintosh" causes the row not to be returned at all.

'+apple +(>turnover

Find rows that contain the words "apple" and "turnover", or "apple" and "strudel" (in any order), but rank "apple turnover" higher than "apple strudel".

'apple*'

Find rows that contain words such as "apple", "apples", "applesauce", or "applet".

'"some words"'

Find rows that contain the exact phrase "some words" (for example, rows that contain "some words of wisdom" but not "some noise words"). Note that the """ characters that enclose the phrase are operator characters that delimit the phrase. They are not the quotation marks that enclose the search string itself.           

Why not try using Search Modification in your next search? You'll find the results should be a lot more precisely targetted to your specific query.
