==What is a Segment?==
 
==What is a Segment?==
A document section is an element within the document such as "Byline", "Date", etc. These sections are useful when you need to narrow your search to something very specific, like an author's name or a word in the headline. This kind of searching is often called "fielded" or "faceted" searching.

A document segment or section is an element within the document such as "Byline", "Date", etc. These sections identify certain parts of the document. Segment searches are useful when you need to narrow your search to something very specific, like an author's name or a word in the headline. This kind of searching is often called "fielded" or "faceted" searching. Instead of searching all of the text inside a document, you may find it very useful to only search within a segment of the document for better results.

For example, if you would like to find articles from a specific author, like David Pogue, use the BYOSS box to search within the BYLINE() segment instead of the entire document. That way, you will only see articles written by David Pogue and not articles that mention the name David Pogue somewhere in the document. Also, searching for a specific phrase in the HEADLINE segment will only bring back articles with that phrase in the headline, not articles that include that phrase in any part of the document.

It is very important that you select a source before you start working with the Build Your Own Segment Search box. The drop-down box with all of the segments will refresh based on the sources that have been selected. In the case that more than one source is selected, the drop-down box will only show the segments that the various sources have in common.

For example, on the Main Page's BYOSS box, there are four different sources selected. Furthermore, these four sources are all very different types of content. So, it makes sense that the default BYOSS box contains a very small amount of segments in common:

Segments can only be used in the "Terms and Connectors" (Boolean) search mode or on the News or PowerSearch form. The format for specifying a segment search is:  SEGMENT-NAME (search terms). You can use [[Boolean Searching|Boolean operators and LexisNexis connectors]] to combine multiple segment searches and regular full-text search terms.
