This article will help you use the Build Your Own Segment Search Box on the Advanced Options section of LexisNexis Academic. The BYOSS area will help you construct a segment search in order to narrow your search in a very specific way. Segment searches bring back the most precise results. Note that if you are an experienced researcher and know many of these segments off hand, you can just type the entire segment into the main search box and forego the Advanced Options section.

==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.  
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.  
+
  
 +
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.
  
The example at right shows a segment search you might use to find articles from author David Pogue.  The full search string is: BYLINE(david w/3 pogue). This search string specifies search terms in the BYLINE segment. The "w/3" operator means that the terms "david" and "pogue" can be in any order but must be within three words of each other.
+
==Constructing a Segment Search==
 +
The Build Your Own Segment Search area consists of three elements:
 +
*The Segments Drop-Down Box
 +
*The Connector Buttons
 +
*The Building Box
  
 +
===Segments Drop-Down Box===
 +
First, 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.
  
You can enter a segment search by typing it directly into the "Search terms" box using the segment names shown below, or you can use the special tool provided on most search forms.  The tool is hidden by default. The box will automatically display when you select a source. Enter a search term or combination of terms and connectors, such as david w/3 pogue, in the "Terms" box and click the "Add to Search" button to insert the segment search into the "Search Terms" box at the top of the form with the appropriate parentheses and Boolean connector.
+
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:

However, if you just select one of the four, like Law Reviews, you will see the drop-down box change dramatically:

 +
===Connector Buttons===
 +
Besides the drop-down box of segments, the connector buttons allow you to use popular [[Boolean Searching]] connectors to construct a better search.
 +
*AND: returns documents that contain one search term and another search term
 +
*OR: returns documents that contain either one search term or another
 +
*AND NOT: returns documents that contain one search term, but not the other
 +
*w/5: returns documents that contain one search term within 5 words of another search term
 +
*w/p: returns documents that contain one search term within the same paragraph as another search term.
  
 +
===Building Box===
 +
The Building Box will display your search, as you use the Segments Drop-down and Connector Buttons. Think of the Building Box as a pre-search environment where you can construct your search. When you are finished with the construction, click apply. Once a user clicks apply, the contents of the Building Box will move directly into the Main Search Box:

<TABLE>
 +
<TR>
 +
<TD>[[Image: Segment1.jpg]]</TD>
 +
<TD>[[Image: Segment2.jpg]]</TD>
 +
</TR>
 +
</TABLE>
