How do you highlight searched words in results?

This is a simple matter of finding the text you are looking for, and replacing this text with a highlighted version of the same text. This can be accomplished using the replaceNoCase() function.

<cfset myText = "This is my text!">
<cfset myWord = "my">
<cfoutput>#replaceNoCase(myText,myWord,"<span style='background:yellow'>#myWord#</span>","all")#</cfoutput>

Also, Verity searches support this functionality right out of the box using the context column. In your Verity result set, the context column returns a context summary containing the search terms, highlighted in bold. (This is enabled if you set the contextpassages attribute to a number greater than zero.). If bolding your search term is not enough, you can use the contextHighlightBegin and contextHighlightEnd attributes to append custom HTML before and after your search term.
