Re: Highlighting query words in cached html

[Jack Tang <hi...@gmail.com>]

Hi Ferenc

It is not tha answer to your question. But I have extract highlighting
query words in summaries. Here are what I have done:


---------- Configuration file(nutch-site.xml)------------------
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="nutch-conf.xsl"?>

<!-- Put site-specific property overrides in this file. -->

<nutch-conf>

	<!-- terms highlight style -->
	<property>
	  <name>summary.fragment.highlight.exp</name>
	  <value>token</value>
	  <description>Default is '%token%'. The term name(expression) that 
	   will be used in highlight style.</description>
	</property>
	<property>
	  <name>summary.fragment.highlight.style</name>
	  <value>&lt;font color="red"&gt;token&lt;/font&gt;</value>
	  <description>Default is '&lt;b&gt;%token%&lt;/b&gt;'. The style of 
	  highlight in summary. </description>
	</property>

</nutch-conf>
 
-------- Change code in Summary.java-------------
toString() method in innner class Highlight.
- return "<b>" + super.toString() + "</b>";

+ NutchConf conf = NutchConf.get();
+ String termName = conf.get("summary.fragment.highlight.exp","%token%");
+ String style    =
conf.get("summary.fragment.highlight.style","<b>%token%</b>");
+  	
+ return style.replaceAll(termName,super.toString());

In future, you can write some JavaScript to turn on/off the highlight:)

Regards

Highlighting query words in cached html

["yoursoft@freemail.hu" <yo...@freemail.hu>]

Dear Guys,

I would like highlight searched words in cached html content (like as 
google).
I have a problem with it:
If query like eg.: window, and I have a javascript in the html with eg. 
window.open, and I change the content all words with "window", this will 
broke the cached content. I need only change  the 'text'  content of 
cached html.
Can anyone to a idea how to make it?

Best Regards,
    Ferenc
