Re: Highlighting query words in cached html
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><font color="red">token</font></value>
<description>Default is '<b>%token%</b>'. 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:)
