Serious bug: OutOfMemoryError: Java heap space
Nutch 0.6 throws the following exception when the
search phrase includes just a single quote. Something
like "java or ja"va.
Here is the exception:

I found that it happens because a bug in the following infinite
loop in the NutchAnalysis class.
label_4:
while (true) {
switch ((jj_ntk==-1)?jj_ntk():jj_ntk) {
case 0:
case PLUS:
case MINUS:
case COLON:
case SLASH:
case DOT:
case ATSIGN:
case APOSTROPHE:
case WHITE:
;
break;
default:
jj_la1[6] = jj_gen;
break label_4;
}
nonTerm();
}
It seems that this class was generated using JavaCC. Could
anybody who knows how to use this tool fix the problem?

---------------------------------------
Some time ago I sent a patch for this with JUnit test on the list - but it was using old package naming. I had plans to resubmit it last week but due to amount of other work I have posponed it. Anyway there is one difference between your and mine solution:
I have added one additional method:
void nonTermOrEOF() :
{}
{
nonTerm() | <EOF>
}
and changed:
/** Parse anything but a term or an operator (plur or minus or quote). */
void nonOpOrTerm() :
{}
{
(LOOKAHEAD(2) (<WHITE> | nonOpInfix() | ((<PLUS>|<MINUS>) nonTerm())))*
}
into
/** Parse anything but a term or an operator (plur or minus or quote). */
void nonOpOrTerm() :
{}
{
(LOOKAHEAD(2) (<WHITE> | nonOpInfix() | ((<PLUS>|<MINUS>) nonTermOrEOF())))*
}
My solution allows to parse:
"test +" query as "test"
in your case such query throws parse exception.
I can send the patch again if you wish so we can merge our versions. I will have a look at Junit tests too, to see if they can/should be merged.

---------------------------------------
Thanks for integrating my suggestion. After reviewing my tests I think two really minor things might be added to JUnit test:
assertQueryEquals("\" abc def \" \" def ghi ","\"abc def\" \"def ghi\""); //missing fourth double quote
assertQueryEquals("\"",""); //empty query
The rest works perfectly for me.

Just wanted to add that when the search phrase includes
just one quote symbol then Nutch takes 100% of CPU for a
few seconds, eats all available RAM, and then throws this
OutOfMemoryError exception.

Re: Highlighting query words in cached html
Posted by 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><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:)

Highlighting query words in cached html
Posted by "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
