I don't know exactly what you are wanting to do below. Adding a term
through a query filter would be something like this:
import org.apache.nutch.searcher.FieldQueryFilter;
import org.apache.hadoop.conf.Configuration;
public class NewQueryFilter
extends FieldQueryFilter {
public CategoryQueryFilter() {
super("term");
}
public void setConf(Configuration conf) {
super.setConf(conf);
}
}
Searching would be in its own code usually being called through a
servlet or jsp page. The reason eclipse isn't happy
is because the code below needs to be inside of a method like so:
public class Search {
public static void main(String[] args) {
Query query = new Query();
query.addRequiredTerm("term");
Configuration conf = NutchConfiguration.create();
IndexSearcher searcher = new IndexSearcher(new
Path("C:\\path\\to\\index"), conf);
NutchBean bean = new NutchBean(conf);
Hits hits = bean.search(query, 10);
HitDetails[] details =
searcher.getDetails(hits.getHits(0,hits.getLength()));
for (int i = 0; i < details.length; i++) {
HitDetails curDetail = details[i];
System.out.println(curDetail);
}
}
}

Hi Dennis,
Sorry to disturb you again but I reaaly cannot get this code working...
should I put the code you gave me in a classe extending BasicQueryFilter?
Here is my code in its simplest form:
public class Search extends BasicQueryFilter{
{try{
Query query = new Query();
query.addRequiredTerm("term");
Configuration conf = NutchConfiguration.create();
IndexSearcher searcher = new IndexSearcher(new
Path("C:\\path\\to\\index"), conf);
NutchBean bean = new NutchBean(conf);
Hits hits = bean.search(query, 10);
HitDetails[] details =
searcher.getDetails(hits.getHits(0,hits.getLength()));
for (int i = 0; i < details.length; i++) {
HitDetails curDetail = details[i];
System.out.println(curDetail);
}
}
catch (IOException e) {
e.printStackTrace();
}
}}
Still, eclipse is not happy, asking to add a { before the try, why???...........
HELP! :D
Hope
you can help me solving this problem...
Thanks a lot

Try something like this. The conf folder holding the nutch-site.xml and
hadoop-site.xml file must be in the classpath here. I have the file
system set to local and I have an index on the local filesystem.

try {
Scanner scanner = new Scanner(new File("C:\\d01\\searchterms.txt"));
Query query = new Query();
while (scanner.hasNext()) {
query.addRequiredTerm(scanner.nextLine().trim());
}
Configuration conf =
NutchConfiguration.create();
IndexSearcher searcher = new IndexSearcher(new
Path("C:\\d01\\crawl3\\index"), conf);
NutchBean bean = new NutchBean(conf);
Hits hits = bean.search(query, 10);
HitDetails[] details = searcher.getDetails(hits.getHits(0,
hits.getLength()));
for (int i = 0; i < details.length; i++) {
HitDetails curDetail = details[i];
System.out.println(curDetail);
}
}
catch (IOException e) {
e.printStackTrace();
}
