Hi,
After I merged indexes from the directory /home/nutch/segmetns which contains
20 sub directories. My outputIndex name is index. Then, I moved the index under
/home/nutch/merged_index/. In the nutch-site.xml, I set 'searcher.dir' to be '
/home/nutch/merged_index'. After that, I restarted tomcat. When I did a search,
I got error:
