Hi!
Hi,
I know there is a MultiSearcher class, but it seems that Nutch is using a
very different index layout than Lucene, or am I wrong here?
Nutch uses lucene as an inverted index. Lucene does not have an index
structure. You create the structure
(I mean the fields) using lucene. Nutch stores some default fields in
the index as well as extra fields from index
plugins. You can check out the structure of the index from the wiki :
http://wiki.apache.org/nutch/IndexStructure
What you should do is to compare the structure nutch uses with the
structure you use, and somehow combine the two. In most of the fields,
you sould converge to the nutch version. Other than that, once index the
index is created from nutch, it is lucene stuff. You can merge the
indexes or run a MultiSearcher, or open seperate
DistributedSearch$Clients and combine the results from seperate indexes
on the fly. However there is an issue about summaries. Do you intend to
use them?
My end goal is
a list of results with the most relevant hits from both indexes at the top
positions.
How would you go about this?
Thanks a lot for your input!
Regards,
Michael
