Hi,
Since I ran into SOLR project the other day I was wandering that
maybe SOLR
could be Nutch's SE...
We've been using it since I realized we could not get the Lucene
queries we wanted out of the Nutch OpenSearch SE. Solr also
integrates a lot better with back end development as it outputs in
JSON, XML and Python. It's even more valuable with Sami's SolrIndexer
patch that he has on his blog-- Nutch indexing now goes straight to
Solr. It's very fast and so far robust -- I've lazily crawled 600K
pages on a single CPU (with stored content!) in the past few days
after integrating Sami's stuff with no obvious problems yet.
From what I can tell, you lose some of the advanced Nutch scoring
features. We get the document boost (Sami, I owe you a patch) but
that's about it. The Nutch SE is also a great "Google in a Box" setup
for people that want that. For that reason I am not so sure Solr
should replace Nutch's SE. Solr is more useful for people that want
to do something programatically or queries more complex than "AND"
with the Nutch. There's no search front end in Solr other than the
admin interface.
Would love to see Sami's patch in trunk as an indexing plugin, though.
