When I started looking at distributed search, I immediately went and read the map-reduce paper (easier concept than it first appeared), and realized it's really more for the indexing side of things (big batch jobs, making data from data, etc). Nutch uses map reduce for crawling/indexing, but not for querying.
Yes, nutch use map reduce only for crawling/indexing, not for querying. http://www.nabble.com/something-i-think-important-and-should-be-added-tf3813838.html#a10796136 map-reduce just for indexing to decrease "Master solr query *instance" *index size and increase query speed. It will cost many time to index and merge but it will increase query accuracy. index and data not in same box. so we just only sure master query server hardware is powerful and slave query server hardware is not very important. Master index server should support multi index. If solr support it. I think user who use solr will quick setup their search. It just my thought. how do u think, yonik,,,and how do u think next solr? -Yonik
