Re: pagerank??

According to my knowledge, Solr cannot support this. In my case, I get data by keyword-matching from Solr and then rank the data by PageRank after that. Thanks, Bing On Wed, Apr 4, 2012 at 6:37 AM, Manuel Antonio Novoa Proenza < mano...@estudiantes.uci.cu> wrote: > Hello, > > I have in my Solr

How is Data Indexed in HBase?

Dear all, I wonder how data in HBase is indexed? Now Solr is used in my system because data is managed in inverted index. Such an index is suitable to retrieve unstructured and huge amount of data. How does HBase deal with the issue? May I replaced Solr with HBase? Thanks so much! Best regards,
