Digg-like search result ranking with Lucene / Solr?
I'm using Solr for search. I have documents that have an integer field " popularity ". I want to rank results by a combination of normal fulltext search relevance and popularity. It's kinda like search in digg - result ranking is based on the search relevance as well as how many digs a posting has. I don't have any specific ranking algorithm in mind. But is this something that can be done with solr? Solr's FunctionQuery is exactly what you need: http://wiki.apache.org/solr/FunctionQuery 来源: https://stackoverflow.com/questions/1996668/digg-like-search-result-ranking-with-lucene-solr
