hi all ,
I have a problem that how to "combine" two score to sort the search
for example I have 10 million pages in lucene index , and i know their
pagerank scores. i give a query to it , every docs returned have a
lucene-score, mark it as R (relevant score), and i also have its
pagerank score, mark it as P, what i need is i want to sort the search
result base on the value "P+R". You know if i store the pagerank score in
index and get it every search time , then compute P+R , then sort it , this
way is too slow. in my system , when the search hits 500000 result , the
sort may cost about 20s.
Sorry for my poor english. Anyone has a good idea?
