How do I get lucene to score a given document

[江梓涵 <ji...@ict.ac.cn>]

Hello, I am a student of Chinese Academy of Sciences. Search engine that based on lucene is an important part of our experiment. My question is how can I get lucene to score the given documents. For example, I just want lucene to score the document in the given docId set. As far as i know, Lucene will score all relevant documents in each query. I try to use filterQuery, but It increased the cost of time. 

Waiting for your kind help. Thanks!

Hi,

There is an explain functionality for single documents available for that. Check IndexSearcher.explain(). Otherwise a filter is your only chance. It should not be slow, as selective filters (applied with BooleanClause.Occur.FILTER, maybe your filter is the problem: if you have many IDs to limit on, use Term*s*Filter/Term*s*Query)?
