Re: score from two cores
A common problem in metasearch engines. Its not intractable. You just have to surface the right statistics into a 'fusion' scorer. - NOT always nice.

I don't know why the OP wants two cores, but I ran into this same problem and had to abandon using a second core. My use case is: I have lots of slowing-changing documents, and a few often-changing documents. Those classes of documents are updated by different people using different processes. I wanted to split them into separate cores so that: 1) The large core wouldn't change except deliberately so there would be less chance of a bug creeping in. Also, that core is the same on different servers, so they could be replicated. 2) The small core would update and optimize quickly and the data in it is different on different servers. The problem is that the search results should return relevancy as if there were only one core.
Re: score from two cores
The scores will not be comparable. Scores are only relevant within one search on one core, so comparing them across two queries (even if it's the same query but against two different cores) is meaningless. So, given your setup I would just use the results from one of the cores and fill in data from the other... But why do you have two cores in the first place? Is it really necessary or is it just making things more complex?

RE: score from two cores
Please correct me if I am doing something wrong. I really appreciate your help! I have a core for metadata (xml files) and a core for pdf documents. Sometimes I need search them separately, sometimes I need search both of them together. There is the same key which is related them for each item. For example, the xml files look like following: rmaaac.pdf something rmaaac . I index rmaaac.pdf file with same Key and UI field in another core. Here is the example after I index rmaaac.pdf. 0 3 on 0 collectionid: RM 10 2.2 rm rm.pdf something The result information which is display to user comes from metadata, not from pdf files. If I search a term from documents, in order to display search results to user, I have to get Keys from documents and then redo search from metadata. Then score is different. Please give me some suggestions!

Uhhm, what are you trying to do? What do you want to do with the scores from two cores? Best Erick On Fri, Dec 3, 2010 at 11:21 AM, Ma, Xiaohui (NIH/NLM/LHC) [C] < xiao...@mail.nlm.nih.gov> wrote: > I have multiple cores. How can I deal with score? > > Thanks so much for help! > Xiaohui >
