Hello everyone,
because of the large amount of data we have to index, we do not create
one large index but instead multiple small indices (we call them
volumes) which will then be put on multiple servers (our search cluster).
If I understand Lucene's scoring correctly, I am not able to compare the
scores returned by the same query executed on multiple indices, because
there are factors affecting scoring which are different in each index.
Is that right?
If so, lets say I execute a search on Index A and Index B. A returns a
document with score 10 and B returns a document with score 8. If I am
not wrong, the above would mean that the document from B with score 8
can be a better match than the document from A with score 10.
Is that right?
If so, what can I do to make the scores from multiple indices comparable?
Best regards,
Sven Teichmann
