Removing single-term results / reordering

[Fuad Efendi <fu...@efendi.ca>]

Hi, 
I execute query "word1", and it returns 100k results where top-10k are just
"word1".
How to filter it, and to show "word1 word2" in top-10?
Thanks

Hi Jan,

I believe Yonik already answered on such question, it is simply schema
configuration / specific query type; but I can't find this post...
Something like [product:word1 -product:"word1"], but I am under liters of
beer :) and can't think...

Hi,

This is probably due to length normalization. Normally this is wanted, as you want to penalize partial match vs a more exact match.
Try specifying omitNorms=true on your field.

You should ask yourself what kind of relevancy or sorting you really need in your project. If you search short fields of structyred data, you may not need any of the default relevancy stuff but construct your own based on some other criterias?
