Hi all, Can anyone provide some insight as to how we might be able to make some tweaks to the relevance ranking using the new rank_cd() method? We have noticed an issue in one of our systems with 2.2 alpha1 where brief bib records tend to appear first in a list of search results. After reading through the documentation in the opensrf.xml file (BTW - I love the level of documentation that is provided here!), I removed #CD_documentLength from the list of default CD modifiers so that it now reads:
<default_CD_modifiers>#CD_meanHarmonic #CD_uniqueWords</default_CD_modifiers> However, those brief bib records still keep floating to the top of search results. I understand why you might want to reduce the relevancy for longer documents when you are doing full-text searches, but I'm not sure the same reasoning should be applied when searching metadata in MARC records. Has anyone else encountered similar problems with brief bib records? Has anyone made successful tweaks to the relevance ranking that they would be willing to share with the list? Thank you!
