Question: multiple editions #595

Closed merisjames closed 8 years ago

merisjames commented 9 years ago

How are the rankings of multiple editions determined? Searching for "hogg constitutional law", the various (student) editions appear in order 1999, 2002, 2007, 2005, 2009, 2011, 2013.

Ranking is always done on the basis of a relevance algorithm: it looks at which search terms appear in which data fields and constructs a score for each record (and breaks ties when necessary). The weighting of each field is specified in Blacklight's index configuration files.

I should specify that this is true for multiple editions of the same title as it is for different titles. To Blacklight, multiple editions are not connected in any way - they are different titles that happen to share metadata (and thus have similar relevance scores).
