how to sort by field (eg. rating) and if equal then by relevance (score)

[Muayyad AlSadi]

hi,

let's assume I have two fields book title and book rating

some one searched for "how to learn python programming" (with OR operator)
I want to give the user the option to sort by rating yet if both have same rating then to consider better match

[Matt Chaput]

This should work, assuming "rating" is a numeric field:

from whoosh import sorting

facet = sorting.MultiFacet(["rating", sorting.ScoreFacet()])
results = searcher.search(myquery, sortedby=facet)

Hope this helps :)

I probably should have reversed the rating field, assuming rating=5 is
better than rating=1...

facet = sorting.MultiFacet([sorting.FieldFacet("rating", reverse=True),
sorting.ScoreFacet()])

sortedby = []
sortedby.append(FieldFacet('rating', reverse=True))
sortedby.append(ScoreFacet())
results = searcher.search(myquery, sortedby=sortedby)

I meant to say how about using list like this

sortedby = []
sortedby.append(FieldFacet('rating', reverse=True))
sortedby.append(ScoreFacet())
results = searcher.search(myquery, sortedby=sortedby)

what is the difference between the two

There should be no difference... if you pass a list to sortedby Whoosh
will automatically wrap it with a MultiFacet object.
