Hi,
I think i'm reading he question differently then Grant -- his suggestion
applies when you are searching in the description field, and don't want
documents with shorter descriptions to score higher when the same terms
match the same number of times (the default behavior of lengthNorm)
my udnerstanding is that you want documents that don't have a description
to score lower then documents that do -- and you might be querying against
completely differnet fields (description might not even be indexed)
in that case there is no easy way to to achieve this with just the
description field ... the easy thing to do is to index a boolean
"has_description" field and then incorporate that into your query (or as
the input to a function query)
You get my point Hoss. In my case long description = good value. And
your intuition is amazing ;-) I do have a field which is not used in
search at all (image url) but docs with image have for me greater value
than without it.
I would add two fields then (boolean for photo and int for description
length) fill them up during indexation and would play with them during
the search.
Thanks,
Tom
