Hey David,
thanks for the answer ..

ah.. you mean i should boost each field of the document? or is there a
way to set a boost level for the document as a whole? if so, i've missed
it ..

i like the idea of giving a short block with a sort algorithm.. i would
like to see something like that:
index.search ( :query => my_query,
:sort => Proc.new( |doc| # some caluclation; return
new_score ),
:reverse => false,
:filter => false,
:start => 0,
:limit => 10 )
alternativly you should be able to give the sort param a name of a
filed, like ':sort => :score' or an array of fields like ':sort => [
:score, :title ]' and sort by the first element and then by the 2nd if
the two or more docs share the same value for the 1st element.
I guess something like ":sort => :score" is enough for most people ..
i think the other options are almost like it is implemented right now ..
i don't think you nee the SortField class.
btw.. i do find the filter API not really intuitive, actually i didn't
understand it at all ;)
i know what you want to do with filters and how you want to get there,
but i haven't found any understandable documentation, on how to build
one ..
maybe you should write a short tutorial on how to write a filter.. i
would find it very intuitive, to have something like a base_query.. like
having one query to filter/limit results, and have another query to do
the real search..
and btw.. one feature i would definitely would like to see is to limit
the search on a number of fields..
i know i can write something like
field_one:"search string" || field_two:"search
string||field_three:"search string"||field_four:"search string"
but i would like to be able to write something like
(field_one|field_two|field_three|field_four):"search string"
furthermore, you should be able to say something like .. search in all
fields, except field_one .. like
(*|!field_one):"search string"
