Needs: I wan''to apply the solr query by keyword to a subgroups of
documents.
I''m putting on the index only title and content of each, is it
possibile to do something like this:
@articles = Article.find_by_solr(params[:query], {:scores => true, :id
=> [1,2,3]})
this above does not work, I get: "Invalid parameters: id"
it''s ok if u know any other way to obtain that. ;)
This is an example of xml result to a query:
<doc>
<float name="score">0.18781202</float>
-
<arr name="id">
<str>Article:77</str>
</arr>
-
<arr name="pk_i">
<int>77</int>
</arr>
</doc>
last possibility.. i''d need to force find_by_solr to filter using
"Article.id IN (?)", [1,2,3]
(or a variable of array..of course)

So in your example, you''d want something like: Article.scoped(:conditions => { :id => some_array_of_ids }).find_by_solr(...whatever you usually pass...) Note that this is not actually scoping the find_by_solr; it''s just scoping the results (find_by_solr gets an array of IDs back from Solr, then does a find(:all, :conditions => { :id => results }) which gets scoped. In your particular case (having a bunch of IDs to limit to), you could also use find_id_by_solr, like this: solr_ids = Article.find_ids_by_solr(....) @articles = Article.find(limit_ids & solr_ids) The other technique is much more generally applicable, whereas this ONLY works for limiting by ID. --Matt Jones

All of this of course is a matter on tons of records I need to solve (into studying area) the needs is that if I have only 5 ids to look keywords into..i don''t want to search all the index... and this happen anyway in the cases showned above :S thanks a lot!> > --Matt Jones
The big deal is that option only allowed RANGE and only OR chain..in fact this: find_by_solr "query-string AND (id:(1) OR id:(42))" work.. (so I''ve been told) and logically talking it does the right thing..in only search for query-string among the subset of ids.. but..is this the only way?..so ugly? the guy who tried this moreover said that this fails often in production..probably due to the high number of ids..
