Erik,
> Nice to see you here! I have recently noticed your work with Flare
and been very pleased to see someone give it a try besides myself :)
I'm pleased to see you here, too!
Struggling a few hours, I can implement facet.query feature on my demo:
http://www.rondhuit-demo.com/yademo/
Here is what I did:
1. rename "facet_queries" to "saved_queries" and
"applied_facet_queries" to "applied_saved_queries"
(Why I did this because first I used @facet_queries to have
facet.query and it was success except that facet query links
were displayed at "saved searches" area)
2. initialize @facet_queries by having:
@flare.facet_queries = {
'1-1,000'=>{:queries=>[{:query=>'price:[1 TO 1000]'}],:filters=>[]},
'1,001-5,000'=>{:queries=>[{:query=>'price:[1001 TO
5000]'}],:filters=>[]},
'5,001-10,000'=>{:queries=>[{:query=>'price:[5,001 TO
10000]'}],:filters=>[]},
'10,001-20,000'=>{:queries=>[{:query=>'price:[10,001 TO
20000]'}],:filters=>[]},
'20,001-'=>{:queries=>[{:query=>'price:[20001 TO *]'}],:filters=>[]}
}
3. have the following in search() method:
facet_queries = @facet_queries.collect do |k,v|
clauses = filter_queries(v[:filters])
clauses << build_boolean_query(v[:queries])
query = clauses.join(" AND ")
@facet_queries[k][:real_query] = query
query
end
4. and use the above with saved_queries when assembling solr_params:
# :queries => saved_queries
:queries => saved_queries.concat(facet_queries)
5. have the following "price facet" display in browse/index.rhtml:
<h4>
price
</h4>
<ul>
<% @flare.facet_queries.each do |name,value|
count =
@response.data['facet_counts']['facet_queries'][value[:real_query]]
if count > 0
field_value = value[:queries][0][:query]
%>
<li>
<%= image_tag "pie_#{(count * 100.0 / @response.total_hits).ceil
rescue 0}.png"%>
<%= link_to "#{name} (#{count})", :action => 'add_filter',
:field=>field_value.sub(/:.*$/,''), :value=>field_value.sub(/^.*:/,'')%>
</li>
<% end %>
<% end %>
</ul>
6. finally, I have to change filter_queries() method as follows to avoid
NumberFormatException
when clicking one of price facet
link(java.lang.NumberFormatException: For input string: \"[10001 TO
20000]\"):
# value = "\"#{value}\""
value = "#{value}"
Next, I'll have date faceting feature to the demo. Also, the price facet
links should be sorted.
Thank you again, Erik!
