I just recently switched to ThinkingSphinx from Ultrasphinx (and
before that acts_as_sphinx). Ultrasphinx worked great but had just a
couple issues that ThinkingSphinx resolves. Most notably the multi-
valued field support. One feature of Ultrasphinx I ported over to
ThinkingSphinx is the ability to generate facets for your attributes.
It requires an additional sphinx call per attribute but in my
experience it is very fast.
I am posting this patch to the group in hopes that this could be
rolled into ThinkingSphinx or at least be useful for others. I am
currently loading this using a Rails initializer. Comments and
improvements are welcome:.
Here is the code for facets:
require 'thinking_sphinx'
module ThinkingSphinx
class Search
class << self
# Add facet support
def facets(query, attrs, options={})
options.merge!({:group_function => :attr, :group_clauses =>
"@count desc"})
attrs = [attrs] unless attrs.is_a? Array
attr_facets = {}
attrs.each do |attr|
options[:group_by]=attr
results, client = search_results(query, options)
facets = {}
results[:matches].each {|e| facets[e[:attributes]
['@groupby']]=e[:attributes]['@count']}
attr_facets[attr] = facets
end
attr_facets
end
end
end
end
Thanks for that code - I've had a couple of other people request the facets feature. When I'm more awake I'll actually pay attention to the code and try to wrap it in to trunk.
