    <p>I'm trying to retrieve a list of the top tags for a User using ElasticSearch and Tire. </p> <p>I've seen <a href="http://www.elasticsearch.org/blog/2011/05/13/data-visualization-with-elasticsearch-and-protovis.html" rel="nofollow">this article</a> floating around, however it doesn't completely work in my situation.</p> <p>I need to filter by a user_id, and am aiming not to get hits returned at all. I haven't found a way of getting this to work with Tire.</p> <p>I have tried the following:</p> <pre><code>Tire.search 'bookmarks' do |s| s.query { all } s.facet 'tags', facet_filter: { term: { user_id: 1 } } do terms :tags, all_terms: true end end </code></pre> <p>Help is appreciated, thank you.</p> <p><strong>EDIT:</strong> Using the code above, the following output is returned.</p> <pre><code>=&gt; #&lt;Tire::Search::Search:0x007fd4b0bed110 @indices=["bookmarks"], @types=[], @options={}, @path="/bookmarks/_search", @query=#&lt;Tire::Search::Query:0x007fd4b0bec5d0 @value={:match_all=&gt;{}}&gt;, @facets={"tags"=&gt;{:terms=&gt;{:field=&gt;:tags, :size=&gt;10, :all_terms=&gt;true}, :facet_filter=&gt;{:term=&gt;{:user_id=&gt;1}}}}&gt; </code></pre> <p><strong>EDIT 2:</strong> I've accomplished what I was trying to do with the following code:</p> <pre><code># Public: Returns an array of hashes, which includes the user's top # tags and a number of items in those tags. # # Format follows: # [{'term' =&gt; 'Some Tag', 'count' =&gt; 123}, {'term' =&gt; 'Another Tag', 'count' =&gt; 321}] # def self.top_tag_count(user_id, number_of_tags=10) top_tags = tire.search search_type: 'count' do |s| s.query { all } s.filter :term, user_id: [user_id] s.facet 'tags', global: true do terms :tags, size: number_of_tags end end top_tags.facets['tags']['terms'] end </code></pre>

    2. CO"am aiming not to get hits returned at all" – What I meant was that, ideally, I'd not like ElasticSearch to return copies of my model (Bookmark) in the results. Although I don't know if this is possible or not.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
