Drupal search results filter, similar to drupal.org's search results page

Pretty new to drupal and I want to create a search results page that includes a filter, just like the one used on drupal.org (http://drupal.org/search/apachesolr_multisitesearch/test).

I've looked around for a module to do this, but haven't been able to locate one. Perhaps I'm not searching for the correct terms, but I've开发者_如何学Python not had any luck.

Incase it matters, I have many nodes of content that are attached to a taxonomy of terms called "Tags" - I'd like to have the filter update the list of results based on the user selecting which "terms" to remove.

How are you accomplishing this? TIA!

Edit:

Throwing in my install instructions for future travels:

• Goto the following website: https://hudson.apache.org/hudson/job/Solr-trunk/lastSuccessfulBuild/artifact/checkout/solr/dist/ And find the nightly (Today’s date) build and download it.

• Expand and rename the downloaded folder as “apache-solr-nightly”. This should NOT live in your webroot.

• Download the zip here: http://solr-php-client.googlecode.com/files/SolrPhpClient.r22.2009-11-09.zip and unzip the file.

• Download the zip here: http://ftp.drupal.org/files/projects/apachesolr-6.x-1.2.zip (Or the most current 6.x version) and unzip the file.

• Copy the schema.xml from the apachesolr-6.x-1.2/ that was just unzipped to the apache-solr-nightly/example/solr/conf

• Copy the solrconfig.xml from apachesolr-6.x.1.2/ to apache-solr-nightly/example/solr/conf

• Edit the solrconfig.xml and include the following line as a child of

<luceneMatchVersion>LUCENE_40</luceneMatchVersion>

• Search for and comment out the following lines

  <queryResponseWriter name="xslt" class="org.apache.solr.request.XSLTResponseWriter"> <int name="xsltCacheLifetimeSeconds">5 </queryResponseWriter>

• Change to the apache-solr-nightly/example directory and execute the solr jar java -jar start.jar

drupal.org uses Apache Solr Search Integration (together with Apache Solr, of course).
