Subject [jira] Updated: (SOLR-792) Tree Faceting Component
Date Wed, 08 Sep 2010 21:54:50 GMT

     [ https://issues.apache.org/jira/browse/SOLR-792?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ryan McKinley updated SOLR-792:
-------------------------------

    Attachment: SOLR-792-PivotFaceting.patch

This takes the existing patch and:

# Renames TreeFacetCompont to 'PivotFacetComponent' (i like that name best)
# Moves the parameter defines to FacetParams.java
# Adds pivot support to Solrj so the fields are used easily
# Adds tests using the solrj API
# Augments the results with the matching facet count -- this is kind of hacky
 the name is is prefixed with its count, in the sample data, this is:
{code:xml}
<lst name="facet_pivot">
  <lst name="cat,popularity">
    <lst name="17:electronics">
      <int name="6">5</int>
      <int name="7">5</int>
      <int name="5">3</int>
       ...
      </lst
    <lst name="6:memory">
      <int name="5">3</int>
      <int name="7">2</int>
      ...
    </lst>
{code}
This means that there are 17 things matching electronics and 6 matching memory.

Anyone have better ideas how we could include this info?  I also considered:
{code:xml}
    <lst name="electronics">
      <int name="6">5</int>
      <int name="7">5</int>
      <int name="5">3</int>
       ...
      <int name="__count__">17</int>
     </lst
{code}
