Solr Facet for Event dates

Question

I have an event table which has start date and end date like this

==============================================
id   |   name       | start_date |  end_date
==============================================
1    | Test Event 1 | 2011-11-20 | 2011-12-20 
----------------------------------------------
2    | My Event 2   | 2011-12-05 | 2011-12-26 
----------------------------------------------
3    | My Event 3   | 2012-12-26 | 2012-01-11
----------------------------------------------

Now I want to have a solr facet which looks like this and i can't seem to get the params right.

==================
Dates 
------------------
Today [2]
This Week [2]
This Month [2]
Next Month [1]

Please note that the facet has to consider both start date and end date. Sort of gouping ?

What should be the faceting parameters for this ?

Thanks in advance for any help.

Answer 1

I finally got it working using solarium libraries Facet Multi Query based on the example http://wiki.solarium-project.org/index.php/V2:Facet_multiquery

The part in my Zend App looks like

$dateFacetSet = $query->getFacetSet();
$dateFacet = $dateFacetSet->createFacetMultiQuery('dates');
$dateFacet->createQuery('Today', 'type:event AND sdate:[* TO NOW/DAY] AND edate:[NOW/DAY TO * ]');
$dateFacet->createQuery('This-Week', 'type:event AND sdate:[* TO ' . $this->view->date_w["end"] . 'T23:59:59Z] AND edate:[' . $this->view->date_w["start"] . 'T00:00:00Z TO * ]');
$dateFacet->createQuery('This-Month', 'type:event AND sdate:[* TO ' . $this->view->date_m["end"] . 'T23:59:59Z] AND edate:[' . $this->view->date_m["start"] . 'T00:00:00Z TO * ]');

If anyone wants to know more, please let me know.

These params catch what i needed so far but haven't tested extensively.
