Apache Solr for TYPO3 CMS

Here is a patch that enables support for range facets using jQuery sliders.

This is usefull if you use index queues to index records with numeric values (think product dimensions or price).

1. Add fields to your solr schema file:

      <field name="height" type="sint" indexed="true" stored="true" />

Take note to use the sint, slong, sfloat and sdouble for numeric fields. Otherwise you will not be able to do range queries on the field

2. Add TypoScript configuration to index and facet the field

 plugin.tx_solr {
   search {
     faceting {
       facets {
         height
           label = Height
           field = height
           type = range
           range {
             gap = 1
             start = 0
             end = 100
           }
           renderer = tx_solr_facet_RangeFacetRenderer
           filterParser = tx_solr_query_filterparser_Range 
           renderingInstruction = TEXT
           renderingInstruction {
             field = optionValue
             noTrimWrap = |<img src="fileadmin/Images/Solr/Icons/height.png" title="height" /> ||
           }
         }
       }
     }
   }
   index.queue {
     pages = 1
     tx_someextension_domain_model_product = 0
     tx_someextension_domain_model_product {
       table = tx_someextension_domain_model_product
       fields {
         type = TEXT
         type.value = product
         stackable = COA
         stackable {
           5 = TEXT
           5.value = yes
           5.if.isTrue.field = stackable
           10 = TEXT
           10.value = no
           10.if.isFalse.field = stackable
         }
         height = COA
         height {
           5 = TEXT
           5.field = height
           5.if.isTrue.field = height
         }
       }
     }
   }
   _LOCAL_LANG {
     default {
       sorting_height = hoogte
     }
     en {
       sorting_height = height
     }
     nl < .default
  }
 }

3. Re-index
4. Profit!

There are three new files:

• classes/facet/class.tx_solr_facet_rangefacetrenderer.php
• resources/javascript/jquery-ui-1.8.16.custom.min.js
• resources/javascript/pi_results/range_facet.js

The jquery-ui includes the needed slider widget.
