Hi,

Facets don't work on ezfind for eZ Publish 4.7.0-dev.
I tried in the following situations:

• Installed ez publish 3.6 with ezfind 2.6.0 - facets worked as expected
• Installed ez publish 3.6 with ezfind 2.7.0-dev - facets worked as expected

• Latest testsystem with ezfind 2.6.0 and solr 3.1 - facets doesn't work
• Latest testsystem with ezfind 2.7.0-dev - facets doesn't work
• install ezpublish 4.7 using install_packages script, with ezfind2.7.0-dev - facets doesn't work

  Steps to reproduce

  Install ezfind extension following the INSTALL instructions
  Enable solr.sh

test (on ez flow):
- On frontend, create a folder "Folder1"
- Access Folder 1
- Create 2 articles ("Article 1" and "Article 2")
- Edit front homepage of ezflow
- Add a "Search" block enabling the "show-facets" checkbox
- On search box from the block we just added, enter the "Article" word and press the "search" button
- The result is shown without facets - error
