Facets and Apache Solr in Drupal 7 - Clicking Facets results in no results being show I'm having a bit of an issue with Facets and Apache Solr, I'm not sure whether the fault lies with Solr or the Facets API.

I am using Solr as my search engine and I get results being shown when searches are performed, also shown are the amount of matches in specified fields/facets. 

E.g. I search for 'content' - there are numerous values for 'content' within different categories such as 'category1', 'category2' 

The search result shows as:

category1(5)
category2(7)


Implying there are 5 results in the facet category1, and 7 results in the facet category2, these are also links, however upon clicking these links the search shows as "no results found". Odd behaviour, has anyone experienced anything like this before? if so any pointers on where to look in order to resolve the issue?

I'm hoping this question is quite clear, if not just ask and I'll try provide some more details.

Thanks, Dan.
This is very odd behaviour, can you ensure you are:


running the latest version of apachesolr (3.6.1)
running the latest version of the apachesolr module (7.x-1.1) OR search_api module (7.x-1.3)
are running the latest schema.xml and solrconfig.xml (hopefully the 3.x version)


Also, try dropping and re-creating the entire index, this normally addresses more problems.
