It works as expected. The append, well, appends the parameter and because each collection has a unique value, specifying two filters on different collections will always yield zero results.
This, of course, won't work for values that are shared between collections. -----Original message----- From: Yonik Seeley <yo...@lucidimagination.com> Sent: Wed 08-09-2010 19:38 To: solr-user@lucene.apache.org; Subject: Re: Re: Invariants on a specific fq value 2010 at 1:32 PM, Markus Jelsma <markus.jel...@buyways.nl> wrote: > Interesting!

Here's a comment from the example solrconfig.xml: <!-- In addition to defaults, "appends" params can be specified to identify values which should be appended to the list of multi-val params from the query (or the existing "defaults"). In this example, the param "fq=instock:true" will be appended to any query time fq params the user may specify, as a mechanism for partitioning the index, independent of any user selected filtering that may also be desired (perhaps as a result of faceted searching). NOTE: there is *absolutely* nothing a client can do to prevent these "appends" values from being used, so don't use this mechanism unless you are sure you always want it. --> -Yonik http://lucenerevolution.org Lucene/Solr Conference, Boston Oct 7-8
