Hi Thorsten,

I need to implement some ContentFiltering widgets for a lenya
publication. The widgets are basically selects over certain MetaData
fields on specific resource types.
Our publication is focused on events of a certain region. You can add
events to certain categories and later on edit their content. This
events use meta data that allows filtering like place, start date, end
date, etc.
One specific widget is e.g. cities. The containing options are all
cities of the different events (the duplicates removed). Clicking on the
filter will result in a listing of all events for that city.
What is the preferred method in lenya to get all documents of a certain
resource type?
I guess the most performant way is to use Lucene. The query would be:
{http://apache.org/lenya/metadata/document/1.0}resourceType:foobar
Some more hints:
* Special characters in the query have to be escaped. There's more info
in the query parser syntax docs of Lucene.
* You find an example in the tagcloud module in the contributions area.
This is basically the same task: Find all documents with a particular
meta data value.
* Of course queries can be combined:
+{…}resourceType:foo +{…}city:Sevilla
