with Joomla 2.5.20 and Seblod 3.3.4 I built a list page that provides a checkbox field of filters, that create a url like
In the database I can verify that there are articles saved with comma-separated values from "01" to "25" in my column "features" (type varchar(255) ) in the content table. When I set the filter to select one value, the filter works fine and lists the articles. Whenever I select more than one value, I get "no search result".
I have no clue where to look for the error and would appreciate some help. Thank you.
