In Category:Wiktionary-namespace discussion pages on the English Wiktionary, I want to have the inputbox search only in the Wiktionary (Project) namespace, to override user preferences (because I didn't have the Wiktionary namespace selected and saw no results!) and maybe save server resources.
searchfilter=Wiktionary: ... doesn't work, because the filter is placed at the end of the search query (that is, if you enter
blah in the box, you get the query
blah Wiktionary: ...) and then the namespace filter doesn't work. Adding
namespaces=Wiktionary works, but it adds whitespace (a
<br> tag) between the textbox and the button; maybe the extension tries to create checkboxes and fails because there's only one namespace.
Any non-buggy way to choose one namespace to search in?
