+Hi, by default xapian/omega use locate param from blog.setup to set stemmer language when wiki is indexing.
+
+But, when you search, we use omega cgi, and we not set language, so if you indexing in french, but search in english, you have a bad result.
+
+I propose to set a new param omega_stemmer in blog.setup, to fix the same language when we indexing, and searching. And if omega_stemmer is not set, we use LANG env param.
+
+Bellow, you can find the patch.
