Description

ArabicAnalyzer lowercases text in case you have some non-Arabic text around.
It also allows you to set a custom stopword list (you might augment the Arabic list with some English ones, for example).

In this case its helpful for these non-Arabic stopwords, to lowercase before stopfilter.
