Dictionary can't find capitalized words in Norwegian

[crosby88]

Describe the bug
I have a working local wiktionary dump for Norwegian. It has no issue looking up words that are fully lowercase. However, if a word has any capital letters in it then it can't find a definition.

To Reproduce
Steps to reproduce the behavior:

1. Set target language to Norwegian, get a working wiktionary dump (this is a process on its own but whatever)
2. Give it a Norwegian sentence where some words have capital letters
3. Look up capitalized word -> no definitions found
4. Edit word to be all lowercase -> definition found

Expected behavior
Give me a definition without having to make the word lowercase myself

Screenshots
Sentence as is, can't find definition for "Hvorfor"

Now I made it "hvorfor" all is well
