When I am searching it finds only the beginning of words. This is contrary to what I am used to. And it is not good for a Norwegian, because we tend to put together words into one.
Let me create an example:
In English you say chocolate muffins, but in Norway we make it into one word: sjokolademuffins. That means that if I want to find all occurrences of muffins I will not find sjokolademuffins or bananmuffins.
I often experience this as a limitation. I end up with browsing all the headers in a project to find what I am looking for.
To improve the search function would make a great app even better.
