mysql fulltext search and special chars

Question

hi guys,

I'm using php + mysql with a full text index. I have the following contents in the field I want to search:

"Hello: it's a test!"

"Hello i am also a test!"

When I search for "hello:", it finds both rows. But It should only find the first row - at least until I search for "hello%". The colon seems not tot be treated as a "normal" charakter.
