Search is not including all Constructs/Rems

I sometimes got the creeping suspicion, that not all the Rems of my Knowledge Base get searched. Below you will find a picture showing exactly this. The Construct “Matheamtical Proficincy” (which I created several days ago) could not be find with the include-search (and normal search). Is this a well known bug and what can I do to solve it?

Thanks for the help!
