and then search for files containing SBD-BS in file name, it does not list 
these two files:

If I shorten the name of the file to less than 41 characters the file shows up in 
the search result...

-------------------- another run start --------------------

swishlin:~/swishtest# mv files/SDB-BS-07-Kaliumsorbat-Granulat-105119.pdf files/SDB-BS-07-Kaliumsorbat-Granulat-1051.pdf

Is this a bug or am I missing some settings / parameters?

Thanks in advance
