I found an error when I try to use the search box with some keys like : "shared memory" (without quotes). In this case the server always return an "Internal Server Error". If you use this two words alone, the server returns a correct list.
I think that the error is produced when the join of the results contains data from the both words, because if I use some other words without data, the internal error server not appears.... although the result is not correct, because nothing is returned when I use the words : "shared papas" (without quotes).
Best regards, Toni.
