I need to store links with large descriptions.

Importing data from the old Links2 db some records could not been imported due the error:

'server has gone away'

so I came to the mysql manual and I found the solution:
start the mysql server...
tryed again and... wow! everything seems to be imported fine.
but... after few tries I wondered that in every search links returns:


with no records visualized!!!

for some reason I cannot understand links refuses to show records.
