When I use the search, I cannot find my pack !

The search engine only search for entire word : 'car' will not match 'care' nor 'careful', you can use the star as at the word's endding : 'car*' will match 'care' and 'careful'. The star trick does not work at the beginning of a word.

As another workaround, you can search for your pack in the 'Advanced search', it is always up-to-date but does not allow to search a description or a link (only title, pseudo, adsense ID and number of links)
