if you have an "eventX" (like event1 and event34) it is custom in your implementation. please ask the person who implemented your adobe analytics or have a look which data is collected when you perform some "searches" on your website.
While I fully support the recommendation from ursboller, I would presume that event1 may stand for total number of searches while event34 could be a serialised event by visit to get some uniqueness on search count.
