Assuming that the visit is actually related to Internet monitoring, then the monitoring algorithm is certainly not 'everybody who searches X AND Y AND NOT Z,' but rather some calculated terrorism score. Actually I think it is entirely possible, that whoever does this has no actual idea how the score is calculated and the machine learning algorithm did just pick them because of a random similarity to the search profile.
