Set variable limit for number of hosts a search can retrieve

[TheDr1ver]

Right now the number of hosts retrieved using a search string is limited by the amount that can come back in a single API call (I think 100 is the max). 100 is still probably the max we'd want, but we should be able to limit this to something much smaller/more manageable if desired as well in order to make sure it doesn't cause our queries and the event to spiral out of control.
