THIS ! I feel many times business put the "business-complexities" onto the client, in this case the search-unit and although the CTO explained why (I gloss over it) as a customer , I don't need to understand what makes it difficult in your business nor do I want to know all your internal jargon and limitations. I the customer understand searches and searches per month. Don't make me think !

Like going to a restaurant: I don't want to know the whole nine yards story as to why you don't have lasagne today since one of the guys didn't show up for work and he was supposed to make the sauce and another guy was over his government allowed working hours. All this might be true and adequately explained why there is no lasagne, but now I need to also understand about employees, government working hours and and and. Just give me lasagne or not :) It's almost always a red-herring if you need to "explain" your pricing or use internal-company-jargon in your pricing-pages.
