0.15uF is far from the largest ceramic cap on the market, yet the slider is limited to 0.15uF. Is this a limitation of the data you are pulling in, or a limitation of the search feature?
Hrm, this is odd. I'll check that out. For now, if you type in the limit to something higher it does show that there are other parts: http://parts.io/search/Class-Capacitors/Category-Ceramic%20Capacitors?Capacitance=0.00001-33
