Is there a decent dictionary that includes 搭配, or words that the searched word cannot be used with? I use Pleco, but one of my largest complaints with it is there is really no baseline for how the words are used, other than the few example sentences that are provided. Using Pleco, there is no good way to determine when to use 维持、维护、保持、持续、etc, or any of the subtle differences between 实习、实践、进行、实行, etc.
