Searching Markush structures in Marpat vs. MMS

Hello everyone -

I think I asked this question a while ago, and had lots of answers (which
have been lost during a company move) saying I need to search both. Now I
need more specific answers.

I am still somewhat confused about -
        What's in Questel's MMS file and how I can search it using structure
drawings?
        What's Markush DARC?
        What's in Derwent's Compound Registry (and how can I search it and
do I need to subscribe to Derwent to do so)?
        What's the overlap between CAS Registry and Derwent's Registry?
        What's the overlap between Marpat and MMS and what would I miss by
searching in only one of them?
        What's the cost of a search in each one ( Is a search in MMS less?
And if so, is it because it doesn't cover as much?)

As you can see, I need your expert help in sorting all this out.
