[ic] mv_raw_searchspec remains undefined

[Craig Carman]

Dear IC Acquaintances,

Where and how do I learn the use of mv_raw_searchspec (SE) since
it seems to be undocumented?

The archives told me nothing useful and the docs literally skip
any definition or example.  A sentence fragment in the archives 
leads me to suspect mv_raw_searchspec would contain all search 
terms . . . but . . .
Must I define it myself?
How do I access the content segments?
Is there some formula used to parse out the search spec variable?
Is this subject an intentional gap in the docs or have I missed
the thought process completely?

All comments are appreciated.  This makes the Nth time the IC 
learning curve has made me feel stupid!

Thanks,
