Instead of intersect you could use grepl(pattern1,x) &
grepl(pattern2,x). Use which() on the result if you must have
integers, but the logicals that grepl() produces are often easier to
use as subscripts.

A version of Eric's answer is to use grepl(), which returns a logical vector:
mydata[grepl("ConfoMap", mydata) & grepl("GuineaPigs", mydata)]
with the OR analogue:
mydata[grepl("ConfoMap", mydata) | grepl("GuineaPigs", mydata)]

Thank you Bert for the pointer.
So I guess the solution is:

This is not the case here, but what if "GuineaPigs" comes before
