Do you mean something like entering ra and game in the search box?
Here in BGG, yes. He means that.
The problem arises when you search for Ra in any on-line store, other board gaming sites, etc. Most search algorithms just search for the string "ra" anywhere in the title, so the long list can be annoying at times.
I haven't found a generic solution to this, and I doubt it even exists. All search algorithms are a bit different...
