While I'm happy with the response, I still think the text should make this

There should at least be one example using stopwords not sandwiched between

Our implementation ignores stopwords at query time (i.e. they are handled in
our implementation of matchTokenInfos).  Where S is a stopword and C is a
non-stopwor, we treat:

S+ as a query matching no results.
S* T+ S* as if the query were T* (i.e. strip head and teal stopwords)
T+ S+ T+ as if the query were T+ .+ (for each S) T+

This interpretation allows us to pass the XQFTTS tests.
