I'm looking for a CQL query that will return all positions with the below pawn structure for both White and Black
[FEN "8/pp3ppp/4p3/8/3P4/8/PP3PPP/8 w - - 0 1"]

(match ;query for IQP white
(position
:and (
(position Pa2 Pb2 Pd4 Pf2 Pg2 Ph2 pa7 pb7 pe6 pf7 pg7 ph7)
(position
:piececount P[c2-7,e2-7] 0
:piececount p[c2-7,d2-7] 0 )
)
)
)
For black though, I wanted to search for any IQP position, so I used this query:
(match ;query for IQP black
(position
:and (
(position pd5)
(position
:piececount P[a2-7] 1
:piececount P[b2-7] 1
:piececount P[c2-7] 0
:piececount P[d2-7] 0
:piececount P[e2-7] 1
:piececount P[f2-7] 1
:piececount P[g2-7] 1
:piececount P[h2-7] 1
:piececount p[a2-7] 1
:piececount p[b2-7] 1
:piececount p[c2-7] 0
:piececount p[d2-7] 1
:piececount p[e2-7] 0
:piececount p[f2-7] 1
:piececount p[g2-7] 1
:piececount p[h2-7] 1
)

Lame, but at least it works :)
