You should not use TextField.TYPE_STORED to index your docType field: that field type runs the analyzer. I'm not sure that matters in your case, but that's deadly in general. Use StringField instead (it indexes the provided text as a single token).
Likewise for color, size fields. Try running your parentQuery as a search itself and confirm you see totalHits=2? This will tell you if something is wrong in how you indexed the docType field, or created the parent query/filter. Also try running your childQuery separately and confirm you get non-zero totalHits. Hmm, this code never calls indexsearcher.search on the query?
