This should work:

  $ export NOTMUCH_DEBUG_QUERY=1
  $ notmuch count -- from:suvayu attachment:*.pdf
  Query string is:
  from:suvayu attachment:*.pdf
  Exclude query is:
  Xapian::Query()
  Final query is:
  Xapian::Query((Tmail AND ZXFROMsuvayu:(pos=1) AND Zattach:(pos=2) AND Zpdf:(pos=3)))
  217
  $ notmuch count -- from:suvayu attachment:pdf
  Query string is:
  from:suvayu attachment:pdf
  Exclude query is:
  Xapian::Query()
  Final query is:
  Xapian::Query((Tmail AND ZXFROMsuvayu:(pos=1) AND ZXATTACHMENTpdf:(pos=2)))
  151

I guess to answer the OP's question, the globbed form simply does a text
search of attach and pdf.  The keyword is not recognised at all.
