I presume that you mean a missing field, not a blank field. You can do
this by using TermRangeQuery and passing null for term values. A null
value means that it's an open end ([A To *] or [* TO Z]), two null
values means it will match anything ([* TO *]). The main difference
compared to MatchAl
Give blank entries some value that will never appear otherwise and search
on it, that's the easiest solution

I would be interested in hearing a good solution for this as well. Currently,
I am handling missing values with the word: "(blank)".
Not sure if there is a capability to pull all the matching documents that don't
have a particular field.
