We have been using: -myField:*
You would need to us
Hi Jason,
The easiest way would be to set some default value for the field which is
empty, Say EMPTY and search for this string to check out the records having
empty field.

Now my question is how will I search for all the documents with

Field2?
You can search for "-field2:[* TO *] AND *:*" essentially. With
Solr, the *:* isn't needed, but is with pure Lucene to ensure a
positive query also.

You don't as far as I know. One solution that has been suggested is
to always index field2, but with a noop value. This works pretty well
if you choose a value you'd never search for, say xzxzxzxzxzxzxzx.
Then you can search field2 for that special value to get the *empty*
case.

AFAIK there is no strait way of doing that, however you can create
another field (field4) which can indicate if field2 exists.
