Solr查询具有字段的项目：值或根本没有字段值

Question

I'm trying to query Solr for entries that either have a certain value in a field OR no value for the field. The negated field value works when used by itself but causes the query to return no results when combined with anything else. Below is a response with debugQuery enabled. The config file I use can be found here .

Any help would be appreciated.

Finally phrased the question well enough to find an answer through Google.

OR NOT queries can be written as, using my case as an example:

im_cck_field_affected_plants:20 OR (*:* -im_cck_field_affected_plants:[* TO *])
