SOLR查询以检查是否设置了字段

Question

so I added a new field called 'theField' to my documents. Some of them managed to have the fields set correctly others don't

How do I go about making a SOLR query to only select documents whose 'theField' field is set properly?

Answer 1

You can use a Range Query with both ends open. like:

theField:[* TO *]
