I have a large solr index, and I have noticed some fields are not updated correctly (the index is dynamic).
This has resulted in some fields having an empty "id" field.
I have tried these queries, but they didn't work:
id:''
id:NULL
id:null
id:""
id:
id:['' TO *]
Is there a way to query empty fields?
Thanks
Try this:
?q=-id:["" TO *]
