Yabancı anahtardaki NULL değeri ile Solr Apache yapılandırması INNER JOIN

Question

DB'mden sorgu verilerine izin vermek için Solr'ı yapılandırmaya çalışıyorum. Yapılandırdıktan sonra, başka bir tabloya yabancı bir anahtar olan yeni bir alan ekledim.

Eski kayıtlarda bu alan NULL var.

Şema DB

Tablo: id, type_material (yabancı anahtar), (diğerleri alanları göstermek gerekmez)

---

Tablo:

alanlar sunmaktadır malzemeler

Alanlar: kimlik, ad

Solr yapılandırma

arama sorgu başlangıç, tüm dönmek öyle sunuyor type_material'in alanı NULL'a eşit değil.

Ayrıca bunları tekrar denemek istiyorum.

Answer 1

Sadece Sorunuzun anladığını sanmıyorum bir filtre sorgu &fq=type_material:NULL
