我的调试查询结果

本地主机：8080 / solr的/ CORE0 /选择技能+：（+（+ “数据+仓库” +）+）^ 10.0）+＆安培; debugQuery =上

40.0 = (MATCH) sum of:
  40.0 = (MATCH) weight(skills:"data warehouse" in 0), product of:

   20.0 = queryWeight(skills:"data warehouse"), product of:
     2.0 = idf(skills: data=6 warehouse=1)
     10.0 = queryNorm

   2.0 = fieldWeight(skills:"data warehouse" in 0), product of:
     1.0 = tf(phraseFreq=2.0)
     2.0 = idf(skills: data=6 warehouse=1)
     1.0 = fieldNorm(field=skills, doc=0)

如何解决我的问题请指导我。
