Solr的更好的搜索结果,我已经配置Solr的为我的电子商务应用软件(主要包含图书资料)。搜索结果似乎没有回报我所期望的。与相邻的查询关键词
以下是配置。

time and is mandatory. Optional fractional seconds are allowed: 1995-12-31T23:59:59.999Z
All other components are mandatory. Expressions can also be used to denote
calculations that should be performed relative to "NOW" to determine the
value, ie... NOW/HOUR ... Round to the start of the current hour NOW-1DAY
... Exactly 1 day prior to now NOW/DAY+6MONTHS+3DAYS ... 6 months and 3 days

对于例如,当我搜索2个状态时,它给了我很多随机结果,甚至在标题中甚至没有包含2个状态。
然而,当我搜索的短语“2个国” 2个状态,我得到的相关结果”
我不想限制每一个搜索到的报价,因为用户可以搜索,如“书的作者”如果在搜索短语,因为它不会完全相符的词组,这当然给0结果的某种组合。
我怎样才能imporve我的搜索,这样我可以在最上面列出最相关的结果。
能否请您分享您使用来从Solr的结果整个查询? –
