Sunspot Solr像Rails一样搜索活动记录'LIKE'搜索

Question

嗨我一直在我的应用程序中使用普通的rails活动记录LIKE搜索,我开始使用太阳黑子solr搜索.我希望它尽可能接近轨道LIKE搜索.

---

wine.rb

#sunspot stuff
  searchable :auto_index => true, :auto_remove => true do
  text :name
end
#sunspot stuff

---

的solr/CONF/schema.xml中

<fieldType name="text" class="solr.TextField" omitNorms="false">
  <analyzer>
    <tokenizer class="solr.StandardTokenizerFactory"/>
    <filter class="solr.StandardFilterFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
</fieldType>

---

application_controller.rb

search_string = "will input some values here"
query = "%" + search_string + "%"

solr_search = Wine.search do
  fulltext search_string
end
@solr_search_results = solr_search.results.sort_by{|e| e[:id]}

@rails_search_results = Wine.find(:all, :conditions => ['wines.name LIKE ?' , query]).sort_by{|e| e[:id]}

好像Solr中没有发现与他们"尊驰"的条目,只找到了确切火柴？我怎样才能解决这个问题？

3478 Roodeberg White
3594 Roodeberg White
3604 Roodeberg Red

同样的事情发生在这里,solr没有找到'Roodeberg'当search_string ='rood'时,它只找到完全匹配

更新

将nGram过滤器添加到schema.xml以进行部分匹配,感谢DanS
但仍未显示所有结果

应用程序/ solr的/ CONF/schema.xml中

<fieldType name="text" class="solr.TextField" omitNorms="false">

    <analyzer type="index">
        <tokenizer class="solr.LowerCaseTokenizerFactory"/>
        <filter class="solr.NGramFilterFactory" minGramSize="3" maxGramSize="15"/>
    </analyzer>

    <analyzer type="query">
        <tokenizer class="solr.LowerCaseTokenizerFactory"/>
    </analyzer>

</fieldType>

它仍然不能完成我想要它做的事情,看看下面的例子

固定的！似乎 Solr 默认情况下只显示 30 个条目，因此它只显示最相关的匹配项，并跳过了我也想要的其他匹配项。
我添加了这个文件

myapp/config/initializers/sunspot_solr.rb

Sunspot.config.pagination.default_per_page = 3000
