SOLR选择请求错误 - Java类强制转换异常

标签： java php solr solr4 deep-linking

我在原始码头上运行solr 4.8.1并通过php脚本查询。当我在第一个光标标记上查询按价格和id排序的数据时，如“cursorMark = *”，它会正确返回。但是当用下一个光标标记再次查询时，我得到如下所示的错误。虽然当我使用某种创建日期或价格查询时，查询可以完美地运行。

完整查询如下所示： http://localhost:8983/solr/collection1/select?q=age%3A".$age_q."+AND+gender%3A".$gender_q."+AND+category%3A".$category_q."+AND+type%3A".$type_q."+AND+price%3A".$price_q.$sort_q.$rows.$fl.$cursorMark

相关架构字段为：

<field name="title" type="text_general" indexed="true" stored="true" />
   <field name="description" type="text_general" indexed="true" stored="true"/>
   <field name="retailer" type="text_general" indexed="true" stored="true"/>

   <field name="links" type="string" indexed="true" stored="true" />
   <field name="id" type="string" indexed="true" stored="true" required="true"   
multiValued="false" />

看起来你的演员阵容不正确：

 java.lang.Float cannot be cast to java.lang.Long

我想我在文档中看到一些内容表明您无法在float上进行范围查询，您可以使用sfloat

如果从AND+price%3A*查询参数中删除q会怎样？

  

逐字存储和索引文本值的数字字段类型（因此不支持范围查询，因为字典顺序不等于数字排序）：

<fieldtype name="integer" class="solr.IntField" omitNorms="true"/> 
<fieldtype name="long" class="solr.LongField" omitNorms="true"/> 
<fieldtype name="float" class="solr.FloatField" omitNorms="true"/> 
<fieldtype name="double" class="solr.DoubleField" omitNorms="true"/>
     

数值字段类型，它将值操作为字符串值，该字符串值在其内部形式中不是人类可读的，但字典顺序与数字排序相同，以便范围查询正常工作。 

<fieldtype name="sint" class="solr.SortableIntField" sortMissingLast="true"  omitNorms="true"/> 
<fieldtype name="slong" class="solr.SortableLongField" sortMissingLast="true  " omitNorms="true"/> 
<fieldtype name="sfloat" class="solr.SortableFloatField" sortMissingLast="tr  ue" omitNorms="true"/> 
<fieldtype name="sdouble" class="solr.SortableDoubleField" sortMissingLast="  true" omitNorms="true"/>
