Solr排序问题

我在所有索引字段上得到这个奇怪的错误消息can not sort on multivalued field: fieldname。这是来自solr

的完整错误信息

</head><body><h1>HTTP Status 400 - can not sort on multivalued field: price</h1><hr/><p><b>type</b> Status report</p><p><b>message</b>can not sort on multivalued field: price</p><p><b>description</b>The request sent by the client was syntactically incorrect (can not sort on multivalued field: price).</p><hr/><h3>GlassFish Server Open Source Edition 3.1</h3></body></html>

我确定我的索引字段没有multiValued=true设置在

 <field name="price" type="float" indexed="true" stored="true" multivalued="false" />

以确保我已经添加了multiValued=false，但我仍然得到相同的错误。

这是发送给solr的URL请求

http://localhost:8080/apache-solr-3.1.0/select?wt=ruby&q=flat&fl=_id&sort=price+asc&limit=5&offset=0

和相关的rsolr调用

res = solr.get 'select', :params => {
              :q =>'flat',
              :fl => "_id",
              :sort=>'price asc',
              'limit' => 5,
              'offset' => 0
          }

如果我从请求中删除排序，它就会正常工作。

谁能帮我一下……

PS:我确实只有一个多值字段在文档中，但它不用于排序

更新2:

根据@Mateg的建议，我从模式页面获得了字段详细信息。见下文

Field: price
Field Type: FLOAT
Properties: Indexed, Tokenized, Stored, Multivalued, Omit Norms
Schema: Indexed, Tokenized, Stored, Multivalued, Omit Norms
Index: Indexed, Tokenized, Stored, Omit Norms
Index Analyzer: org.apache.solr.analysis.TokenizerChain DETAILS
Query Analyzer: org.apache.solr.analysis.TokenizerChain DETAILS

表示价格字段为tokenized和multivalued。有趣的是，不仅这个字段是多值的，其他字段也都是多值的

真是一天啊，经过长时间的努力，我终于找到了问题所在。谢谢大家

首先，我不知道设置version number in schema file。根据文档，从1.1

   1.0: multiValued attribute did not exist, all fields are multiValued by nature
   1.1: multiValued attribute introduced, false by default

但是我使用的是1.0版本的旧模式文件。因此，所有字段默认设置为multivalue。

每次我升级solr，我只是复制粘贴旧的模式文件。

现在它可以正常工作后，将其更改为当前版本1.4。

  <schema name="ItemSearch" version="1.4">
