建议不使用比较器按频率排序Freq =freq(不工作)

我已经在Solr中创建了2个节点,有2个碎片。我正在使用拼写纠正技术。我想排序**********查询(abple)建议,基于频率默认,它是排序*基于分数(Levenshtein距离)。
我在solrconfig.xmlsolr.SpellCheckComponent中添加了<str name="comparatorClass">freq</str>。但是,它仍然工作。

当前建议按得分排序(不要求):

"suggestion":[{
            "word":"apple",
            "freq":23},
          {
            "word":"ample",
            "freq":5},
          {
            "word":"abele",
            "freq":3},
          {
            "word":"able",
            "freq":176}}]

要求建议按频率排序(必需):

"suggestion":[{
            "word":"able",
            "freq":176}},
          {
            "word":"apple",
            "freq":23},
          {
            "word":"ample",
            "freq":5},
          {
            "word":"abele",
            "freq":3}}]

配置文件:

架构.xml:

我也遇到过类似的问题,但我做出了你提到的改变:

<str name="comparatorClass">freq</str>

您可能尚未重新启动solr示例。请先尝试重新启动。

请在将此参数添加到搜索处理程序后尝试:
<str name="spellcheck.onlyMorePopular">true</str>
