Question

我有一个如下查询： http://localhost:8984/solr/UT990001/select?defType=edismax&q=Red+Blue+%2BBlack+-White&qf=cfs_U3RyaW5nQ0Y_3

我的期望是，仅当字段cfs_U3RyaW5nQ0Y_3包含“ Black”而不包含White时，查询才会返回。如果存在红色和蓝色值，则它们在搜索结果中的位置会更高。

这不再适用于我的Solr 7配置。我有2个设置（Solr 4和Solr 7），每个都有相同的数据。当我在Solr 4中运行上述查询时，它可以按预期运行，但是在Solr 7中，返回零结果。

这是我为数据准备的种子的一个概念，值= cfs_U3RyaW5nQ0Y_3的值

Doc1 =红色
Doc2 =红色
Doc3 =黑色
Doc4 =黑色
Doc5 =白色
Doc6 =蓝色
Doc7 =红色黑色白色蓝色
Doc8 =背面和白色

结果：

Solr4：2次匹配，Doc3和Doc4
Solr7：0次点击

任何对从何处开始寻找见解的赞赏。

我们为字段加别名（用户不是搜索cfs_U3RyaW5nQ0Y_3，而是搜索color（为了简化起见，我将搜索的URL简化了）

字段cfs_U3RyaW5nQ0Y_3的类型定义为：

<fieldType name="text_auto" class="solr.TextField" positionIncrementGap="100">
    <analyzer>
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>
        <filter class="solr.WordDelimiterFilterFactory" generateWordParts="1" generateNumberParts="1" catenateWords="1" catenateNumbers="1" catenateAll="0" splitOnCaseChange="1" preserveOriginal="1" />
        <filter class="solr.LowerCaseFilterFactory"/>
    </analyzer>
</fieldType>

从solr 4升级到solr 7后，查询不再起作用（edismax中的“应该发生”还是“必须发生”）
