SOLR 8.1.1 EdgeNGramFilterFactory解析查询

Question

我有一个 SOLR 4.10.2 核心，我正在升级到 8.1.1。

我使用 default_config 设置手动创建了一个 8.1.1 核心，然后将设置引入 8.1.1 模式。

我已经调整了schema.xml和solrconfig.xml，并且我在8.1.1中有核心可查询。

我有一个名为公司的字段：

<field name="Company" type="string" indexed="true" stored="true"/>
<field name="IDX_Company" type="text_general" indexed="true" stored="false" multiValued="true" />
<copyField source="Company" dest="IDX_Company"/>

在4.10.2的时候我运行查询：

IDX_Company:蓝色

打开 debugQuery，我看到查询被解析成多个部分（正确地）

"debug": {
    "rawquerystring": "IDX_Company:blue",
    "querystring": "IDX_Company:blue",
    "parsedquery": "(IDX_Company:b IDX_Company:bl IDX_Company:blu IDX_Company:blue)/no_coord",

...

当我针对 8.1.1 运行启用 debugQuery 时，我得到以下信息：

"debug":{
    "rawquerystring":"IDX_Company:blue",
    "querystring":"IDX_Company:blue",
    "parsedquery":"IDX_Company:blue",

...

它似乎没有应用 EdgeNGramFilterFactory - 根据文档，我对 EdgeNGramFilterFactory 配置所做的唯一更改是删除 "side" 属性。此外，根据文档，我将 SynonymFilterFactory 替换为 SynonmGraphFilterFactory，并添加了 FlattenGraphFilterFactory。

我尝试删除 FlattenGraphFilterFactory，我已经清除并重新填充核心（重新索引），我已经停止并启动 SOLR 8.1.1，没有区别。

这是我在schema.xml

中使用的text_general的定义

<fieldType name="text_general" class="solr.TextField" positionIncrementGap="100" multiValued="true">

        <tokenizer class="solr.StandardTokenizerFactory"/>

        <filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />
        <!-- RDH SynonymFilterFactory has been deprecated, replace with SynonymGraphFilterFactory -->
        <filter class="solr.SynonymGraphFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/> 
        <!-- RDH https://lucene.apache.org/solr/guide/8_1/filter-descriptions.html
            Flatten Graph Filter

    </fieldType>

Answer 1

虽然我通过清除数据并将数据发布到核心中来重新加载信息，但我忽略了转到核心管理页面，选择核心，然后单击重新加载按钮。

现在查询已按预期解析。
