如何在Solr中使用配置API添加具有多个字典的suggester组件？

根据，使用config API添加带有1个字典的suggester组件是通过以下请求完成的：

{
    "add-searchcomponent": {
        "name": "suggest",
        "class": "solr.SuggestComponent",
        "suggester": {
            "name": "suggest",
            "lookupImpl": "AnalyzingInfixLookupFactory",
            "dictionaryImpl": "DocumentDictionaryFactory",
            "field": "_suggestField_",
            "suggestAnalyzerFieldType": "suggest_text"
        }
    }
}

但是，指南中没有记录对多个词典执行相同操作

<searchComponent name="suggest" class="solr.SuggestComponent">
    <lst name="suggester">
        <str name="name">mySuggester</str>
        <str name="lookupImpl">FuzzyLookupFactory</str>
        <str name="dictionaryImpl">DocumentDictionaryFactory</str>
        <str name="field">cat</str>
        <str name="weightField">price</str>
        <str name="suggestAnalyzerFieldType">string</str>
    </lst>
    <lst name="suggester">
        <str name="name">altSuggester</str>
        <str name="dictionaryImpl">DocumentExpressionDictionaryFactory</str>
        <str name="lookupImpl">FuzzyLookupFactory</str>
        <str name="field">product_name</str>
        <str name="weightExpression">((price * 2) + ln(popularity))</str>
        <str name="sortField">weight</str>
        <str name="sortField">price</str>
        <str name="storeDir">suggest_fuzzy_doc_expr_dict</str>
        <str name="suggestAnalyzerFieldType">text_en</str>
    </lst>
</searchComponent>

事实证明，Solr config API可以接受具有重复键的JSON。我们可以将上面的suggester XML配置转换为下面的配置API请求

正确的方法是将

suggester

设置为数组

{
    "add-searchcomponent": {
        "name": "suggest",
        "class": "solr.SuggestComponent",
        "suggester": [
            {
                "name": "mySuggester",
                "lookupImpl": "FuzzyLookupFactory",
                "dictionaryImpl": "DocumentDictionaryFactory",
                "field": "cat",
                "weightField": "price",
                "suggestAnalyzerFieldType": "string"
            },
            {
                "name": "altSuggester",
                "lookupImpl": "FuzzyLookupFactory",
                "dictionaryImpl": "DocumentDictionaryFactory",
                "field": "product_name",
                "weightExpression": "((price * 2)) + ln(popularity)",
                "sortField": "price",
                "storeDir": "suggest_fuzzy_doc_expr_dict",
                "suggestAnalyzerFieldType": "text_en"
            }
        ]
    }
}

当您查询ConfigAPI时，您将看到请求和保存的配置是相同的

感谢@MatsLindh为我们提供了解决这个问题的方法

您是否检查了在XML文件中初始配置建议程序时ConfigAPI返回的内容？嗨@MatsLindh，我已经更新了这个问题以包含建议配置。顺便说一句，我还使用了配置API来配置我的建议组件。我的想法是，如果您最初将其配置为XML，然后使用配置API检索该配置，它可以为您提供有关如何（如果）支持它的提示-也许您可以给

或

键的列表。@MatsLindh，我试着做一个简单但违反直觉的请求，结果成功了。事实证明，Solr可以接受具有重复密钥的属性的JSON（即

suggester

）。我会把它贴出来作为将来的参考答案。无论如何，非常感谢你的帮助！
