我是 solr 场景的新手，我在 solr 中索引了一个名为“displayName”的字段。现在我想在 solr 中实现自动建议，它应该从该字段检索单词作为建议，如何做到这一点？
最佳答案
在 solrconfig.xml 中更改以下内容
之前
<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">name_s</str>
<str name="weightField">price</str>
<str name="suggestAnalyzerFieldType">text_general</str>
<str name="buildOnStartup">false</str>
</lst>
</searchComponent>
<requestHandler name="/suggest" class="solr.SearchHandler"
startup="lazy" >
<lst name="defaults">
<str name="suggest">true</str>
<str name="suggest.count">10</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>
在 JSP 中尝试以下代码
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
