如何在solr中实现自动提示？

Question

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，它应该从这个字段中检索单词作为建议如何做？

Answer 1

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">
  <title>jQuery UI Autocomplete - Default functionality</title>
  <link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">

  <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<style>
  em{
    width: auto;
    height: auto;
    background-color: yellow;
    overflow:auto;
  }


.ui-menu .ui-menu-item {

    float: left;
    clear: left;
}
/*
.ui-menu .ui-menu-item {
/*  margin:0; */
    padding: 0;
    zoom: 1;
    float: left;
    clear: left;
    width: 100%;

*/

 </style>

  <script>
  $(function() {
