在完成solr的搭建后（solr搭建可以参考这篇：http://lucien-zzy.iteye.com/blog/2002087）
我们来看看如何实现suggest输入拼音提示中文的功能：
这里我是基于http://lucien-zzy.iteye.com/blog/2002087 这篇来搭建的。
第一步：将这俩jar包放入 F:\winsolr\solr_home\solr\collection1\contrib\extraction\lib 中
jar包见附件
第二步：配置 solrconfig.xml 文件，添加以下内容
<searchComponent name="spellcheck" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">text_spell</str>
<lst name="spellchecker">
<str name="name">default</str>
<!--这里指明需要根据哪个字段的索引为依据进行拼写检查。现配置 名为 name 的字段-->
<str name="field">text</str>
<!--拼写检查索引的目录-->
<str name="spellcheckIndexDir">spellchecker</str>
<!--当commit的时候，对拼写检查索引进行构建。(只有构建后，拼写检查才有效果)-->
<!--当然，也可以选择在optimize的时候，进行构建。那么只需要将"buildOnCommint"换为 "buildOnOptimize"-->
<str name="buildOnCommit">true</str>
<str name="classname">solr.FileBasedSpellChecker</str>
<str name="sourceLocation">spellings.txt</str>
<str name="characterEncoding">UTF-8</str>
<!--
<str name="name">direct</str>
<str name="field">text</str>
<str name="classname">solr.DirectSolrSpellChecker</str>
<str name="distanceMeasure">internal</str>
<float name="accuracy">0.5</float>
<int name="maxEdits">2</int>
<int name="minPrefix">1</int>
<int name="maxInspections">5</int>
<int name="minQueryLength">2</int>
<float name="maxQueryFrequency">0.01</float>
-->
</lst>
</searchComponent>
<requestHandler name="/spell" class="solr.SearchHandler" startup="lazy">
<!--默认参数-->
<lst name="defaults">
<str name="spellcheck.onlyMorePopular">true</str>
<str name="spellcheck.extendedResults">false</str>
<!--配置拼写检查提示结果的个数(可以根据需要适当加大)-->
<str name="spellcheck.count">3</str>
</lst>
<arr name="last-components">
<str>spellcheck</str>
</arr>
<!--
<lst name="defaults">
<str name="spellcheck.dictionary">direct</str>
<str name="spellcheck">on</str>
<str name="spellcheck.collate">true</str>
<str name="spellcheck.collateExtendedResults">true</str>
</lst>
<arr name="last-components">
<str>spellcheck</str>
</arr>
-->
</requestHandler>
<searchComponent name="suggest" class="solr.SpellCheckComponent">
<str name="queryAnalyzerFieldType">string</str>
<lst name="spellchecker">
<str name="name">suggest</str>
<str name="classname">org.apache.solr.spelling.suggest.Suggester</str>
<str name="lookupImpl">org.apache.solr.spelling.suggest.tst.TSTLookup</str>
<str name="field">text</str>
<float name="threshold">0.0001</float>
<str name="spellcheckIndexDir">spellchecker</str>
<str name="comparatorClass">freq</str>
<str name="buildOnOptimize">true</str>
<!--<str name="buildOnCommit">true</str>-->
</lst>
<!--用于输入拼音提示功能-->
<lst name="spellchecker">
<str name="name">pysuggest</str>
<str name="classname">shentong.tsearch.spelling.suggest.Suggester</str>
<str name="lookupImpl">shentong.tsearch.spelling.suggest.py.PYLookup</str>
<str name="field">text</str>
<float name="threshold">0.0001</float>
<str name="pySuggestIndexDir">suggestIndex</str>
<str name="comparatorClass">freq</str>
<str name="buildOnOptimize">true</str>
<!--<str name="buildOnCommit">true</str>-->
</lst>
</searchComponent>
<requestHandler name="/suggest" class="solr.SearchHandler" startup="lazy">
<lst name="defaults">
<str name="spellcheck">true</str>
<str name="spellcheck.dictionary">suggest</str>
<!-- 这个参数告诉solr，当查询的结果数多于设定的count数时，返回点击数更多的那些 -->
<str name="spellcheck.onlyMorePopular">true</str>
<str name="spellcheck.extendedResults">false</str>
<str name="spellcheck.count">10</str>
<str name="spellcheck.collate">true</str>
</lst>
<arr name="components">
<str>suggest</str>
</arr>
</requestHandler>
第三步：增加索引
第四步：结合Ajax 实现suggest（这里只贴出主要的solrj查询代码）
JSONObject json = new JSONObject();
//获取请求的实际URL相对于请求的serlvet的url的路径。
String requesturl = request.getPathInfo();
//检索建议
if(requesturl.indexOf("/suggest") != -1){
String data = request.getParameter("data");
if(!StringUtil.empty(data)){
String url = ConfigUtil.getStringValue("solr_url");
SolrjTool solr = SolrjTool.getinstence();
solr.init(url);
//创建查询对象
SolrQuery query = new SolrQuery();
query.set("q", data); //set查询关键词
query.set("qt", "/suggest"); //set查询类型为 suggest
query.set("spellcheck.count", "10"); //set 查询出的总条数
query.set("spellcheck.dictionary", "pysuggest");
query.set("spellcheck", "on");
query.set("spellcheck.build", "true");
//执行查询
QueryResponse res = solr.execseQuery(query);
SpellCheckResponse spellCheckResponse = res.getSpellCheckResponse();
if (spellCheckResponse != null) {
//获取Suggestion集合
List<Suggestion> suggestionList = spellCheckResponse.getSuggestions();
List<String> suggestedList = new ArrayList<String>();
for (Suggestion suggestion : suggestionList) {
//获取索引库集合
List<String> suggestedWordList = suggestion.getAlternatives();
for (int i = 0; i < suggestedWordList.size(); i++) {
String word = suggestedWordList.get(i);
suggestedList.add(word);
}
}
if(suggestedList.size() >0 ){
json.put("code", "1");
json.put("data", suggestedList);
}else{
//没有结果
json.put("code", "1001");
}
}else{
//没有结果
json.put("code", "1001");
}
}else{
//没有检索项
json.put("code", "1000");
}
out.println(json.toString());
}
第五步：访问页面查询测试，如图：
