1、在apache-tomcat-7.0.42\solr\db\conf下面的solrconfig.xml文件配置一上內容。
2、<str name="queryAnalyzerFieldType">string</str> 爲搜索詞的字段類型， <str name="field">userName</str> 在schema.xml配置的搜索字段名稱，要和schema.xml
裏面的對應不能有錯。
java代碼：
public List<String> suggest(String word) throws Exception {
List<String> wordList = new ArrayList<String>();
SolrClient client = getSolrClient();
SolrQuery query = new SolrQuery("userName:" + word);
query.set("qt", "/suggest");// 請求到suggest中
QueryResponse rsp = client.query(query);
SpellCheckResponse re = rsp.getSpellCheckResponse();// 獲取拼寫檢查的結果集
if (re != null) {
for (Suggestion s : re.getSuggestions()) {
List<String> list = s.getAlternatives();// 獲取所有 的檢索詞
for (String spellWord : list) {
wordList.add(spellWord);
}
}
}
return wordList;
}
