<str name="buildOnStartup">false</str>
<str name="buildOnCommit">true</str>
</lst>
</searchComponent>- 設定AnalyzingLookupFactory和AnalyzingInfixLookupFactory兩種查詢演算法。首先通過AnalyzingLookupFactory先分析傳入文字並將分析後的表單新增到加權FST的查詢，然後在查詢時執行相同的操作，若查詢不夠你需求的數量。再通過AnalyzingInfixLookupFactory字首分析。
- 例如 AnalyzingInfixLookupFactory "aaa bbb ccc",可通過bbb,或者ccc搜尋到，而 AnalyzingLookupFactory必須是先從a開始匹配才能出結果。
- AnalyzingInfixLookupFactory可通過標籤
false 關閉高亮提示。 true 可通過此標籤設定軟提交時才進行文字構建。注意此種需求需要在提交文字不頻繁的場景設定。設定軟提交時間
配置在自己core下的conf資料夾中的solrconfig.xml檔案
vim solrconfig.xml <autoSoftCommit>
<maxTime>${solr.autoSoftCommit.maxTime:-1}</maxTime>
</autoSoftCommit>
將maxTime可以設定成你需要的時間，單位是毫秒ms.
- 也可以在solr啟動的時候通過命令設定軟提交：
bin/solr start -force -Dsolr.autoSoftCommit.maxTime=10000設定了軟提交時間後，當有新的文件提交時，會達到設定的軟提交時間才真正提交。
關閉停用詞過濾器
在建立索引的時候，fileType定義的欄位可不加入停用詞過濾器，因為我們要檢索的詞很短，加入會影響檢索結果。
<filter class="solr.StopFilterFactory" ignoreCase="true" words="stopwords.txt" />Java伺服器呼叫suggest介面時，禁用suggest.build=true
加入suggest.build=true這個條件，每輸入一個字元檢索的時候都會去重新構建suggest索引，檢索效率大大減低。通過上面的軟提交方式達到近實時檢索。
