示例1: getHit

* Get Hit by Lucene id. Used for tests only
* @param hitId
* @return hit
* @throws IOException

示例2: doPagingSearch
import org.apache.lucene.search.TopScoreDocCollector; //導入方法依賴的package包/類
/**
* This demonstrates a typical paging search scenario, where the search engine presents pages of size n to the user. The user can
* then go to the next page if interested in the next hits.
*
* When the query is executed for the first time, then only enough results are collected to fill 5 result pages. If the user wants
* to page beyond this limit, then the query is executed another time and all hits are collected.
