示例1: optimizePreFetchDocs
import org.apache.solr.response.SolrQueryResponse; //导入方法依赖的package包/类
/**
* Pre-fetch documents into the index searcher's document cache.
*
* This is an entirely optional step which you might want to perform for
* the following reasons:
*
* <ul>
* <li>Locates the document-retrieval costs in one spot, which helps
* detailed performance measurement</li>
*
* <li>Determines a priori what fields will be needed to be fetched by
* various subtasks, like response writing and highlighting. This
* minimizes the chance that many needed fields will be loaded lazily.
* (it is more efficient to load all the field we require normally).</li>
* </ul>
*
* If lazy field loading is disabled, this method does nothing.
