【问题描述】：
我写了一个 lucene 搜索。一切都很好，但搜索返回每篇期刊文章的所有版本。如何对此搜索进行任何限制，使其仅返回期刊文章的最新版本？
这是一段搜索代码：
ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY);
HttpServletRequest httpServletRequest = PortalUtil.getOriginalServletRequest(PortalUtil.getHttpServletRequest(actionRequest));
SearchContext searchContext = SearchContextFactory.getInstance(httpServletRequest);
BooleanQuery fullQuery = BooleanQueryFactoryUtil.create(searchContext);
BooleanQuery searchQuery = BooleanQueryFactoryUtil.create(searchContext);
searchQuery.addRequiredTerm(Field.TITLE, actionRequest.getParameter("searchText"));
if (actionRequest.getParameter("searchType").equals("content")) {
searchQuery.addRequiredTerm(Field.TYPE, "general");
searchQuery.addRequiredTerm("ddmStructureKey", "");
}
.
.
.
fullQuery.add(searchQuery, BooleanClauseOccur.MUST);
searchContext.setStart(QueryUtil.ALL_POS);
searchContext.setEnd(QueryUtil.ALL_POS);
searchContext.setAttribute("paginationType", "none");
Hits hits = SearchEngineUtil.search(searchContext, fullQuery);
List<Document> docs = hits.toList();
当我使用 portlet 3（搜索 portlet）搜索单词“datumu”时，我尝试获取搜索日志，这就是我得到的：
搜索查询 +(+(companyId:10154) +((+(entryClassName:com.liferay.portal.model.User) +(status:0)) (+(entryClassName:com.liferay.portlet.bookmarks. model.BookmarksEntry) +(status:0)) (+(entryClassName:com.liferay.portlet.bookmarks.model.BookmarksFolder) +(status:0)) (+(entryClassName:com.liferay.portlet.blogs.model.

那么是哪个子句造成了限制，所以这次搜索只返回期刊文章的最新版本？

我试图重现这个错误，但它比我想象的要复杂。如果我有时间我明天会再试一次。尝试将 DEBUG 级别的
com.liferay.portal.kernel.search.SearchEngineUtil添加到服务器管理 -> 日志级别。它将打印由SearchEngineUtil执行的每个 Lucene 查询。
