我在Lucene 5.0中对字符串字段进行排序时遇到问题.自Lucene 4改变以来你可以选择的方式.下面显示了我的文档索引的一些字段的片段.

    return doc;
}

我想首先考虑相关性,这很好.我遇到的问题是在标题字段上排序不起作用.我创建了一个sortfield,我试图在一系列方法调用之后使用TopFieldCollector.

public BaseSearchCore<Process, ProcessSearchResultScore>.SearchContainer search(String searchQuery, Filter filter, int page, int hitsPerPage) throws IOException, ParseException
    {
    SortField titleSort = new SortField(title, SortField.Type.STRING, true);
    return super.search(searchQuery, filter, page, hitsPerPage, title);
    }

其中:

public SearchContainer search(String searchQuery, Filter filter, int page, int hitsPerPage, SortField... …
