我有一个可以直接使用Solr 4.9并具有现成的配置和架构的搜索系统。
在Solr 6.2中，突出显示条目将在结果中返回，但是它们仅包含文档ID，没有突出显示文本。
起初我以为是因为“内容”不在默认(托管)模式中，但是添加它没有任何区别。无论如何，默认模式中有其他字段(作者，主题，标题等)可以返回突出显示的文本，但这些都什么也没有。
突出显示似乎已在默认配置中启用，并且我的查询似乎正常(从管理界面运行时，它也不返回任何HL文本，因此排除了我的代码):
q = mike＆rows = 10＆start = 0＆sort =得分说明，last_modified desc＆wt = json＆fl = content_type，fsb_doctype，author，id，last_modified，主题，标题，得分，url＆hl = true＆hl.fragsize = 250＆hl.fl =内容，作者，主题，title＆hl。 simple.pre =％3Cb％3E＆hl.simple.post =％3C％2Fb％3E＆facet = true＆facet.field = fsb_doctype＆facet.field = fsb_origin＆facet.field = fsb_mission
我所做的唯一架构更改是在构面中添加了3个自定义字段。
这是在Solr 4.9系统上返回的json示例(仅突出显示部分):

这是6.1 json结果的示例(此服务器上的文档集略有不同，但是两种情况下的第一个结果都是相同的:
"highlighting":{"/event_20060718.cfm":{},"/event_20080516.cfm":{},"/event_20140918.cfm":{},"/event_20111011.cfm":{},"/LRO/":{},"/SDODocs/":{},"/event_20060201.cfm":{},"TDL_582 Web&id=353":{},"TDL_582 Web&id=67":{},"TDL_BSR JWST&id=94":{}
因此，我得到的是没有突出显示文本的文档ID列表。
最佳答案
将您的代码更改为如下所示即可:select?q=I+WANT+PIZZA&wt=php&indent=true&fl=id,name&group=true&group.field=content&hl=on&hl.fl=*&hl.encoder=html&hl.fragmenter=regex&hl.regex.slop=100.0&hl.fl=text_*&hl.bs.type=WHOLE&hl.defaultSummary=true&hl.offsetSource=POSTINGS
