Solr 拼写检查多词

Question

无法找出我配置的 Solr 拼写检查器未提供所需输出的真正原因。在我的索引数据查询中：symphony+mobile 有大约 3.5K+ 文档，拼写检查器检测到它拼写正确。当我在查询中拼错 "symphony" 时：symphony+mobile 它只显示 "mobile" 的结果，拼写检查器检测到此查询拼写正确。我以不同的组合搜索了这个查询。请找到搜索结果统计

查询：交响曲

**ResultFound**: 1190
**SpellChecker**: correctly spelled

查询：手机

**ResultFound**: 2850
**SpellChecker**: correctly spelled

查询: simphony

**ResultFound**: 0
**SpellChecker**: symphony 
**Collation Hits**: 1190

查询: symphony+mobile

**ResultFound**: 3585
**SpellChecker**: correctly spelled

查询: simphony+mobile

**ResultFound**: 2850
**SpellChecker**: correctly spelled

查询：symphony+mbile

**ResultFound**: 1190
**SpellChecker**: correctly spelled

在最后两个查询中，它应该针对拼写错误的单词 "simphony" 和 "mbile"

提出一些建议

请在下面找到我的配置。仅显示拼写检查配置。

已解决 :) 找到了我的问题的真正原因。我将 "maxResultsForSuggest" 设置为 5，这就是它不显示建议的原因，因为查询中的每个词的搜索结果都多于 5
