全文搜索
执行全文搜索
全文搜索用于在较长的文本中查找单词或短语。您可以在特定的文本字段内搜索,也可以跨所有文本字段进行搜索。
本文提供了最相关的全文搜索功能的良好概述。有关所有全文搜索功能的更多详细信息,请参见参考文档。
本文中的示例使用具有以下字段的模式
字段名称 | 字段类型 |
---|---|
brand |
TEXT |
model |
TEXT |
description |
TEXT |
单个单词
要在所有文本字段中搜索单词(或词干),您可以构建以下简单查询
FT.SEARCH index "word"
您可能希望将搜索限制到特定的文本字段,而不是在所有文本字段中搜索。
FT.SEARCH index "@field: word"
自然语言中非常常见的单词,例如英语中的 the
或 a
,不会被索引,也不会返回搜索结果。您可以在停用词文章中找到更多详细信息。
以下示例搜索描述中包含单词 'kids' 的所有自行车
FT.SEARCH idx:bicycle "@description: kids"

模糊搜索
模糊搜索允许您查找包含与您的搜索词大致匹配的单词的文档。要执行模糊搜索,您需要用一对 %
字符包围搜索词。一对代表(Levenshtein)距离一,两对代表距离二,三对(最大距离)代表距离三。
这是在所有文本字段中搜索距离为一的命令
FT.SEARCH index "%word%"
以下示例查找所有包含与拼写错误的单词 'optamized' 距离为一的单词的文档。您可以看到这匹配了单词 'optimized'。
FT.SEARCH idx:bicycle "%optamized%"
