ElasticSearch

您可以尝试使用映射字符过滤器删除连字符：

CN/elasticsearch/reference/current/analysis-mapping-
charfilter.html

像这样会删除连字符：

{    "index" : {        "analysis" : { "char_filter" : {     "my_mapping" : {         "type" : "mapping",         "mappings" : ["-=>"]     } }, "analyzer" : {     "custom_with_char_filter" : {         "tokenizer" : "standard",         "char_filter" : ["my_mapping"]     } }        }    }}

这是一种钝器，因为它会去除所有的连字符，但应使“ T恤”和“ T恤”匹配
