使用Elastic Search检索标签内容和带连字符的单词

您可以为特殊字符创建令牌生成器，请参见以下示例

{    "settings" : {        "index" : { "number_of_shards" : 1, "number_of_replicas" : 1        },          "analysis" : { "filter" : {     "custom_filter" : {         "type" : "word_delimiter",         "type_table": ["> => ALPHA", "< => ALPHA"]     }    }, "analyzer" : {     "custom_analyzer" : {         "type" : "custom",         "tokenizer" : "whitespace",         "filter" : ["lowercase", "custom_filter"]     } }        }    },    "mappings" : {        "my_type" : { "properties" : {     "msg" : {         "type" : "string",         "analyzer" : "custom_analyzer"     } }        }    }}

< >作为ALPHA字符，导致基础的word_delimiter将它们视为字母字符。
