我希望能够处理过度具体的搜索字词。因此，如果用户搜索＆＃34;征税＆＃34;我希望能够包含 tax 的结果，但前提是它包含在 title 字段中。下面是我的Elasticsearch配置。我使用的是1.5版本。

搜索查询
{
"from":0,
"size":"10",
"query":{
"bool":{
"must":[
{
"multi_match":{
"query":"taxation",
"fields":[
"body:value^13.0",
"content_page_tab_data^13.0",
"field_body:value^13.0",
"field_tabs_page_body:value^13.0",
"title^21.0"
]
}
}
],
"should":[
{
"query_string":{
"query":"(taxation)",
"fields":[
"body:value^13.0",
"content_page_tab_data^13.0",
"field_body:value^13.0",
"field_tabs_page_body:value^13.0",
"title^21.0"
]
}
},
{
"fuzzy_like_this" : {
"fields" : ["title"],
"like_text" : "taxation",
"fuzziness": "AUTO"
}
}
]
}
}
}
以上查询不会返回标题包含＆＃34; tax＆＃34;但是＆＃34;税收＆＃34;只要。我也不想包含不相关的结果，如＆＃34;关系＆＃34;或＆＃34;行动＆＃34;。
