我有以下映射字段定义：使用自动完成与弹性搜索电子邮件不起作用
"my_field": {
"properties": {
"address": {
"type": "string",
"analyzer": "email",
"search_analyzer": "whitespace"
}
}
}
我的电子邮件分析是这样的：
{
"analysis": {
"filter": {
"email_filter": {
"type": "edge_ngram",
"min_gram": "3",
"max_gram": "255"
}
},
"analyzer": {
"email": {
"type": "custom",
"filter": [
"lowercase",
"email_filter",
"unique"
],
"tokenizer": "uax_url_email"
}
}
}
}
当我尝试搜索对于电子邮件ID，如[email protected]
搜索像tes，test.xy等术语不起作用。但是，如果我搜索 test.xyz或[email protected]，它工作正常。我尝试使用我的电子邮件过滤器分析令牌，并且如预期的那样正常工作
Ex。击中http://localhost:9200/my_index/_analyze?analyzer=email&[email protected]
我得到：
{
"tokens": [{
"token": "tes",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "test",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "test.",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "test.x",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "test.xy",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "test.xyz",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}, {
"token": "[email protected]",
"start_offset": 0,
"end_offset": 20,
"type": "word",
"position": 0
}]
}
所以我知道在断词的作品。但是在搜索时，它无法搜索部分字符串。
例如，寻找http://localhost:9200/my_index/my_field/_search?q=test，结果显示没有命中。我的指数

有搜索“search_analyzer”：“whitespace”分析器。删除，并做映射 – Backtrack
@Backtrack我相信这是正确的。检查http://stackoverflow.com/a/15932838/1465701。除非我在这里错过了一些东西，否则我认为这应该是正确的行为。 – nerandell
你的贴图存在拼写错误，'analyser'应该读'analytics' – Val
