测试分析器
编辑测试分析器编辑
analyze API 是一个用于查看分析器生成的词项的宝贵工具。可以在请求中内联指定内置分析器
response = client.indices.analyze(
body: {
analyzer: 'whitespace',
text: 'The quick brown fox.'
}
)
puts response
POST _analyze
{
"analyzer": "whitespace",
"text": "The quick brown fox."
}
API 返回以下响应
{
"tokens": [
{
"token": "The",
"start_offset": 0,
"end_offset": 3,
"type": "word",
"position": 0
},
{
"token": "quick",
"start_offset": 4,
"end_offset": 9,
"type": "word",
"position": 1
},
{
"token": "brown",
"start_offset": 10,
"end_offset": 15,
"type": "word",
"position": 2
},
{
"token": "fox.",
"start_offset": 16,
"end_offset": 20,
"type": "word",
"position": 3
}
]
}
您还可以测试以下各项的组合
- 分词器
- 零个或多个词元过滤器
- 零个或多个字符过滤器
response = client.indices.analyze(
body: {
tokenizer: 'standard',
filter: [
'lowercase',
'asciifolding'
],
text: 'Is this déja vu?'
}
)
puts response
POST _analyze
{
"tokenizer": "standard",
"filter": [ "lowercase", "asciifolding" ],
"text": "Is this déja vu?"
}
API 返回以下响应
{
"tokens": [
{
"token": "is",
"start_offset": 0,
"end_offset": 2,
"type": "<ALPHANUM>",
"position": 0
},
{
"token": "this",
"start_offset": 3,
"end_offset": 7,
"type": "<ALPHANUM>",
"position": 1
},
{
"token": "deja",
"start_offset": 8,
"end_offset": 12,
"type": "<ALPHANUM>",
"position": 2
},
{
"token": "vu",
"start_offset": 13,
"end_offset": 15,
"type": "<ALPHANUM>",
"position": 3
}
]
}
或者，在对特定索引运行 analyze API 时，可以引用 自定义 分析器
response = client.indices.create(
index: 'my-index-000001',
body: {
settings: {
analysis: {
analyzer: {
std_folded: {
type: 'custom',
tokenizer: 'standard',
filter: [
'lowercase',
'asciifolding'
]
}
}
}
},
mappings: {
properties: {
my_text: {
type: 'text',
analyzer: 'std_folded'
}
}
}
}
)
puts response
response = client.indices.analyze(
index: 'my-index-000001',
body: {
analyzer: 'std_folded',
text: 'Is this déjà vu?'
}
)
puts response
response = client.indices.analyze(
index: 'my-index-000001',
body: {
field: 'my_text',
text: 'Is this déjà vu?'
}
)
puts response
PUT my-index-000001
{
"settings": {
"analysis": {
"analyzer": {
"std_folded": {
"type": "custom",
"tokenizer": "standard",
"filter": [
"lowercase",
"asciifolding"
]
}
}
}
},
"mappings": {
"properties": {
"my_text": {
"type": "text",
"analyzer": "std_folded"
}
}
}
}
GET my-index-000001/_analyze
{
"analyzer": "std_folded",
"text": "Is this déjà vu?"
}
GET my-index-000001/_analyze
{
"field": "my_text",
"text": "Is this déjà vu?"
}
API 返回以下响应
{
"tokens": [
{
"token": "is",
"start_offset": 0,
"end_offset": 2,
"type": "<ALPHANUM>",
"position": 0
},
{
"token": "this",
"start_offset": 3,
"end_offset": 7,
"type": "<ALPHANUM>",
"position": 1
},
{
"token": "deja",
"start_offset": 8,
"end_offset": 12,
"type": "<ALPHANUM>",
"position": 2
},
{
"token": "vu",
"start_offset": 13,
"end_offset": 15,
"type": "<ALPHANUM>",
"position": 3
}
]
