问题描述
当尝试搜索奇数不。的单词与我的木瓦分析仪没有结果显示。
'新德里abcd '不返回任何结果，但'新德里abcd xyz
我的分析器看起来像下面
{
search：{
settings：{
index：{
analysis：{
filter：{
my_shingle_filter：{
max_shingle_size：2，
min_shingle_size：2，
output_unigrams：false，
type ：shingle
}，
autocomplete_filter：{
type：edge_ngram，
min_gram：1，
max_gram ：40
}
}，
分析器：{
my_shingle_analyzer：{
filter：[
smallcase，
my_shingle_filter
]，
type ：custom，
tokenizer：whitespace
}，
shingle_with_autocomplete：{
filter：[
smallcase，
my_shingle_filter，
autocomplete_filter
]，
type：custom，
tokenizer：whitespace
}
}
}
}
}
}
}

解决方案
这是一个<在ES 5.2.x中的href =https://github.com/elastic/elasticsearch/issues/23346 =nofollow noreferrer>错误。问题是新版本中的单个过滤器
When trying to search with odd no. of words with my shingle analyzer no result shows up.
'new delhi abcd' does not return any results but 'new delhi abcd xyz' returns
My analyzers look like below
{
"search": {
"settings": {
"index": {
"analysis": {
"filter": {
"my_shingle_filter": {
"max_shingle_size": "2",
"min_shingle_size": "2",
"output_unigrams": "false",
"type": "shingle"
},
"autocomplete_filter": {
"type": "edge_ngram",
"min_gram": "1",
"max_gram": "40"
}
},
"analyzer": {
"my_shingle_analyzer": {
"filter": [
"lowercase",
"my_shingle_filter"
],
"type": "custom",
"tokenizer": "whitespace"
},
"shingle_with_autocomplete": {
"filter": [
"lowercase",
"my_shingle_filter",
"autocomplete_filter"
],
"type": "custom",
"tokenizer": "whitespace"
}
}
}
}
}
}
}
The mapping for the type is shared below
{
"search": {
"mappings": {
"address": {
"properties": {
"full_address": {
"type": "text",
"norms": false,
"fields": {
"edge_n_grams": {
"type": "text",
"norms": false,
"analyzer": "autocomplete"
},
"shingles": {
"type": "text",
"norms": false,
"analyzer": "shingle_with_autocomplete"
},
"synonym": {
"type": "text",
"norms": false,
"analyzer": "synonym_autocomplete"
}
},
"analyzer": "whitespace"
}
}
}
}
}
}
Query 1
GET search/address/_search?_source=full_address
{
"query": {
"match": {
"full_address.shingles": {
"query": "new delhi",
"analyzer": "my_shingle_analyzer"
}
}
}
}
Results
{
...
"hits": {
"total": 21801,
"max_score": 8.015874,
"hits": [{
"_index": "search",
"_type": "address",
"_id": "581c50297fd84ecc35420570",
"_score": 8.015874,
"_source": {
"full_address": "new delhi nagar palika adarsh vidyalay new delhi nagar palika adarsh vidyalay tilak lane tilak marg area new delhi delhi 110001"
}
}, {
"_index": "search",
"_type": "address",
"_id": "581c502a7fd84ecc35422010",
"_score": 7.013889,
"_source": {
"full_address": "kingdom hall of jehovant witness gyan bharti public school saket new delhi new delhi delhi 110017"
}
},
...
]
}
}
Query 2
GET search/address/_search?_source=full_address
{
"query": {
"match": {
"full_address.shingles": {
"query": "new delhi nag",
"analyzer": "my_shingle_analyzer"
}
}
}
}
Results
{
...,
"hits": {
"total": 0,
"max_score": null,
"hits": []
}
}
'new delhi nagar pal' returns proper results.
Any help/insights would be appreciated
