我使用ElasticSearch 5.1.2作爲Heroku的Searchly插件,使用nodeJS包(https://github.com/elastic/elasticsearch-js)。 我試圖用菜單提示符匹配菜名。 我相信我遵循信函以下教程https://www.elastic.co/guide/en/elasticsearch/reference/5.1/search-suggesters-phrase.htmlElasticSearch短語提示器沒有返回結果
我可以在Searchly儀表板中看到我的商店包含數據。 但是,我的查詢從不返回任何結果,即使在搜索確切的短語時也是如此。
這裏是我的設置(CoffeeScript的):
elasticSearchClient.indices.exists index: 'dishes'
.then (indexExists) ->
if indexExists
elasticSearchClient.indices.delete index: 'dishes'
.then() ->
elasticSearchClient.indices.create index: 'dishes'
.then() ->
elasticSearchClient.indices.close index: 'dishes'
.then() ->
elasticSearchClient.indices.putSettings {
index: 'dishes'
body:
settings:
number_of_shards: 1
analysis:
filter:
shingle:
type: 'shingle',
min_shingle_size: 2
max_shingle_size: 3
analyzer:
trigram:
type: 'custom',
tokenizer: 'standard',
filter: ['standard', 'shingle']
reverse:
type: 'custom',
tokenizer: 'standard',
filter: ['standard', 'reverse']
}
.then() ->
elasticSearchClient.indices.open index: 'dishes'
.then() ->
elasticSearchClient.indices.putMapping {
index: 'dishes'
type: 'dishes'
body:
properties:
dishNameMatching:
type: 'text'
fields:
trigram:
type: 'text'
analyzer: 'trigram'
reverse:
type: 'text'
analyzer: 'reverse'
name:
type: 'string'
index: 'no'
flavorId:
type: 'string'
index: 'no'
}
這裏是我的查詢:
elasticSearchClient.suggest {
index: 'dishes'
body:
text: myText
dishSuggester:
phrase:
field: 'dishNameMatching.trigram'
size: options.limit or 5
gram_size: 3
direct_generator: [
field: 'dishNameMatching.trigram'
suggest_mode: 'always'
]
highlight: {
pre_tag: '['
post_tag: ']'
}
}
這裏是我所得到的,當我搜索 「與草莓醬薯片」:
results: {
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"dishSuggester": [
{
"text": "potato chips with strawberry jam",
"offset": 0,
"length": 49,
"options": [] # Should be some results here :-(
}
]
}
謝謝您的閱讀,我將不勝感激任何提示!
