您需要做的是覆盖haystack的ElasticSearch后端中的搜索映射。
简而言之：扩展ElasticSearch后端，并直接替换或通过settings.py导入新模式映射进行替换。
from django.conf import settings
from haystack.backends.elasticsearch_backend import (ElasticsearchSearchBackend,
ElasticsearchSearchEngine)
class MyElasticBackend(ElasticsearchSearchBackend):
def __init__(self, connection_alias, **connection_options):
super(ConfigurableElasticBackend, self).__init__(
connection_alias, **connection_options)
MY_SETTINGS = {
'settings': {
"analysis": {
"analyzer": {
"ngram_analyzer": {
"type": "custom",
"tokenizer": "lowercase",
"filter": ["haystack_ngram"]
},
"edgengram_analyzer": {
"type": "custom",
"tokenizer": "lowercase",
"filter": ["haystack_edgengram"]
}
},
"tokenizer": {
"haystack_ngram_tokenizer": {
"type": "nGram",
"min_gram": 3,
"max_gram": 15,
},
"haystack_edgengram_tokenizer": {
"type": "edgeNGram",
"min_gram": 2,
"max_gram": 15,
"side": "front"
}
},
"filter": {
"haystack_ngram": {
"type": "nGram",
"min_gram": 3,
"max_gram": 15
},
"haystack_edgengram": {
"type": "edgeNGram",
"min_gram": 5,
"max_gram": 15
}
}
}
}
}
setattr(self, 'DEFAULT_SETTINGS', MY_SETTINGS)
class ConfigurableElasticSearchEngine(ElasticsearchSearchEngine):
backend = MyElasticBackend
