索引管理
from elasticsearch import Elasticsearch
es = Elasticsearch(['http://localhost:9200'])
# 创建索引并指定映射
mapping = {
"mappings": {
"properties": {
"title": {"type": "text", "analyzer": "english"},
"content": {"type": "text"},
"author": {"type": "keyword"},
"created_at": {"type": "date"},
"views": {"type": "integer"}
}
}
}
es.indices.create(index='articles', body=mapping)
# 索引文档
doc = {
"title": "Elasticsearch Guide",
"content": "Complete guide to Elasticsearch",
"author": "John Doe",
"created_at": "2024-01-01",
"views": 100
}
es.index(index='articles', id=1, body=doc)
# 批量索引
from elasticsearch.helpers import bulk
actions = [
{"_index": "articles", "_id": i, "_source": doc}
for i, doc in enumerate(documents)
]
bulk(es, actions)
搜索查询
# 全文搜索
query = {
"query": {
"match": {
"content": "elasticsearch guide"
}
}
}
results = es.search(index='articles', body=query)
# 布尔查询
bool_query = {
"query": {
"bool": {
"must": [
{"match": {"content": "elasticsearch"}}
],
"filter": [
{"range": {"views": {"gte": 100}}}
],
"should": [
{"term": {"author": "john-doe"}}
],
"must_not": [
{"term": {"status": "draft"}}
]
}
}
}
# 多字段匹配查询
multi_match = {
"query": {
"multi_match": {
"query": "elasticsearch guide",
"fields": ["title^2", "content"], # 提升标题权重
"type": "best_fields"
}
}
}
# 模糊搜索
fuzzy = {
"query": {
"fuzzy": {
"title": {
"value": "elasticseerch",
"fuzziness": "AUTO"
}
}
}
}
