一.安装并创建core

1.1安装

cd /usr/local/
wget http://mirrors.hust.edu.cn/apache/lucene/solr/7.7.3/solr-7.7.3.tgz
tar -zxvf solr-7.7.3.tgz# 启动
cd /usr/local/solr-7.7.3/bin
./solr start -force

1.2安装创建core

#### 环境添加core
cd /usr/local/solr-7.7.3/server# 添加自己的solr core
mkdir new_corecd /usr/local/solr-7.7.3/server/solr/configsets/_defaultcp -r ./conf /usr/local/solr-7.7.3/server/solr/new_core

界面添加core

二.pysolr操作solr

# 需要新建一个new_core不然会报错 步骤1.2
solr = pysolr.Solr('http://127.0.0.1:8983/solr/new_core', always_commit=True, )
# 查看solr是否能ping得通
# print(solr.ping())

2.1插入数据

for i in range(1,2000):solr.add([{"id": "doc_%d"%i,"title": "A TeST document","article": "my name is Cocktail_py%d"%i,"translation": "Nice to Cocktail_py%d"%i,},{"id": "doc_2","title": "The Banana: Tasty or Dangerous?","_doc": [{ "id": "child_doc_1", "title": "peel" },{ "id": "child_doc_2", "title": "seed" },]},])# 搜索new_core中的全部数据
results = solr.search('*:*')
print(results.docs)

2.2分页

# 假设一页返回10条数据
# 返回第一页
results = solr.search('*:*', start=0 * 10, rows=10)# 返回第二页
results = solr.search('*:*', start=1 * 10, rows=10)
print(results.docs)# 返回第三页
results = solr.search('*:*', start=2 * 10, rows=10)
print(results.docs)

2.3深分页 (基于排序进行)

# https://blog.csdn.net/weixin_42257250/article/details/97107933
# https://blog.csdn.net/asdfsadfasdfsa/article/details/80072533
# results = solr.search(q="""
# *:*
# &sort=id desc
# &cursorMark=*
# """)
results = solr.search(q='*:*', sort="id asc", cursorMark="*")# 获取原始数据
# raw_rep = results.raw_response
scroll_size  = len(results.docs)
data = results.docs
print(data)# 获取游标
nextCursorMark = results.nextCursorMarkwhile (scroll_size > 0):results = solr.search(q='*:*', sort="id asc", cursorMark=nextCursorMark)nextCursorMark= results.nextCursorMarkdata = results.docsscroll_size = len(data)print(data)

2.4模糊查询 (最普遍使用的模糊查询就是使用通配符)

# https://blog.csdn.net/qq_22929803/article/details/46924487
# 查询文章中含有cocktail_py的字符 似乎默认忽略大小写
results = solr.search('article:*cocktail_py*')
print(results.docs)# # 默认term并且忽略大小写
results = solr.search(q='title:bAnana', )

2.5完全匹配查询

# https://blog.csdn.net/babydavic/article/details/8657277
# 将关键字 用 双引号 包起来
results = solr.search('article:"Cocktail_py1018"')

2.6聚合查询

# https://blog.csdn.net/vtopqx/article/details/76099078
# http://localhost:8983/solr/solr_select/query?q=*:*&facet=on&facet.field=name
params = {"facet": "on","facet.field": "id",
}
results = solr.search(q="*:*", **params)
