使用python+whoosh实现全文检索

from whoosh.qparser import QueryParser 
from whoosh.index import create_in 
from whoosh.index import open_dir 
from whoosh.fields import * 
from jieba.analyse import ChineseAnalyzer 
from get_comment import SQL 
from whoosh.sorting import FieldFacet 
 
analyser = ChineseAnalyzer()  #导入中文分词工具 
schema = Schema(phone_name=TEXT(stored=True, analyzer=analyser), price=NUMERIC(stored=True), 
          phoneid=ID(stored=True))# 创建索引结构 
ix = create_in("path", schema=schema, indexname='indexname') #path 为索引创建的地址，indexname为索引名称 
writer = ix.writer() 
writer.add_document(phone_name='name',price ="price",phoneid ="id") # 此处为添加的内容  
print("建立完成一个索引") 
writer.commit() 
# 以上为建立索引的过程 
new_list = [] 
index = open_dir("indexpath", indexname='comment') #读取建立好的索引 
with index.searcher() as searcher: 
  parser = QueryParser("要搜索的项目，比如“phone_name", index.schema) 
  myquery = parser.parse("搜索的关键字") 
  facet = FieldFacet("price", reverse=True) #按序排列搜索结果 
  results = searcher.search(myquery, limit=None, sortedby=facet) #limit为搜索结果的限制，默认为10，详见博客开头的官方文档 
  for result1 in results: 
    print(dict(result1)) 
    new_list.append(dict(result1))
