Question

import os, os.path
from whoosh.index import create_in
from whoosh.fields import *
schema = Schema(title=TEXT(stored=True), path=ID(stored=True), content=TEXT)

if not os.path.exists("indexdir"):
    os.mkdir("indexdir")


ix = create_in("indexdir", schema)
writer = ix.writer()
writer.add_document(title=u"First document", path=u"/a",
                 content=u"This is the first document we've added!")
writer.add_document(title=u"Second document", path=u"/b",
                 content=u"The second one is even more interesting!")
writer.commit()
from whoosh.qparser import QueryParser

with ix.searcher() as searcher:
    query = QueryParser("content", ix.schema).parse("first")
    results = searcher.search(query)
    results[0]

看起来没问题，但它没有显示任何结果。

Answer 1

我想你最后一行是：

print results[0]

Answer 2

Python要求您使用print显式打印输出：

print results[0]

但请注意，上面的代码适用于Python 2.x.在Python 3.x中，print已转换为function：

print(results[0])

程序未显示任何输出
