在Whoosh中保存索引

Question

我正在寻找一个建议，或者最好是一个例子，来存储或保存呼呼的索引。我在Windows 7专业版上使用Python 2.7。如果有人能帮忙的话。

Answer 1

Whoosh有很好的文档记录，您可以在Official documentation中找到大多数内容。以下是快速入门中的Indexer-Searcher示例：

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

# Searcher 
>>> from whoosh.qparser import QueryParser
>>> with ix.searcher() as searcher:
...     query = QueryParser("content", ix.schema).parse("first")
...     results = searcher.search(query)
...     results[0]
...
{"title": u"First document", "path": u"/a"}

该示例在details there中进行了解释。
