Whoosh索引查看器 [英] Whoosh index viewer

问题描述

我正在使用带有whoosh的haystack作为Django应用程序的后端。

I'm using haystack with whoosh as backend for a Django app.

有什么方法可以查看内容（以易于阅读的格式）由whoosh生成的索引？我想看看索引了哪些数据，以及如何更好地理解它是如何工作的。

Is there any way to view the content (in a easy to read format) of the indexes generated by whoosh? I'd like to see what data was indexed and how so I can better understand how it works.

推荐答案

您可以执行此操作从python的交互式控制台非常容易：

You can do this pretty easily from python's interactive console:

>>> from whoosh.index import open_dir
>>> ix = open_dir('whoosh_index')
>>> ix.schema
<<< <Schema: ['author', 'author_exact', 'content', 'django_ct', 'django_id', 'id', 'lexer', 'lexer_exact', 'published', 'published_exact']>

您可以直接在索引上执行搜索查询，并做各种有趣的事情。要获得每个文档，我都可以这样做：

You can perform search queries directly on your index and do all sorts of fun stuff. To get every document I could do this:

>>> from whoosh.query import Every
>>> results = ix.searcher().search(Every('content'))

如果全部打印出来（供查看或其他），您可以使用python脚本轻松完成。

If you wanted to print it all out (for viewing or whatnot), you could do so pretty easily using a python script.

for result in results:
    print "Rank: %s Id: %s Author: %s" % (result.rank, result['id'], result['author'])
    print "Content:"
    print result['content']

您也可以直接从飞快移动返回文档django视图（也许可以使用django的模板系统进行漂亮的格式化）：有关更多信息，请参阅whoosh文档： http ：//packages.python.org/Whoosh/index.html 。

You could also return the documents directly from whoosh in a django view (for pretty formatting using django's template system perhaps): Refer to the whoosh documentation for more info: http://packages.python.org/Whoosh/index.html.
