Solr delete not working for some reason
提问by Blankman
Just trying to delete all the documents, and did this:
只是试图删除所有文件，然后这样做：
http://localhost:8983/solr/update?stream.body=%3Cdelete%3E%3Cquery%3E*:*%3C/query%3E%3C/delete%3E
then committed:
然后承诺：
http://localhost:8983/solr/update?stream.body=%3Ccommit/%3E
I get the response:
我得到回应：
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">17</int>
</lst>
</response>
But when I search I still get results back.
但是当我搜索时，我仍然会得到结果。
What did I do wrong?
我做错了什么？

Not sure if it matters but you might encode the : too
不确定这是否重要，但您也可以对 : 进行编码
http://localhost:8983/solr/update?stream.body=%3Cdelete%3E%3Cquery%3E*%3A*%3C%2Fquery%3E%3C%2Fdelete%3E
Another thing to try is to use the POST method (the preferred way to call update):
另一件要尝试的事情是使用 POST 方法（调用更新的首选方式）：
curl http://localhost:8983/solr/update?commit=true -H "Content-Type: text/xml" --data-binary '<delete><query>*:*</query></delete>'

In Lucene wiki :
在 Lucene 维基中：
it will still be found, because index changes are not visible until, and a new searcher is opened. To cause this to happen, send a commit command to Solr (post.jar does this for you by default)
它仍然会被找到，因为索引更改是不可见的，直到打开一个新的搜索器。要导致这种情况发生，请向 Solr 发送提交命令（post.jar 默认为您执行此操作）
Maybe you can POST a <commit/>message to Solr.
也许您可以<commit/>向 Solr 发布一条消息。

Put the commit=true parameter in you GET request:
将 commit=true 参数放在您的 GET 请求中：
http://localhost:8983/solr/update?stream.body=%3Cdelete%3E%3Cquery%3E*:*%3C/query%3E%3C/delete%3E&commit=true
http://localhost:8983/solr/update?stream.body=%3Cdelete%3E%3Cquery%3E*:*%3C/query%3E%3C/delete%3E&commit=true

Remember to clear the browser cache! I thought I was having the same problem, but it turned out that the browser had just cached the result and was returning the cached page. D'oh!
记得清除浏览器缓存！我以为我遇到了同样的问题，但结果是浏览器刚刚缓存了结果并返回了缓存的页面。哦！

http://localhost:8983/solr/update?stream.body=<delete><query>*:*</query></delete>&commit=true
回答by whitehorse
Probably you are missing a forward slash (/) after update and before question mark.
可能您/在更新之后和问号之前缺少正斜杠 ( )。
Current query:
当前查询：
http://localhost:8983/solr/update?stream.body=<delete><query>*:*</query></delete>&commit=true
Revised query:
修改后的查询：
http://localhost:8983/solr/update/?stream.body=<delete><query>*:*</query></delete>&commit=true

I got stung with this one recently as well. Just remember that if you have updateLog is configured in solrconfig.xml, but there is no versionfield in the schema.xml
我最近也被这个刺痛了。只要记住，如果你在solrconfig.xml中配置了updateLog，但是schema.xml中没有version字段
see https://issues.apache.org/jira/browse/SOLR-3432
