无法使用发布工具或 URL 删除 solr 文档（使用查询）

Question

I am not able to delete solr documents (using a query) either using post tool or URL.

Please note, my solr is configured with basic authentication.
Solr Version : 6.6

I tried two ways,

1. Using post tool

./post -u username:pass -c core_name delete_by_timestamp.xml here delete_by_timestamp.xml looks like,

<delete>
   <query>timestamp:[* TO 2017-04-03T10:30:30Z]</query>
</delete>

This gives me 401 Unauthorized response

2. Using the URL,

http://username:pass@{ip_address}:8983/solr/core_name/update?stream.body=<delete><query>timestamp:[* TO 2017-04-03T10:30:30Z]</query></delete>&commit=true

This gives me NullPointerException ,

java.lang.NullPointerException at 
org.apache.solr.query.SolrRangeQuery.createDocSet(SolrRangeQuery.java:156) at 
org.apache.solr.query.SolrRangeQuery.access$200(SolrRangeQuery.java:57) at 
org.apache.solr.query.SolrRangeQuery$ConstWeight.getSegState(SolrRangeQuery.java:412)

Any help would be appreciated. Thanks in advance.

Answer 1

Use one of the queries below in the Document tab of Solr Admin UI:

XML:

<delete><query>*:*</query></delete>

JSON:

{'delete': {'query': '*:*'}}

Make sure to select the Document Type drop down to Solr Command (raw XML or JSON).

I answered a similar question. Let's try this.

I tried the below steps. It works well.

• Please make sure the SOLR server it running

• Just click the link Delete all SOLR data which will hit and delete all your SOLR indexed datas then you will get the following details on the screen as output.

   <response> <lst name="responseHeader"> <int name="status">0</int> <int name="QTime">494</int> </lst> </response>

• if you are not getting the above output then please make sure the following.

  • I used the default host (localhost) and port (8080) on the above link. please alter the host and port if it is different in your end.
  • The default core name should be collection / collection1 . I used collection1 in the above link. please change it too if your core name is different.
