Atomic update by query instead of ID

[Saumitra Srivastav <sa...@gmail.com>]

Is is possible to update a single field in multiple documents through atomic
updates, using a query instead of ID?

Here's my use case:

I have a multivalued field called 'tags' and a text field called 'content'.
User can define a pattern(regex) and name it, say my_pattern. Value
'my_pattern' should be added in 'tags' field in all the documents which have
that pattern in 'content' field.

Only way to do this is to get 'ID's of all the matched docs and send
individual atomic updates like mentioned in 
https://wiki.apache.org/solr/Atomic_Updates
<https://wiki.apache.org/solr/Atomic_Updates>  

But this will not scale when we have lots of matching documents. So is there
a way to specify a *query* for atomic updates, something like:

curl http://localhost:8983/solr/update -H 'Content-type:application/json' -d
'
[{
  "query"  : "content:pattern",
  "tags"    : {"add":"my_pattern"}
 }]'

I am using Solr 4.8.1 in cloud mode.

Saumitra

No, but it sure would be nice to have the Elasticsearch feature of supplying 
a script for update.
