using a custom update for all documents
Hello everyone,
Is there a way to update all the documents in the solr index using a custom
update processor?
Thank you,
Roxana

to answer your specific question...
>> Subject : Re: using a custom update for all documents
..you can configure any <updateRequestProcessorChain> as default="true"
and it will be used regardless of wether it is specified by name in the
update request using the update.chain param...
https://lucene.apache.org/solr/5_3_1/solr-core/org/apache/solr/update/processor/UpdateRequestProcessorChain.html
But again, i reierate Alexandre's higher level concern...
https://people.apache.org/~hossman/#xyproblem
XY Problem
Your question appears to be an "XY Problem" ... that is: you are dealing
with "X", you are assuming "Y" will help you, and you are asking about "Y"
without giving more details about the "X" so that we can understand the
full issue. Perhaps the best solution doesn't involve "Y" at all?

Roxana,
You've been asked a couple of times by several people to explain your
business needs (level higher than Solr itself). As it is, you are
slowly getting deeper and deeper into Solr's internals, where there
might be an easier question if we know what you are trying to achieve.
It is your choice of course, but it might be easier to step back to
reconfirm what you are trying to actually achieve beyond the Solr
technicalities.
Regards,
Alex.

Thank you very much, Upayavira.
I am indexing my documents with a DIH, but I need to use my custom update
processor after the commit, not in the update.chain.
Do update processors only work while adding new documents?
In this case, I have tried two alternatives:
1) using the onImportEnd event. However I need to restart solr to see my
current updates. Is there any way to inform solr that it needs to reload
the searcher?
2) re-importing the indexed documents using SolrEntityProcessor and adding
my custom chain processor. Which is the best approach?
Best,
Roxana

You want to re-index all documents?
If so, that's not really how update processors work. They trigger when a
new document is posted. You would need, somehow, to post every document
again in order to trigger the update processor's ability to do its work.
