force SOLR6 re/indexing from code

[LukaszRo]

Hi,

I have a problem with SOLR6 re/indexing.
I know that by default SOLR is re/indexed every 15 seconds and it is fine.
The challange I am facing is that I would like to force/trigger re/indexation process in the code for some created or modified nodes.
Is there a way to re/index node after being created or modified?
If it is possible, are there any threats connected with it?

Thank you in advance for solution or suggestion.

Ideally you don't have to force re-index from code. Indexes are eventually consistent. And if you see issues with index, you should try to re-index via solr admin console. 

Default interval for index tracking is 10 seconds (although docs says 15 seconds) and its configurable. 

You can partially re-index with help of 

/solr/admin/cores?action=SUMMARY&wt=xml , /solr/admin/cores?action=REPORT&wt=xml  

/solr/admin/cores?action=REINDEX&txid=3212 or /solr/admin/cores?action=FIX or /solr/admin/cores?action=RETRY

@abhinavmishra14 thank you for your response. I don't want to change solr index tracking configuration to make it more frequent (my need would be probably 1 second), because I am afraid that such frequent interval would slow down significantly the system.

The case is that  a end-user is creating/modifing a node and if that node is not re/indexed it wouldn't be showed at all or showed with not modified properties. My goal is to show the end-user up-to-date properties. That's why I would like to run re/index process from the code to show the end-user the changes he/she made.
