Writing Custom handlers for solr in java

[star jlong]

Hi,

I'm a newbie on this fascinating technology called solr. Well, I have been 
doing some configurations and run with solr. Now I want to custom handlers for 
solr with java. Please can somebody share with an example of a custom handler 
for solr 5.2.0, so that with this example will be able to write more handlers.



Thanks,
Jstar.
