I want to write a custom Solr query and sorting and when I am calling
http://127.0.0.1:8983/solr/techproducts/select?q={!myparsername}12&sort=uid
desc, some of the section as marked is not getting called.
Issue: Documentation of solr customization is pretty poor
Help: Can you please tell why my code is not getting called.
Why I needed customization: Based on logged in user info like user age,
location and 10 other parameters I need to sort. Also, need sorting value
for tagging.
Default Solr expression is very costly.
