You'll have to give us more details on what exactly you are doing to
reproduce the problem you are seeing, and more detals on how exactly
you upgraded (and what version you upgraded from) ...

When i launch 6.3.0 using "bin/solr -e techproducts" I can index a
document with a blank string value, see the stored field in the result,
and search on that blank value just fine (see below)
Wild guess: perhaps when you upgraded you also changed the configs you are
using, and now have RemoveBlankFieldUpdateProcessorFactory in your default
updateRequestProcessorChain ?
What i tried with 6.3.0 ...
$ bin/solr -e techproducts
$ curl -H "Content-Type: application/json"
'http://localhost:8983/solr/techproducts/update?commit=true' --data-binary
'[{"id":"HOSS","blank_s":""}]'
{"responseHeader":{"status":0,"QTime":48}}
$ curl 'http://localhost:8983/solr/techproducts/query?q=id:HOSS'
{
"responseHeader":{
"status":0,
"QTime":5,
"params":{
"q":"id:HOSS"}},
"response":{"numFound":1,"start":0,"docs":[
{
"id":"HOSS",
"blank_s":"",
"_version_":1551101798705528832}]
}}
$ curl 'http://localhost:8983/solr/techproducts/query?q=blank_s:"";'
{
"responseHeader":{
"status":0,
"QTime":1,
"params":{
"q":"blank_s:\"\""}},
"response":{"numFound":1,"start":0,"docs":[
