Creating Solr shards in Alfresco 6.1 CE - alfresco

Question

After migrating to Alfresco CE 6.1 (201901 GA) and Alfresco Search Services we have massive search performance problems. So I tried to configure sharding in solr by following Creating Solr shards manually.
I was able to create the shards and indexing seams to work but when I configure Alfresco to use sharding in alfresco-global.properties
solr6.store.mappings.value.solrMappingAlfresco.nodeString=solr.mycompany.com:8983/solr/#/alfresco
solr6.store.mappings.value.solrMappingAlfresco.numShards=4
solr6.store.mappings.value.solrMappingAlfresco.replicationFactor=1
solr6.store.mappings.value.solrMappingArchive.nodeString=solr.mycompany.com:8983/solr/#/archive
solr6.store.mappings.value.solrMappingArchive.numShards=4
solr6.store.mappings.value.solrMappingArchive.replicationFactor=1
I get a "Request failed 405"
/solr/#/alfresco-2/alfresco?wt=json&fl=DBID%2Cscore&rows=50&shards=solr.mycompany.com:8983%2Fsolr%2F%23%2Falfresco-0,solr.mycompany.com:8983%2Fsolr%2F%23%2Falfresco-1,solr.mycompany.com:8983%2Fsolr%2F%23%2Falfresco-2,solr.mycompany.com:8983%2Fsolr%2F%23%2Falfresco-3&df=TEXT&start=0&locale=*&alternativeDic=DEFAULT_DICTIONARY&sort=%40cm%3Amodified+desc&fq=%7B%21afts%7DAUTHORITY_FILTER_FROM_JSON&fq=%7B%21afts%7DTENANT_FILTER_FROM_JSON

For better readability the decoded POST url to solr:
/solr/#/alfresco-2/alfresco?wt=json&fl=DBID,score&rows=50&shards=solr.mycompany.com:8983/solr/#/alfresco-0,solr.mycompany.com:8983/solr/#/alfresco-1,solr.mycompany.com:8983/solr/#/alfresco-2,solr.mycompany.com:8983/solr/#/alfresco-3&df=TEXT&start=0&locale=*&alternativeDic=DEFAULT_DICTIONARY&sort=#cm:modified+desc&fq={!afts}AUTHORITY_FILTER_FROM_JSON&fq={!afts}TENANT_FILTER_FROM_JSON
Was anybody already successfully in configuring sharding in Alfresco Search Services (1.3.x, 1.4) and Alfresco 6.1 Community?
Does anybody have a hint what is going wrong? Alfresco seems not to use the solr standard urls for searching in the sharded index so I'm somehow lost how to get this working.

Answer 1

to answer my own question:
the example Creating Solr shards manually doc example should be without the hash sign in the url but does not work if solr runs with SSL support.
solr6.store.mappings.value.solrMappingAlfresco.nodeString=solr.mycompany.com:8983/solr/alfresco
solr6.store.mappings.value.solrMappingAlfresco.numShards=4
solr6.store.mappings.value.solrMappingAlfresco.replicationFactor=1
solr6.store.mappings.value.solrMappingArchive.nodeString=solr.mycompany.com:8983/solr/archive
solr6.store.mappings.value.solrMappingArchive.numShards=4
solr6.store.mappings.value.solrMappingArchive.replicationFactor=1
as an alternative it is possible to use the DynamicShardRegistration which is not documented to work in the community version but is working if you set
useDynamicShardRegistration=true
in alfresco-global.properties
