Apache Solr distributed search over SSL

Question

According to Solr documentation you can add "shards" parameter for distributed search in the following syntax:

host:port/base_url[,host:port/base_url]

How can I tell Solr to use https:// ?

Answer 1

So the answer is located in solrconfig.xml of your core:

<shardHandlerFactory class="HttpShardHandlerFactory">
    <str name="urlScheme">https://</str>
</shardHandlerFactory>

When you defining shards in your query

eg &shards=192.168.0.1:8983/solr/core,192.168.0.2:8983/solr/core

the shardHandlerFactory will prefix each server with specified value

in our case https://192.168.0.1:8983/solr/core and https://192.168.0.2:8983/solr/core .
