Sitecore converting Lucene to Solr

Question

Currently, I have lucene search engine in my sitecore 8 instance. It is working perfectly but something change in our production servers. The production servers now are 2 content delivery server with load balancing and a content management server.

I read that it is difficult to use lucene in this kind of architecture. They are suggesting to use Solr instead of lucene.

I am able to setup solr with the help of this post. It is working perfectly and I able to create indexes for sitecore_web_index, sitecore_master_index, sitecore_core_index and sitecore_analytics_index.

What I am having trouble is converting my custom search index configuration to SOLR configuration (schema.xml).

My search index configuration contains computed fields and an include template (<include hint="list:IncludeTemplate">) that index only those specific fields.

Question:

How to create sitecore computed fields in SOLR (schema.xml)?
How to index only a particular template?

<include hint="list:IncludeTemplate">
       <page>{GUID}</page>
</include>

I already checked the samples in solrTutorial.com but can't find what I am looking for (Noob!).

Looking forward to learn from you guys.

UPDATE:

Implementing the suggestion of nsgocev I received the error below:

Update 2:

Looks like setting the Initialize on Add to true cause the problem:

<initializeOnAdd>true</initializeOnAdd>

Please let me know what I am missing.

Thanks,

Basically using computed fields is the same like using it with your Lucene indexes. The idea is to add your fields in your Sitecore.ContentSearch.Solr.* configurations instead in your Sitecore.ContentSearch.Lucene.* configurations. In the Solr configs (Most likely the Sitecore.ContentSearch.Solr.DefaultIndexConfiguration.config) there should be <fields hint="raw:AddComputedIndexField"> section where you just need to add your computed field like this:

 <fields hint="raw:AddComputedIndexField">
     ...
     <field fieldName="mycomputedfield"             returnType="string">YourNamespace.MyComputedField, YourAssembly</field>
 </fields>

Same goes for indexing on a particular template. There is a list in the same configuration file (commented out by default)

<!-- <include hint="list:IncludeTemplate">
    <BucketFolderTemplateId>{ADB6CA4F-03EF-4F47-B9AC-9CE2BA53FF97}</BucketFolderTemplateId>
</include>-->
