Sitecore 8.1 index rebuild strategy for SOLR search provider
<p>Just read through the index update strategies document below but couldn't get the clear answer on which strategy is best for SOLR search implementation:</p>

<p><a href="https://doc.sitecore.net/sitecore_experience_platform/search_and_indexing/index_update_strategies" rel="noreferrer">https://doc.sitecore.net/sitecore_experience_platform/search_and_indexing/index_update_strategies</a> </p>

<p>We have setup the master and slave Solr endpoints where master will be used for create/update. And slave for reading only.</p>

<p>Appreciate if you could suggest the indexing strategy to be used for:</p>

<ol>
<li><p>Content Authoring</p></li>
<li><p>Content Delivery</p></li>
</ol>

<p>Solution is hosted in azure web apps and content delivery can be scaled up or down from 1-N number at any time.</p>

<p>I'm planning to configure below:</p>

<ol>
<li>Only CA have a OnPublishEndAsync</li>
<li>All CDs will not have any indexing strategy.</li>
</ol>

<p>Appreciate if you could suggest a solution that has worked for you. Also how do we disable indexing strategy?</p>

<p>Thanks.</p>
