SharePoint 2013 offers rich API for interacting with Managed Navigation. Unfortunately, some additional work is required if you need to use it with anonymous users.
Copying Site Collections in SharePoint 2013 is trivial, except if you are trying to copy a Host Named Site Collection with multiple SPSiteUrls.
Recently I wrote a blog post on how standard Managed Properties are not enough for supporting particular scenarios. For example, when building content aggregations sorted on dates or numbers you would need a custom Managed Property. The reason for that is the fact that, although there are some Refinable and Sortable Managed Properties available out of the box with SharePoint, despite the type communicated in Search Schema, they return string data which makes them useless for sorting on numbers.
Content recommendations are a great way of increasing exposure of your content. And although they just work out of the box, there is a little inconvenience when using them on a website with subwebs.
SharePoint 2013 Search contains rich capabilities that help you find the relevant content. What if however you already know what you are looking for and just want to get a link to it?
