Configuring Search in SharePoint Server 2013

Configuring Search in SharePoint Server 2013 is not a simple task. There are some critical options that need to be taken care of while configuring. Most of them are illustrated below:

From the Central Admin Home page click Manage service applications under Application Management…

In the Ribbon click New and select Search Service Application.

Name your Search Service Application and Select a service account

Next you’ll select or create an application pool for search.  I’m just going to run on a existing app pool to conserve resources.  If this were production I’d likely create a new app pool for both the search admin web service and the search query and site settings web service.

Click OK and wait…

Upon completion you’ll be presented with the following:

Note: the second time I configured the service app I accessed Central Admin from a computer that wasn’t part of the farm and it appeared to get hung up.  I then browsed to the service applications screen, search showed up just as it does below and everything works as it should.

Now we shall focus on Content Sources. On the Search Administration page there are several links broken into titled categories.  The second group is titled Crawling.

“A content source is a set of options that you use to specify what, when and how to crawl.”

When Search is initially configured the content source “Local SharePoint sites” is created, and as the name implies this includes all SharePoint sites in your farm.  As you create additional web apps they are automatically added to this content source.  Another thing to note is that changing your default AAM will result in that URL being added to your content source in addition to whatever the original URL of your site was, so there may be need for cleanup. 

This is also good to know, 

“Changing a content source requires a full crawl for that content source”

Clicking on Content Sources will bring you to the Manage Content Sources page…

Clicking on the dropdown will result in the following menu appearing…

  

Clicking Edit or on the Name will bring you to the edit content source page.

From this page your initial options are to name your content source, view content source details and add or remove start addresses.  Keep in mind that the Edit and Add pages are basically the same.  Obviously, you are going to need to click the New Content Source button to get to the Add Content Source page etc…   A start address is the point from which the crawler will begin to crawl your site.  Typically Local SharePoint sites is going to have all of your web apps listed by default.

Crawl Settings really only applies to when you are creating a content source because once you have selected a setting you can’t change it.  When creating a content source you have the following options.

Switching between the first 4 of these really just changes the path requirement, as illustrated in the screen shot below.

However, Line of Business data and Custom Repository require significantly different information…  Line of Business Data requires you to select a BCS Service application which of course requires that you have BCS provisioned and a Service Application is connected to some LOB System. 

More information on both source types can be found here…

And here…

A Custom Repository requires that you have a Custom Connector registered.

Your only edit options are,

“Crawl everything under the hostname for each start address”

Or

“Only crawl the Site Collection of each start address”. 

The second option would be used if you want to crawl some site collections in a web app less or more often than others.  There are several factors that would go into a decision like this.  For instance, varying content change frequency between site collections.

The next section deals with Crawl Schedules.  Crawl Schedules has the new option, Enable Continuous Crawls.

“Enable continuous crawls is a crawl schedule option that is new in SharePoint 2013. It is available only for content sources that use the SharePoint sites content source type. A continuous crawl starts at set intervals. The default interval is 15 minutes, but you can set continuous crawls to occur at shorter intervals by using Windows PowerShell.”

The familiar Incremental Crawl and Full Crawl scheduling options are next.  Both of which allow you to create a schedule.    Crawl schedules require a good bit of planning and are very much dependent on the specific needs of the environment.

Last we have Content Source Priority.  Your options here are High and Normal.  The Crawl system uses this to prioritize crawling resources with High content sources being top priority.

From a Content Source’s drop down menu the View Crawl Log options is available.

Clicking on this will bring you to the crawl log 

.

This screen provides you with Average Crawl Duration and Summary information.  This is where you go asses the health of your content source crawls, and is going to be your first stop when you need to troubleshoot content source issues.

Clicking on the number of errors will bring you to this page…

You will be taken to this same page, filtered appropriately, if you click on Warnings or Successes.  URL View allows you to search for crawled documents.  Databases provides a list of your crawl store databases and the number of items in each.  For more information I suggest reading this TechNet article…
