SharePoint 2013 Search Farm Installation Architecture Matrix

Image
General Guideline: SharePoint 2013 Search Farm installation general guideline. So how would be the search farm structure? To installation each component in farm that you need to analysis the number of item in your organization. So if the content less < 10 mil then 2 index component and 1 partitioned per 10 mil items,  2 Query, 2 content processing, 2 Analytic, 1 crawl database and 1 link database. 
For the performance issues:
Crawl time and result freshness: Add crawl database and content processing component for improve the crawl time and result freshness.Result time: For query latency add more index replica and for query throughput add more partition
Use the following matrix to configure Search Farm

Use 2 Crawl Component Use 2 Search Administrator ComponentNumber of Analytic database varies depend upon the usage

Issue Solved: Missing Fast Search Center Template

Image
Today we encounter an issue related to the "Fast Search" missing template.

When we creating the site collection by going into the central admin and select the "Fast Search" template the default the "Fast Search Template" feature activated and this template is available for all the sub sites as well. The problem comes when we creating the site collection other than this template like "teamsite" template. The "Fast Search Template" feature is deactivated by default. So
we unable to find the search template under this site collection, for that we would req. to activate this feature manually.

So we need to run the following Power shell.

$site = Get-SPSite -Identity http://Sp2010/sites/Search
$site.Features.Add("5EAC763D-FBF5-4d6f-A76B-EDED7DD7B0A5")

So the “Search Bound Variable” that you find most of the places during the search configuration & you also wanted to know they it is working and interaction during the query processing.

Search bound variables: The search bound variables are the place holders. So the most common search bound variables are following.

As showing below image in comes the search "cameras images" the {searchboxquery} text is "cameras images". When the query transforms the {searchboxquery} breaks in {subjectTerms} and the "{actionTerms}" to the below example during the query rules the "cameras" is treated like the {subjectTerms} and "images" become {actionTerms}.
