Scenario: Develop search based applications or pages that pull data based on query string
Solution: In SharePoint2013 and SPO search based applications\solutions are in rise. On a single web page with minimal coding we can pull variety of data from multiple sources including different SiteCollections.
Consider below Query String that we can append to page URL
#k=Language%3D%22English%22
When we URL decode, it looks like below:-
#k=Language="English"
OR ?k=Language="English" AND Language="Hindi"
OR ?k=Language:"English" OR Language:"Hindi"
On a single webpage we can add Script\Code, multiple CSWPs and other search related web parts and configure them to pull data related to above Query String parameter.
For example, I can add a CSWP on to a page and configure its query as below:-
{SearchBoxQuery} path:"https://sharepoint.com/teams/mydevsite" ContentClass:sts_web
The above query returns all the websites in a site collection specified in the "path" attribute. When user navigates to this page from a different page with above query string parameter, it only displays websites that are tagged with "Language = English"
On the same page we can also drag and drop Script Editor web part and using REST or JSOM we can pull data from a List Or Document library tagged with "Language = English".
In CSWP we can have below different type of query:-
path:"https://sharepoint.com/teams/mydevsite"
(Language={QueryString.Language} OR
RefinableString00={QueryString.RefinableString00} )
The above query shows all kinds of data including subsites, Documents etc. from Site Collection specified in the path. In the URL you can append query string like:-
?Language=English
It then show all types of content tagged with "English" Language.
