Feeds from hash tag doesn't display in chronological order

HI

When we click on any tag it redirects to hashtagprofile.aspx which is present in layouts.It displays all feed associated with that tag. 

In the aspx page we have contentbysearch webpart which is tagged to the querygroupname "HashTag_TaggedItems" as shown below 

<SearchWC:ContentBySearchWebPart QueryGroupName="HashTag_TaggedItems" id="TaggedItems" runat="server" FrameType="None" 
ResultsPerPage=5
ShouldHideControlWhenEmpty="true" 
RenderTemplateId="~sitecollection/_catalogs/masterpage/Display Templates/Content Web Parts/Control_List.js" 
SelectedPropertiesJson="[&quot;Title&quot;, &quot;Path&quot;, &quot;Author&quot;, &quot;FileExtension&quot;, &quot;SecondaryFileExtension&quot;, &quot;ViewsRecent&quot;]" 
PropertyMappings="'Link URL':'Path','Line 1':'Title','Line 2':'','FileExtension','SecondaryFileExtension'"
ItemTemplateId="~sitecollection/_catalogs/masterpage/Display Templates/Content Web Parts/Item_TwoLines.js"
GroupTemplateId="~sitecollection/_catalogs/masterpage/Display Templates/Content Web Parts/Group_Content.js"/>

Now the issue is that the feed which this webpart display is not in chronological order.I think it is based upon rank which is really weird so I wanted that is there any way that we can fix this.

I don't want to modify the page since it is OOB.

Can we know which result source it is using and modify that source and add sorting in that.
