Hi Ram,
If you want to open search Results in new tab , You have to update Item_CommonItem_Body.html Display Template. Search for below line :
var titleHtml = String.format('<a clicktype="{0}" id="{1}" href="{2}" class="ms-srch-item-link" title="{3}" onfocus="{4}" {5} >{6}</a>',
$htmlEncode(clickType), $htmlEncode(id + Srch.U.Ids.titleLink), $urlHtmlEncode(url), $htmlEncode(ctx.CurrentItem.Title),
showHoverPanelCallback, appAttribs, Srch.U.trimTitle(title, maxTitleLengthInChars, termsToUse));
and replace it with :
var titleHtml = String.format('<a clicktype="{0}" id="{1}" href="{2}" class="ms-srch-item-link" title="{3}" onfocus="{4}" {5} target="_blank">{6}</a>',
$htmlEncode(clickType), $htmlEncode(id + Srch.U.Ids.titleLink), $urlHtmlEncode(url), $htmlEncode(ctx.CurrentItem.Title),
showHoverPanelCallback, appAttribs, Srch.U.trimTitle(title, maxTitleLengthInChars, termsToUse));
upload it and publish it again. Now search results will open in new tabs.
Thanks,
Lalita
