Hi User,
EasyBlog's smart search results belongs to 'other' group, along with smart search results from other extensions/plugins. The magnifying glass serves as a generic icon for the various types of results under 'other' group, not just EasyBlog's.
If you want to modify it, you may template override the following theme file.
JoomlaFolder/components/com_easysocial/themes/wireframe/search/default/types/other.php
