Hello everyone. I changed the templates full-page-search.hbs and search-advanced-options.hbs

I want to change the icon in the button

<div class="control-group pull-left">
<label class="control-label" for="search-in-category">{{i18n "search.advanced.in_category.label"}}</label>
<div class="controls">
  {{search-advanced-category-chooser
    id="search-in-category"
    value=searchedTerms.category.id
    onChange=(action "onChangeSearchTermForCategory")
  }}
</div>
Now it looks like this
