Search bar in the Welcome topic page

What about this, from the Indigo layout, which provides what sounds like the functionality you're asking for.

<div class="frontpage-search-field" role="search" data-controller="SearchController:sc">

    <input class="wSearchField" type="text" data-class="no-filter: !@KEY_FEATURE.filter"

             data-attr="placeholder:  @KEY_LNG.Search; aria-label:@KEY_LNG.Search"

             data-value="KEY_SEARCH_TERM" data-focus="@focusin_searchbox(true)"

             data-blur="$sc.handleFocusOut('focusin_searchbox')|timeout:200"

             data-keyup="$mc.newSearch(node.value, event.keyCode),$sc.handleKey(event)|debounce:150"

             tabindex="7" /><a class="wSearchLink" data-click="@EVT_SEARCH_TERM(true)"

                                 data-attr="href:'#';aria-label: @KEY_LNG.SearchTitle"

                                 tabindex="8"><span aria-hidden="true"

                                                     data-html="@KEY-LNG.Search"

                                                     style="display: none;">&#160;</span></a>

    <div data-if="@focusin_searchbox" class="search-list">

        <table >

            <tr data-repeat="search_results" data-class="search-suggestion:true; search-selected:@selected===#{@index}"

                 data-click="$sc.handleClick(#{@index})">

                <td class="search-text-column"><div class="search-text"

                                                     data-itext="item.term">

                    <p>&#160;</p>

                </div></td>

                <td><div class="search-delete" data-if="$sc.canDelete(#{@index})"

                         data-click="$sc.handleDelete(#{@index})">

                    <p>&#160;</p>

                </div></td>

            </tr>

        </table>

    </div>

</div>

You'd need to build your own, but there are existing javascript and jquery plugins you can use (but takes some dev skill to work out how to include in your RH project).

Search for text highlighters. For example this one:

https://markjs.io/

One of the examples is a search bar with highlighting.

Using RoboHelp's own search, I would doubt it is possible and it would take a developer's skill to find out.

I have never seen anyone wanting to do this before so I don't think you will find an existing answer. My first thought was the box would go out of sight as soon as the user starts scrolling.

I'm wondering what the advantage is.
