If you use the g:paginate tag and there is only one page it outputs nothing. This makes sense because there is no pagination to render.

But typically your page would still have a pagination section, even if there is only one page.

So you have to add a (cut and pasted) calculation of the number of pages AND an if/else, AND a span mimicking the current page in the real paginate tag output (to benefit from your existing CSS):

Page:
    <g:set var="totalPages" value="${Math.ceil(searchResult.total / searchResult.max)}" />
    <g:if test="${totalPages == 1}"><span class="currentStep">1</span></g:if>
    <g:else><g:paginate controller="searchable" action="index" 
                        params="[q: params.q]" total="${searchResult.total}"
                        prev="&lt; previous" next="next &gt;"/></g:else>

This violates DRY in a number of ways.

So the tag should have an optional "renderSinglePage=true|false" attribute, or similar, so the above code becomes

Page:
    <g:paginate controller="searchable" action="index" 
                params="[q: params.q]" total="${searchResult.total}"
                prev="&lt; previous" next="next &gt;" renderSinglePage="true" />
