This works great for one search
{exp:search:simple_form channel="artists" search_in="everywhere" status="open" where="all" result_page="search/searchresults" no_result_page="search/noresults"}
<div id="searching">
<input type="text" id="searchbox" name="keywords" placeholder="Search Artists"/>
<button id="search" name="submit" type='submit'><i class='icon-search'></i></button>
</div>
{/exp:search:simple_form}and this for another works great for one search
<div id="searching">
<input type="text" id="searchbox" placeholder="Search Projects" name="keywords" />
<!-- hidden values to search everything in News with Category Project -->
<input type="hidden" name="search_in" value="everywhere" />
<input type="hidden" name="where" value="all" />
<input type="hidden" id="channel_id" name='channel_id[]' value="7" />
<input type="hidden" id="cat_id" name="cat_id[]" value="45">
<button id="search" name="submit" type='submit'><i class='icon-search'></i></button>
</div>BUT I want to combine them into one.
A search that looks in both the Artists channel and the news channel (one catergory)
Is this possible ? Thanks
