WordPress search has the option to search multimple words
/?s=searchtring1+searchstring2
Is it possible to have 2 list of preselected searchkeywords as a dropdown and have wordpress press search those?
I have tried
<form role="search" method="get" id="searchform" action="<?php bloginfo('siteurl'); ?>">
<div>
<label class="screen-reader-text" for="s">Search for:</label>
Type
<select name='s' id='type' class='postform' >
<option value='' selected='selected'>All</option>
<option class="level-0" value="dog">Dog</option>
<option class="level-0" value="cat">Cat</option>
</select>
Color
<select name='s' id='color' class='postform' >
<option value='' selected='selected'>All</option>
<option class="level-0" value="red">red</option>
<option class="level-0" value="white">white</option>
<option class="level-0" value="green">green</option>
</select>
<input type="submit" id="searchsubmit" value="Search" />
</div>
</form>
But the output is
/?s=row1&s=row2
rather than
/?s=row1+row2
