Two Search Boxes: one all content, one only titles
It was not so hard and I have solved the problem, so for any one else stuck, just add: if ( isset($_GET[‘search-type’]) == ‘by-ref’ ) { add_filter( ‘posts_search’, ‘__search_by_title_only’, 500, 2 ); } where ‘by-ref’ is set in form as input type=”hidden” name=”search-type” value=”by-ref”
Search a post using the date it was posted

And do a custom query for these $_GET values: $date_query = new WP_Query( ‘year=” . $_GET[“year’] . ‘&monthnum=’ . $_GET[‘month’] . ‘&day=’ . $_GET[‘day’] ); Then your custom loop: <?php if … Read more

Is there a wordpress plugin enabling an autocomplete search box, then jump to page?
You could use the autocompleter plugin. It does exactly what you describe: it autocompletes half-typed tags and categories. You’d just need to tag your recipes with their ingredients.
Remove WHERE conditions from search query
Filter posts_where or posts_search. See this answer for a couple of examples.
get_search_form() doesn’t appear to take parameter into account
this might be the cause: The $echo parameter is ignored when searchform.php is present. There is a issue in the WordPress Trac concerning this. from the codex: http://codex.wordpress.org/Function_Reference/get_search_form#Notes

Multiple Category Search
I found the solution… My functions page now looks like: <?php class dropdown extends Walker_CategoryDropdown { function start_el(&$output, $category, $depth, $args) { $pad = str_repeat(‘ ’, $depth * 3); $cat_name = apply_filters( ‘list_cats’, $category->name, $category ); $output .= “\t<option class=\”level-$depth\” value=\””.$category->slug.”\””; $output .= ‘>’; $output .= $pad.$cat_name; if ( $args[‘show_count’] ) $output .= ‘ (‘. $category->count .’)’; … Read more
Including Custom Meta with posts_where query
Well I managed to solve this sort of… The answer was to use separate search input boxes for each custom field being searched. Here is my working solution if anyone ever stumbles across this. function display_all_products() { global $term; $term = trim(strip_tags($_POST[‘s’])); $refnoterm = trim(strip_tags($_POST[‘ref’])); $yrterm = trim(strip_tags($_POST[‘yr’])); if(!empty($_POST[‘s’]) || !empty($_POST[‘ref’]) || !empty($_POST[‘yr’])) { if(!empty($_POST[‘s’])) … Read more
