the regular expression was failing, this now works for me:

add_filter( 'posts_where', 'my_search_where' );

function my_search_where( $where ) {

    if ( is_search() ) {
    $where = preg_replace(
    "post_title LIKE $1) OR (post_excerpt LIKE $1", $where );

    return $where;

relevanssi works on a very different basis: it generates a table of indexed
terms which is updated when you save a post, and it then searches that table
rather than searching the posts table.
