Well, context word finding is a bit more complicated than this, I can try to copy paste the same function we use in the core, but this may not work at all:

function x_context_find($str, $needle, $context, $maxlength, $str_length_limit = 10000, $false_on_no_match = false) {
	$haystack = remove_accents(' '.trim($str).' ');
	$haystack = wd_substr_at_word(ASP_mb::strtolower($haystack), $str_length_limit, '');
	$needle = remove_accents(ASP_mb::strtolower($needle));

	if ( $needle == "" ) {
		if ( ASP_mb::strlen($str) > $maxlength) {
			return wd_substr_at_word($str, $maxlength);
		} else {
			return $str;
		}
	}
	$chrArray = preg_split('//u', $haystack, -1, PREG_SPLIT_NO_EMPTY);
	$hay_length = count($chrArray) - 1;

	if ( $i = ASP_mb::strpos($haystack, $needle) ) {
		$start=$i;
		$end=$i;
		$spaces=0;

		while ($spaces < ((int) $context/2) && $start > 0) {
			$start--;
			if ($chrArray[$start] == ' ') {
				$spaces++;
			}
		}

		while ($spaces < ($context +1) && $end < $hay_length) {
			$end++;
			if ($chrArray[$end] == ' ') {
				$spaces++;
			}
		}

		while ($spaces < ($context +1) && $start > 0) {
			$start--;
			if ($chrArray[$start] == ' ') {
				$spaces++;
			}
		}

		$str_start = ($start - 1) < 0 ? 0 : ($start -1);
		$str_end = ($end - 1) < 0 ? 0 : ($end -1);

		$result = trim( ASP_mb::substr($str, $str_start, ($str_end - $str_start)) );

		// Somewhere inbetween..
		if ( $start != 0 && $end < $hay_length )
			return "... " . $result . " ...";

		// Beginning
		if ( $start == 0 && $end < $hay_length )
			return $result . " ...";

		// End
		if ( $start != 0 && $end == $hay_length )
			return "... " . $result;

		// If it is too long, strip it
		if ( ASP_mb::strlen($result) > $maxlength)
			return wd_substr_at_word( $result, $maxlength );

		// Else, it is the whole
		return $result;

	} else {
		if ( $false_on_no_match )
			return false;

		// If it is too long, strip it
		if ( ASP_mb::strlen($str) > $maxlength)
			return wd_substr_at_word( $str, $maxlength );

		return $str;
	}
}

function asp_context_find( $results, $search_id, $is_ajax, $args ) {
	foreach ($results as $k=>&$r) {
		$r->content = x_context_find($r->content, $args['s'], floor(ASP_mb::strlen($r->content) / 6), 130);
	} 
	return $results;
}
add_filter( 'asp_results', 'asp_context_find', 10, 4 );
