accented charachters

For “échouer”, no code is necessary. Relevanssi should find that with “échouer” or “echouer” (it may depend on your database collation, though).

The same does not apply to Arabic accents. You’re not the first one to ask about this, but if I’ve provided a solution to someone before, I can’t find it now.

You could give this a go:

add_filter( 'relevanssi_remove_punctuation', 'rlv_remove_arabic_diacritics' );
function rlv_remove_arabic_diacritics( $a ) {
    $a = preg_replace( '~[\x{064B}-\x{065B}]~u', '', $a );
    return $a;
}

Add this to your theme functions.php and rebuild the index. This does not convert “?” to “?”, but that’s not a diacritic, right, but instead two different letters? In that case, those kinds of conversions can be done using str_replace(), like this:

add_filter( 'relevanssi_remove_punctuation', 'rlv_remove_arabic_diacritics' );
function rlv_remove_arabic_diacritics( $a ) {
    $a = preg_replace( '~[\x{064B}-\x{065B}]~u', '', $a );
    $a = str_replace( '?', '?', $a );
    return $a;
}

(The symbols appear in the wrong order in the str_replace() on the forums, but they are in correct order, ie. ? first; the joys of mixing ltr and rtl alphabets…)

Tnx a lot Mikko
Sorry to bother you but please could you help me this questions too?

Is str_replace( replaces all ? in my database to ? so all word with ? will convert to words with ? or it just affect on search? I dont want any change to my database

and
if i add this lines
$a = str_replace( ‘?’, ‘?’, $a );
$a = str_replace( ‘?’, ‘?’, $a );
it works in a mutual way? namely if someone seach ? find ? and if search ? find ??

and
Is str_replace works with three side? for example ‘?’, ‘?’,’?’

This function is applied to the Relevanssi index and search queries, but your posts are not touched.

You only need to add it one way. The way this works is that both ? and ? will be indexed as ?, and all searches for both characters will automatically convert to ?. That way it’ll work both ways.

If you have more characters you want to match, just make them all convert to the same base form.
