You are concatenating strings and new lines together, the "ShowModelSelectionMenuEx" works by looping through integers in each index - so try this:

pawn Код:

CMD:search(playerid, params[])
{
    new 
        items,
        string[128], 
        arrSearch[100]
    ;
    if (isnull(params)) 
        return UsageMessage(pid, "/search [query]");

    for (new i = 0; i != MAX_OBJECTS && items < sizeof(arrSearch); i ++)
    {
        if (strfind(allObjects[i][arname], params, true) != -1)
        {
            arrSearch[items++] = allObjects[i][arid];
        }
    }
    ShowModelSelectionMenuEx(playerid, arrSearch, items, "Search Results", Search);
    return 1;
}
