How by search to level one letter to another?

[Lunat]

In Russian there are two letters the difference in which is insignificant ("е" and "ё"). How by search to level one letter to another?

... mmm ...
... if I understand you not quite right ... then sorry ...
... but the 4images-search is a word-search not a letter-search ...
... and by default you need 3 letters as a minimum for your search ...
... so the search find only the words with the right letter "e" or  "ё" ...
... so, where is the problem ... ?

[Lunat]

Problem in that letters mean one and too! And if I enter "елка" 4images will not find to me "ёлка".
PS. "ёлка" means "fur-tree"

... but this is not a problem with 4images and Russian language ...
... I think,  the problem ist between keyboard and chair ...
... if I enter in German language "Ara" (engl. a bird) 4images will not find "Ära" (engl. era) ...
... sorry, so I can't see any 4images problem ...

(I've attached modified search_utils.php file just in case)
This should do the trick with newly added images. For the already added images you might want run the [Plugin] Rebuild search index.
These changes also fix problem with capital russian letters - PHP doesn't change case for russian letters unless server's locale is set to CP1251 or KOI8, so searching for "ёлка" will not find image with name "Ёлка".


@mawenzi:
in russian if a word has a letter "ё" it is grammatically correct write that word with such letter, however it is acceptable replace that letter with letter "е" without loosing the meaning.
Even though  these two letters pronounce differently ("e" = "je" and "ё" = "jo"), if "e" used in such word we still pronounce it as if it was "ё" ("елка" and "ёлка" pronounce the same and have same meaning). So for search engines it is a good thing see no difference between letter "e" and "ё".

... if I enter in German language "Ara" (engl. a bird) 4images will not find "Ära" (engl. era) ...

This is correct simply because by default 4images supports deutsch:

Code: [Select]

function convert_special($text) {
  return strtr(
    $text,
    array(
      "Ä" => "AE",
      "Ö" => "OE",
      "Ü" => "UE",
      "ä" => "ae",
      "ö" => "oe",
      "ü" => "ue",
      "ß" => "ss"
    )
  );
}
in search_utils.php

P.S.
"ёлка" = "Christmas tree"
