Improved support for Japanese coded sites (charset: SHIFT_JIS, EUC-JP and UTF-8).

Template design 'Pure' reduced to 'like Google'.

Improved search algorithm: significantly reduced search time.

Improved support for Greek language:

1. Transliterate queries with Latin characters into their Greek equivalents.

   Will for example transform query input alla to find ἀλλὰ and baptismatos to find βαπτίσματος.

2. Accept Greek queries containing vowels without accents.

   Query input of letter α will be valid also for

   ἀ, ἁ, ἂ, ἃ, ἄ, ἅ, ἆ, ἇ, ὰ, ά, ά, ᾀ, ᾁ, ᾂ, ᾃ, ᾄ, ᾅ, ᾆ, ᾇ, ᾰ, ᾱ, ᾲ, ᾳ, ᾴ, ᾶ and ᾷ

   The same behavior for all other Greek vowels, as well as for the upper case vowels.

   Both options will create a tolerant result listing.

New options in 'Add site' and 'Edit site' menus:

- Enter URL of individual Sitemap

If Sitemap is not in root folder, the URL of the individual Sitemap could be entered.

New option to manipulate the result listing:

For result sorting 'By URL names' the number of results shown per domain is selectable.

Offers result presentation similar to 'Like Google', but additionally offers a selectable count of links.

Search option 'More results from this domain' not only enabled for result sorting 'Like Google', but also for 'By URL names'.

Bug fixed that prevented correct interpretation of http 301 redirects.

Bug fixed that causes invalid results for multiple word queries, which contain numbers, like 'price 25 euro'.

Bug fixed that prevented highlighting of keywords, if found in position 0 of title or full text.

Bug fixed that prevented suppressing of 'Show result scores' in Admin settings.

Bug fixed that prevented to follow the option 'temporary ignore no-index'.
