1，Categorize paginated documents. [launch codename "Xirtam3", project codename
$ n4 _/ E1 U& |' P, F"CategorizePaginatedDocuments"] Sometimes, search results can be dominated bydocuments from a paginated
series. This change helps surface more diverse results in such cases.
7 Z: I  F- M& _6 z7 ~1，對於頁碼性文檔的歸類。
某些時候，搜索結果會有很多由一系列頁碼產生的文檔構成。此項改變將使得這種情況下，有更深層次的結果能顯
現。（註：頁碼性文檔，我的理解是，例如，某個文章比較長，分成幾個頁面顯示，就會產生很多類似的url，唯
) L. R/ a' l6 X$ S8 @8 D. X4 R一的區別就是頁碼不同，而這次的這項改動，google將會對有頁碼相關性的頁面有更好的理解）

# ~1 f: `: `' h3 |More language-relevant navigational results. [launch codename "Raquel"] For navigational searches when
the user types in a web address, such as [bol.com], we generally try to rank that web address at the top. However,
this isn』t always the best answer. For example, bol.com is a Dutch page, but many users are actually searching in
8 N& [) t* H4 l8 o/ q5 G4 fPortuguese and are looking for the Brazilian email service, http://www.bol.uol.com.br/. This change takes into
account language to help return the most relevant navigational results.
2，對於導航性結果將更多考慮相關的語言結果。
對於導航性搜索，例如用戶在地址欄中輸入【bol.com】，我們一般會嘗試將那個網址顯示在頂部。然而，這並不
8 t" U: i) n  Y# X2 U總是能呈現最好的答案。例如，bol.com是荷蘭文頁面，但多數用戶實際是以葡萄牙語搜索的，尋找的是巴西的郵
件服務-http://www.bol.uol.com.br/。這次的改變，將把語言相關也考慮進去，從而能返回最相關的導航性結果。

  Country identification for webpages. [launch codename "sudoku"] Location is an important signal we use
0 u8 A4 a7 c8 b2 ~to surface content more relevant to a particular country. For a while we』ve had systems designed to detect
; M5 E6 v' U% Uwhen a website, subdomain, or directory is relevant to a set of countries. This change extends the
granularity of those systems to the page level for sites that host user generated content, meaning that some
pages on a particular site can be considered relevant to France, while others might be considered relevant
. L3 m7 a" [5 _* jto Spain.
3，對於頁面歸屬國家的辨認。
地理位置是我們用來判斷對於一個特定國家內容顯示的一個重要信號。我們曾有過一些系統來辨認是否一個網站，
- [- V  }0 V1 g低級域名或目錄是否相關一系列國家。本次改變進一步細化了這些系統，達到了網站的用戶生成內容的頁面級別。
+ A* v# s) X! l! Y+ y' ^即，在特定網站內，有些頁面將被認為與法國更相關，而另外一些則被認為和西班牙更相關。

diverse set of domains.
$ o! J2 e/ _$ N$ {# i% o, _; d) ~5 _: i4 {5，更強的域名差異性。
有時搜索結果會從同一個域名返回太多的結果。本次改變將使得不同系列的域名結果得到更多的顯示。

you』ll find an organization website from your country (e.g. mexico.cnn.com for Mexico rather than cnn.com).
6，更多的本地網站。

% }% o1 @2 p8 S  Improvements to local navigational searches. [launch codename "onebar-l"] For searches that include
location terms, e.g. [dunston mint seattle] or [Vaso Azzurro Restaurant 94043], we are more likely to rank
, U: ^! c% {8 P  r$ wthe local navigational homepages in the top position, even in cases where the navigational page does not
mention the location.
7，改進了本地導航類搜索的結果。
對於搜索中包含本地詞彙，如[dunston mint seattle]  或[Vaso Azzurro Restaurant 94043]，我們會更加傾向於把當

most fundamental signals used in search is whether and how your search terms appear on the pages you』re
searching. This change improves the way those terms are scored.
8，對於搜索詞語在排名中的積分方法的改進。
在搜索中一個最重要的信號就是，是否您搜索的詞在頁面上出現以及怎樣出現。本次改動改進了這類詞語的積分方

updates our system for generating snippets to keep it consistent with other infrastructure improvements. It
also simplifies and increases consistency in the snippet generation process.
9，取消了snippets中的salience。(註：salience是顯著的意思，這裡不合適，故未譯)
本次改變更新了我們用於生成snippets的系統，使得其與其他設施改進能一致。它還簡化並增加了snippet生成步
驟的連續性。

  More text from the beginning of the page in snippets. [launch codename "solar", project codename
"Snippets"] This change makes it more likely we』ll show text from the beginning of a page in snippets when
that text is particularly relevant.
10，在snippets頁面開始處顯示更多文字。
此項改變會使得我們更傾向於顯示snippets頁面開始部分的文字（當其特別相關時）。

# H) q( h& u* ^2 j8 E26，國際範圍內糟糕的拼寫改正將更少。
當您搜索例如【mango tea】,  我們將不再給出像「Did you mean mint tea?」這樣的拼寫預測。我們調整了

! ?" a) H& Q& _1 v! R5 _
$ G, E4 Z7 b6 H0 A  More spelling corrections globally and in more languages. [launch codename "pita", project codename
"Autocomplete"] Sometimes autocomplete will correct your spelling before you』ve finished typing. We』ve

/ Q8 A, z9 ^- Q! ?( Nof this feature to cover more than 60 languages.
27，全球範圍的拼寫改正將更多，支持更多語言。

  More spell corrections for long queries. [launch codename "caterpillar_new", project codename

28，對於較長搜索請求的拼寫改正將更多。

( q1 ]7 V" x, _& J+ ?  More comprehensive triggering of 「showing results for」 goes international. [launch codename

: R7 o2 W5 Y& |; T# V+ N6 D- c8 L0 d3 othe results you find will actually be results for the corrected query, 「pneumatic.」 In the past, we haven』t
  y9 W; e+ h# g) y  a9 Ralways provided the explicit user interface to say, 「Showing results for pneumatic」 and the option to 「Search

these cases in English, and now we』re expanding that to new languages.
: U9 E" D( U/ v( Q) B9 y29，全球範圍內的「showing results for」觸發因素更理性化。
      有時，您打錯了一個單詞在搜索框，例如[pnumatic]，那麼顯示的結果將是被改正的搜索結果—[pneumatic]。

  「Did you mean」 suppression goes international. [launch codename "idymsup", project codename
"Spelling"] Sometimes the 「Did you mean?」 spelling feature predicts spelling corrections that are accurate,
6 c# c5 l4 T$ N. sbut wouldn』t actually be helpful if clicked. For example, the results for the predicted correction of your search
; t& C! |) f9 ^may be nearly identical to the results for your original search. In these cases, inviting you to refine your
# x8 x5 U2 L# I+ nsearch isn』t helpful. This change first checks a spell prediction to see if it』s useful before presenting it to the
user. This algorithm was already rolled out in English, but now we』ve expanded to new languages.  
: T( z& z0 C7 C0 s. L7 Y! W! W) o8 H30，「Did you mean」擴展至更多語言。 （即，原先的詞語更正提示，現在已經擴展至更多語言）
