2012年亚洲最热门的搜索词汇是什么？
标点符号将搜索词汇分割成单独的可搜索片断，如清单26所示。
Punctuation characters split the search term into separately searchable fragments, as shown in Listing 26.
注意短语搜索(以双引号表示的搜索词汇)会返回相同的结果。
Note that a phrase search (enclosing the search terms in double quotes) returns the same results.
在词元方面的搜索扩展会直接应用到搜索词汇中，但不会递归作用。
The search expansion on lemmas is applied to the search term directly, not recursively.
这些技术通常是成功的，尤其是在与精心挑选的搜索词汇配合使用时更是如此。
These techniques are often successful, especially when used in combination with careful choices of search terms.
全文搜索查询中的搜索词汇的分析方式类似于索引过程中的分析方式。
The search terms in a full-text search query are analyzed similarly to the analysis done during the indexing process.
这样的搜索会作为一个短语搜索，所以包含搜索词汇变形的文档不会返回。
The search is applied as a phrase search, so documents that contain an inflection of the search term are not returned.
对于最小查询，有效的搜索词汇至少由两个字符组成，而且它们不能只包含标点符号。
For minimal queries, valid search terms consist of at least two characters, and they cannot contain punctuation marks only.
例如，当您使用我们的搜索引擎的时候，我们会记录哪些是最常用的搜索词汇。
For example, when you use our search engine, we may keep track of which search terms are popular.
特定的字符在搜索查询中有特定的语法意义，如果想要作为搜索词汇，那么它们需要进行转义修饰。
Certain characters have semantic meaning as part of the search query, and they need to be escaped if they are intended to be part of a search term.
这些新网页也可以通过搜索引擎检索到，同时也可以因这些新的搜索词汇而增加你的网站的整体曝光度。
The new pages will also be indexed by the search engines and should enhance your overall online visibility for new search terms.
相对应地，在一个关键字搜索中，首先确认搜索词汇的词元，然后所有包含这个词元的文档都会被返回。
Correspondingly, for a keyword search, the lemmas of the search term are identified, and all documents containing that lemma are returned. For example.
标点和符号集是用来替换其他字符的，即使搜索词汇是包含在双引号中，或者标点符号被转义了，如清单25所示。
The set of punctuation and symbols substitute for other members of the set, even if the search term is enclosed in double quotes, or the punctuation is escaped, as shown in Listing 25.
根据搜索词汇的复杂度和基础数据仓库的大小，任何特定查询返回的匹配集都可能十分庞大，以致于无法使用。
Depending on the level of search-term sophistication and the size of the underlying data store, the return set of matches for any particular query may be so large as to be unusable.
例如，如果您需要有关创建新插件的帮助，搜索词汇“plug - in”，Help搜索就会返回一系列同查询相匹配的内容——包括备忘单和其他的内容。
For example, if you want help on creating a new plug-in, a help search for the term "plug-in" will return cheat sheets — along with other content — that match your query.
