Figure 4 shows you an example of DNT strings and a good practice of keyword expression because the strings combined without Spaces between words such as WebSite are usually keywords.
图4显示了dnt字符串的一个例子，以及一种很好的关键字表达方式，这种方式将单词组合成字符串，中间不留空格(例如WebSite通常是关键字)。
The data is then indexed using techniques such as XML pattern expression indexing, B-tree structural indexing, structural indexing, content or keyword indexing, and others.
然后，数据被使用诸如XML模式表达式索引、B-树结构索引、结构索引、内容或关键字索引之类技术以及其他技术进行索引。
A transform expression starts with the optional "transform" keyword followed by a COPY, MODIFY, and a RETURN clause.
转换表达式的开头是可选的“transform”关键字，然后是COPY、MODIFY和return子句。
The return value expression must start on the same line as the return keyword in order to avoid semicolon insertion.
如果返回表达式，则表达式应与return关键字在同一行，以避免误加分号错误。
Regular expressions: search word (s) will be regarded as a regular expression (in keyword search words will be treated as a sequence of regular expressions).
正则表达式：搜索单词将作为一个正则表达式(在关键字搜索中，单词被视为正则表达式系列)。
The default clause specified can be either a constant, a special register, another global variable, an expression or the keyword NULL.
默认指定的子句可以为一个常量、一个特殊的寄存器、另一个全局变量、一个表达式或关键字 NULL。
The first parameter is described using a regular expression and represents the keyword triggering the client to retrieve XML documents from the database.
第一个参数是一个正则表达式，它代表触发客户机从数据库获取XML文档的关键字。
The keyword can be a literal, such as calculator, or a regular expression, such as calc*.
关键字可以是字面值（比如 calculator），也可以是正则表达式（比如 calc*）。
Both work fundamentally the same way, at compile time the keyword "var" is replaced with the correct scalar or array type for the associated expression.
二者的实现基础完全相同，即在编译时将“var”替换成为分析得到的正确的变量或数组类型表达式。
It consists of the keyword attribute followed by the desired attribute name, plus an expression for the attribute value. You see this in Update 15.
它包括关键字attribute、所需的属性名和属性值的表达式，见更新15。
The default clause specified can be either a constant, a special register, another global variable, an expression or the keyword NULL.
默认指定的子句可以为一个常量、一个特殊的寄存器、另一个全局变量、一个表达式或关键字NULL。
Now, the main techniques are also devised by methods based on keyword match and used semantic, the techniques are pressed for information about expression of relation between concepts.
目前常用的反馈技术依然是基于关键词匹配的方式，基于语义的方式缺少概念之间关系的描述。
