Copyright 2004-2011 Aspose Pty Ltd.Copyright 2004-2011 Aspose Pty Ltd. 截断符： “$”，可以右截断检索词。用户可能并不知 某一检索词的精确拼写法，而只知道一个词根。 这种情况下，用户只需给出一个检索词词根，而 不必给出一个确定的检索词。右截断检索词用在 词根后紧跟一个“$”符号来标识。例如：在作者 字段中输入张$，则表示姓张的所有作者。 Evaluation only.Evaluation only.

Copyright 2004-2011 Aspose Pty Ltd.Copyright 2004-2011 Aspose Pty Ltd. 字段相邻运算符： (G)：限定两个检索词在同一字段内（即使是 可重复字段也当作一个字段来处理）。比如：制 碱(G) 理论, 这就要求命中集合中的记录某一字 段内即含有检索词“制碱”又含有检索词“理论 ”。 (F)：限定两个检索词在同一字段内的同一重 复内出现，是比 (G)更加严格的限定。一般使用 (G)即可。 Evaluation only.Evaluation only.

Copyright 2004-2011 Aspose Pty Ltd.Copyright 2004-2011 Aspose Pty Ltd. （2）操作限定符说明： 可以使用操作限定符来规定一个或多个检索词出 现在某一字段或某一组字段内，这对于不同字段含有 相同检索词的数据库尤其有用。限定符的一般格式为 ：检索词/(t1，t2，t3，.) 其中t1，t2，t3.是一组字 段标识符，它限定检索词出现在这些字段中。 例如：石油/(200,300),即将石油限定在200或300字段 。 操作限定符与逻辑算符连用，以限制检索在规定 的字段内进行。此外还可以将操作限定符用于右截断 检索词中。 Evaluation only.Evaluation only.

Copyright 2004-2011 Aspose Pty Ltd.Copyright 2004-2011 Aspose Pty Ltd. （3）布尔表达式的句法说明： 使用上面所介绍的运算符，将两个或两个以上检索词组 合在一起，可以组成复杂的布尔达式。与一般的代数一样， 可以用括号来改变运算的顺序。上面所介绍的算符的优先级 自高而低为：$、(F)、(G)、*和、+。如果在同一表达式的 同一级括号中，有两个或两个以上的优先级相同的算符出现 ，则按从左到右的顺序计算。 在组合检索式时，除了相邻运算符“和“?“能重复出现 外（这两个算符不能混合出现），两个逻辑算符不能彼此相 邻；括号必须成对出现。即开括号的数目必须等于闭括号的 数目，且每个开括号都有相匹配的闭括号。注意有括号或逻 辑运算符（*、+、(G)、(F)、$、等）或以数字符号开始的 检索词必须用双引号“括起来，以免引起错误。比如，检 索词为： GERMANY (FEDERAL REPUBLIC) 就必须按下面的方 式输入：“GERMANY (FEDERAL REPUBLIC)“ 否则就会出现语法 错误。 Evaluation only.Evaluation only.
