Definition of search filter
4 搜索过滤器的定义
It is possible to use one or more filters from message list. Under limitation from a group of conditions, filter is supposed to depend on message or variable. Seen from current message list, only wireless message is considered as that satisfying all conditions for inserting filter.
在消息列表上，有可能应用一个或多个过滤器。过滤器受一组条件限制，必须以消息或变量为依托。从目前的消息列表看，只有无线消息被认为是满足所有插入过滤器条件的消息。
For use of filter, it is necessary to call corresponding order via menu （filter> filter & search）or corresponding button in tool bar.
要应用过滤器，必须通过菜单（过滤>过滤搜索）调用相应的命令或工具栏上相应的按钮。

图十二 应用过滤器的按钮，展示在贴贴板上
Following dialog box will be shown.
将显示以下对话框
Figure13 Dialog Box for Use of Filter
图十三 应用过滤器对话框
Types of filters: temporary filter, variable value filter, packet filter and message filter
有几种类型的过滤器：临时过滤器，变量值过滤器，数据包过滤器，消息过滤器。
4.1 Definition of temporary search filter
4.1 临时搜索过滤器的定义
It is possible to select message received or sent in specific period via search filter. Time interval, designated date and time may be expressed by selecting the check box “enable temporary filter”. For example, message files in two lines may be filtered by method considering message in the first line.
通过搜索过滤器，有可能选择在特定临时阶段发出或收到的消息。通过选择复选框“启用临时过滤器”，有可能表达一个时间间隔，指定日期和时间。例如，两条线路的消息文件，有可能以考虑到关于第一线路消息的方式过滤消息。
Figure 14 Example of Temporary Filter Containing Files in Two Lines
图十四：关于包含两个线路文件的临时过滤器的示例
From Figure 14, we may find that the second line starts from 14:30:28, Sept 15, 2009. The time is applied in temporary filter.
看图十四，我们可以观察到第二条线路从2009-09-15 的 14:30:28开始。临时过滤器应用了这个时间：
Figure 15 Application of temporary filter
图十五 临时过滤器的应用
We acquired filtered data with trace of the first path.
我们获得了带有第一条路径痕迹的被过滤的数据：
Figure 16 Chart shown in application of temporary filter
图十六 通过应用临时过滤器显示的图表
4.2 Definition of variable value search filter
4.2 变量值搜索过滤器的定义
Three conditions may be farthest applied via single instruction.
通过一个单一的指令，有可能最大限度的应用三个条件：
When more than one condition is applied, AND will consider different conditions.
当应用不止一个条件时，不同的条件在AND中被考虑。
Therefore, when a filter satisfies condition A and B, all packets satisfying condition A and/or B will be selected.
所以 ，当一个过滤器在条件A、B下，所有满足条件A或B或者既满足A又满足B的数据包将被选中。
To define conditions of variable value filter, it is necessary to indicate name of variable intent to define conditions on its own, which may be selected by the current list in the field of “variable name”. All variables picked up from input file will be shown in the list.
为了定义变量值过滤器的条件，需要指出想要在此变量上定义条件的变量名称，这个名称可以在“变量名称”领域被当前列表选择。在此列表上将显示所有从输入文件提取的变量。
Figure 17 Example of Selecting Variable as Condition
图十七 根据条件选择变量的示例
Then due value of variable should be inserted to confirm conditions to be applied in field of “variable value”.
然后插入变量应有的值以便在“变量值”领域确认施加的条件。
All chart examples will show: value added to variable NID is 6.
所以在图表例子中显示：给变量NID附的值是6
Figure 18 Input of variable value
图十八 变量值的输入
Check box “match” indicates executable type of matching in the field of “variable value”. When the check box is not selected, it is considered that valuable value in “variable value” is identical to that indicated by “field of variable value”.
复选框“匹配”，在“变量值”领域指出可执行的匹配类型。当它没有被选中的时候，认为“变量名称”中变量值与“变量值领域”所指出的完全相同。
Thus in our example, value of NID is considered as 6.
所以在我们的例子中， 认为NID的值是6。
On the contrary, if the check box is selected, another type of comparison will be implemented. It is considered that variable value contains that indicated by “field of variable value”.
相反，如果复选框“匹配”被选中，则进行另一个类型的比较。认为变量值包含“变量值领域”所指出的变量值。
Figure 19 Conditions for Enabling Check Box
图十九 启用复选框匹配的条件
Therefore, following conditions are defined in the example in Figure 19:
所以在图十九的例子中，我们定义以下条件：
All messages where value of NID variable is 6 are selected thus all selected messages contains messages NID=6 and NID=16, NID=60 etc, in addition.
选择所有具有NID变量值含有6的消息，所以选择的所有消息不仅含有NID=6，而且包含NID=16，NID=60等等的消息。
Three conditions may be simultaneously applied in sole filter at most, which are put in AND.
在唯一的过滤器中，可以同时应用至多三个条件，这些条件放在AND中。
Figure 20 Filter Applying Three Conditions
图二十 应用三个条件的过滤器
All selected messages in example of Figure 20 meet following conditions:
在图二十的例子中，所有被选择的消息满足以下条件：
Variables NID = 6 & D_LRBG=1 & DATE contain value of 2006, where & is operator of AND.
NID = 6 & D_LRBG=1 & DATE变量包含2006的值。
哪里&旨在作为AND的运算符。
4.3 Definition of packet search filter
4.3数据包搜索过滤器的定义
It is possible select packet message via search filter. All messages with input type indicated may be selected via “packet” field shown in the figure below.
通过搜索过滤器，有可能选择出数据包消息。通过下图展示的“数据包”领域，有可能筛选出所有指出输入类型的消息。
Figure 21 Selection of Packet Message
图二十一 数据包消息的筛选
In examples of Figure 21 and Figure 22, filter of current list is applied to select all messages with packet 11.
在图二十一和二十二的例子中，应用了当前列表上的过滤器：筛选出所有具有数据包11的消息。
Figure 22 Apply Filter to Select All Messages with Packet 11
图二十二 应用过滤器选择含有数据包11的所有消息
Reified list is acquired in the example of Figure 23.
在图二十三的例子中，得到具体化的列表。
