我想知道是否可以搜索模式（更像是正则表达式模式）。
例如，在python中，正则表达式awk -v search="A 2,B 556" ' ##Starting awk program here, where mentioning a variable named search which will have your serach values in form of one_value, another_value etc.(as per OP post)
flag{ ##Checking condition if variable flag is NOT NULL then do following.
print array2[2],$2 ##Printing value of array2 element whose index is 2 and $2 of current line.
flag="" ##Nullifying variable flag here.
val=array2[2] ##Creating variable val whose value is array2 value with index 2 here.
}
{
num=split(search,array1,",") ##Splitting variable search into array1 whose delimiter is comma.
}
{
for(i=1;i<=num;i++){ ##Starting a for loop from i=1 to till value of num(which is length of array1).
split(array1[i],array2," ") ##Splitting array1 value of index i with delimiter space into array2.
if($1==array2[1] && $2==array2[2]){ ##Checking condition if array2 with index 1 value equals to $1 and array2 with index 2 value equals to $2.
flag=1 ##Setting variable flag value to 1 here.
next ##Using next keyword of awk to skip all further statements from here.
}
}
}
' Input_file ##Mentioning Input_file name here.
将返回“ Food”之类的单词。我想使用谷歌搜索引擎做同样的事情。
我的问题“有可能实现这一目标吗？”。
答案 0 :(得分：1)
否，Google当前不允许部分单词搜索。当我说Youtube或Gmail时，我一再发现这是必需的。
