usage使用

\Yii::$app->redisfilter->getTagList($tag,$offset,$limit); $tag param：

• string, just the tag set 字符串就是对应的tag集合
• array, deep loop each array and interstore key and value, then unionstore all element results. 数组情况则key与value取交集，然后所有数组元素取并集，可以嵌套

['a','b'=>['c'=>['d','e'=>'f']]] means a|(b&c&(d|(e&f))

//set tags 设置标签
$rf = \Yii::$app->redisfilter;
$rf->setTag($a->id, 'base', $a->created_time); //all article sort by created_time 所有文章按时间排序
$rf->setTag($a->id, 'samsung'); //all article tag into tag sets 所有文章按标签类型贴收入对应集合
$rf->removeTag($b->id, 'base');

//filter tags 筛选标签
//by page 按分页
$ids = $rf->getTagList(['seta','setb'=>'setc'],$offset,$pageSize); // seta|(setb&setc) 
//$ids  array(11) { [0]=> string(7) "1385584" [1]=> string(7) "1385585" [2]=> string(7) "1385586" [3]=> string(7) "1385587" [4]=> string(7) "1385588" [5]=> string(7) "1385589" [6]=> string(7) "1515910" [7]=> string(7) "1515911" [8]=> string(7) "1515912" [9]=> string(7) "1515913" [10]=> string(7) "1515914" }

//by score 按分数
$zsetname = $rf->getZset(['base'=>'samsung']); // base&samsung
$total = $rf->getTagTotalByZset($zsetname);
$ids = $rf->getTagListByScore($zsetname, time()-86400*3, time());
