Using angularJS for testing, ng-reapt="pro in products | filter:search" A particularly big question
For the following test, why does typing search in the a input box produce results

When you do not specify which field to filter, the default filter will match the values of all fields. When you enter a, angular should convert false into a string by default, and a matches false. If you change the filter conditions to this
If you type a, there will be no results. What it means is that only the value of the name field is filtered.
Because
ng默认把你product里三个字段key，name，is_in_presale都转成字符串和你的输入去比较了，所以a其实匹配到的是false里的a。你可以试试输入true, I can feel the difference in results.If you need to specify fields for
filter, please refer to the document:Or just look at my plunker
