Impoved Search - Added check for comperations (<,>,<=,=<,>=,=>)

[UtechtDustin]

I impoved the search checks so comperations search (<,>,<=,=<,>=,=>) are possible now.
This feature was requested by @ManicPumpkin on Issue #3042.

The following comperations are possible:

> value
< value
<= value
=< value
>= value
=> value
value <
value >
value <=
value =<
value >=
value =>

Thanks for your contribution!

It seems that there are problems in this case, let's see how to improve it.

[UtechtDustin]

I fixed the bug (working example), also i improved the documentation about searching (description of the 3 search types (contains, strict and comparison)).

Thanks! Fixed the lint errors: d6b1c78.

@wenzhixin
My fault i already fixt hat lint errors, but forgott to push it...sorry!
Can you explain me why all ; will removed, is there a good reason for that or just to save some memory ?

[wenzhixin]

Because other ES6 projects remove ;, so use the same rules, each line can be one less character :)
Also, refer to some of the more popular projects, they also do not use ;.
For examples:
https://github.com/twbs/bootstrap/blob/master/js/src/alert.js
https://github.com/vuejs/vue/blob/dev/src/core/index.js
