Any package for boolean search?

[Jean Louis <bugs@gnu.support>]

Hello to all,

Boolean Search: This is a method where search terms are combined using
boolean logic, as described by the operators AND, OR, and NOT.

I would like to implement this classic into the website search. And I
wish to keep it simple.

Here are 20 different queries using boolean search operators AND, OR, and NOT:

1. `apple AND fruit`
2. `car OR truck`
3. `not google`
4. `(apple OR banana) AND fruit`
5. `football NOT soccer`
6. `book AND author`
7. `(dog OR cat) NOT animal`
8. `house AND (furniture OR decor)`
9. `google AND (search OR engine)`
10. `not (car OR truck)`
11. `(phone OR laptop) AND technology`
12. `flower AND (garden OR plant)`
13. `(music OR video) NOT entertainment`
14. `amazon AND (shopping OR online)`
15. `not (phone OR computer)`
16. `(camera OR photo) AND equipment`
17. `travel AND (hotel OR resort)`
18. `(newspaper OR magazine) NOT media`
19. `(game OR puzzle) AND entertainment`
20. `(coffee OR tea) AND (breakfast OR morning)`

I think if there are no parenthesis I should even disregard the OR, is
it right?

I wish there would be some ready made package that handles those
issues.
