Boolean notation I'm not so sure about, boolean variables however are binary - they only have two states, true and false, not sure if that helps at all.

alternatively one of these might be what you're after:
define: boolean - Google Search

Wildcards are like jokers in cards - they substitute for any other character. More relevently, if you do a search with a wildcard character it, for example "Duk*" it would search for anything with 'Duk' in it, but with anything else on the end, so "Dukat" would be a possible result.

If I remember right in SQL the way to select everything in a table is using a single wildcard character - for example "SELECT * FROM <table>" brings everything out of that table.

This might explain it better:
define: wildcard - Google Search

Hope this helps, not certain of the context though so if you can explain it a bit more I (or more likely someone else here) will beable to help more

Boolean is basically True/False you could say On/Off

Its in one state or the other not both how this is represented by notation is something I have never had to use maybe this link might help.

Boolean Notations


A good example of how you might use a wild card is not go into the search function of your computer and search for

*.jpg

The astrix is the wild card and it basically means "everything"

so searching for *.jpg will show every file with the .jpg extension

Hope that makes sense, and using it first hand might help you understand it's usage.....maybe

A Wildcard is kinda like when you receive an xmas card from me with a few pubes and a hippo's ear.

Boolean is that thing where you tickle her thighs whilst making fart noises...
