Hey
when we use quotation marks in a search it means we are looking for a phrase so lets say we want to find cats jumping off a bed we can either look up cats jumping off a bed with no quotation marks and the algorithm will try to look for keywords in the search so cat bed and jumping (it ignores words like a and off) but the way it doses all this we will most likely find an image of a cat on a bed or jumping on a bed but we may not find one of the cat jumping off a bed. so this is where quotation marks come in they will make the algorithm look just for images and links tagged with "cat jumping off a bed"
the plus sign is when we want to add things to the search so we would use the plus sign if we wanted to find a cat that was on a bed and jumping it would be like this cat+bed+jumping
the pipe symbol is used when we are looking for two things that are basically the same but with one key difference so lets say we wanted cats jumping on a bed or dogs jumping on a bed we would use it then
and the words or and not can not be used in a search engine as the algorithm can not tell if they are being used as a tag.
