How does Google hash a user’s search query? Obviously the hash is determined by the text in the query, but does google exclude common words like “the” or “a”. There are other factors to hashing a search term that could make it a faster process, such as not looping through each character in the term (if possible). Also, are other factors like the country in which the user reside play a role pre-hashing or post-hashing, in other words are other metrics besides the text of the query included in the hash?
In Java the function hashCode can be used to find the hash corresponding to the object passed as the implicit parameter. Would Google really just use a standard hashCode function?
I’m sure this is possibly one of Google’s “secrets”, but does anyone have an idea of how it’s done?
They remove the stop works from the query. Here is an article which talks about it.
