There are 1,178 pages in article space containing the word "it's". If you _really_ want to wade through them looking for the erroneous ones, go to the SQL query page and run:

SELECT cur_title from cur where cur_namespace=0 and cur_text regexp "[[:<:]]it's[[:>:]]" order by cur_title

It takes a while -- hence my idea to cut the list down in most cases!

Most of us can readily apply the following two rules:

• to show possession, it's correct to use: its
• we may change "it is" to its contraction: it's

So, I would like to be able to search for instances of:

it's

...so I can check whether it's being used as a contraction for "it is" (correct) or as a possessive (incorrect: change to "its").

But when I tried to use Wikipedia search, entering:

it's

I got a bunch of articles with the following 2 characters highlighted in red:

's

...which is a superset of what I want.

What is the correct search string to enter?
