Search question

When i search the hamb on my computer, everything under the sun comes up like if i seach flat head, any post with the word flat or head in it will come up. when i hit the "search only in ***le" it does the same thing just within the ***le. I was using a different computer the other day and the search worked great, are there any search settings that i might have mixed up on my computer?


Thanks for all help,
Chris
