Search word document contents

hi, this goes along with a recent post someone made on searching the source code of a file…but rather than source code, i need to search the contents of a word document with php…any possibility of this?

basically, a user would upload a word document, and another user would be searching for the policy “AC3999-AB” which is inside this word document…the online app would search this document and return the file.

or i could initally load all the contents of the file into a table in the db and search that…but how do i load the contents of the word document into the table in the first place?
