Find Unique cell then copy to other sheets

Hi everyone, i a need a macro or formula to do the following:

Look up a match on sheet1 from individual cells from sheet2, and if match copy and paste to sheet3, and i need this to be done for every cell in sheet2.

Sort of a CTRL-F type of deal but for about 3000 individual cells on sheet2. The sheet1 contains about 10 columms with about 10000 cells all together. so to do this individually its just not posible.

Can any body help? thnx.
