compare two cells

Column A....................................Column B
6858 3/4 in hcs hex die.................die 1-7/16" 3/4-10nc
20729 hex die 9/16-18nf................die 1-7/16" 9/16-18nf
5/8 in hcs hex die.........................die 1-7/16" 5/8-18nf
hex die 3/4-16nf............................2x4-8 SPF


I have a spreadsheet with 17,000 lines. I want to a function that will look in A1 and see if any words in that cell match any cells in B1.



=if("any words in A1"="anywords in B1","similar","no-match")

Something along those lines
