Pls help...FTSearch and literal quote

How can I FTsearch for a string that contains a quote?

My java application needs to search for product desciptions like 2.5" S80 316L

Here is an actual search string I encountered.

NotesException: Notes error: Formula Error ((partnumb1=“2.5” S80 316L" | partnumb2=“2.5” S80 316L" | partnumb3=“2.5” S80 316L" | partnumb4=“2.5” S80 316L") & Vendor = “PEX” & (heatnumb1=“515624” | heatnumb2=“515624” | heatnumb3=“515624” | heatnumb4=“515624”))
