Perhaps you should try some spelling variations:
heats » heat, heads, heath
cheats » cheat, cheads, cheath, cheaps, wheats, chats
cheat » cheap, wheat, chat
cheath » cheaph, wheath, chath, heath, sheath, creath
cheads » heads, aheads, chears
cheaph » cheap, cheape, cheah

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: "((heats OR cheats) OR ((cheat OR cheads) OR (cheath OR cheaph))) of mixing AND (solution" or solutions").
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((heats or cheats) or ((cheat or cheads) or (cheath OR cheaph))) of mixing and (solution\" or solutions\")".
• Removing quotes may allow a broader search: ((heats or cheats) or ((cheat or cheads) or (cheath OR cheaph))) of mixing and (solution or solutions ).
• Adding a wildcard symbol may retrieve word variants: "((heats or cheats) or ((cheat or cheads) or (cheath OR cheaph))) of mixing and (solution" or solutions")*.
