Perhaps you should try some spelling variations:
"10 stages stages" » "10 states stages", "10 ages stages", "10 sales stages", "10 stage stages", "20 stages stages"
"10 steps series" » "10 step series", "10 steps seem", "10 steps stages"
"10 stages stage" » "10 stage stage", "20 stages stage", "10 states stage"

Try widening your search to All Fields.

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: (("10 steps series") OR ((("10 stages stages") OR ("10 stages stage")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"10 steps series\") or (((\"10 stages stages\") OR (\"10 stages stage\"))))".
• Removing quotes may allow a broader search: (( 10 steps series ) or ((( 10 stages stages ) OR ( 10 stages stage )))).
• Adding a wildcard symbol may retrieve word variants: (("10 steps series") or ((("10 stages stages") OR ("10 stages stage"))))*.
