Perhaps you should try some spelling variations:
"The complex services" » "The complex service", "The composed services", "The complex surfaces"
"The complex series" » "The complex queries", "The complete series", "The compleat series"
"the compass series" » "the compass varies", "the comparison series", "the compass exercises"

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