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

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