If you are trying to use Boolean operators, they must be ALL CAPS: (("operator theory") OR ((("operation theory") OR ((("observations theory") OR ((("observations thereon") OR ("observations therein")))))))).
The words AND, OR and NOT may confuse the search; try adding quotes: "((\"operator theory\") or (((\"operation theory\") or (((\"observations theory\") or (((\"observations thereon\") OR (\"observations therein\"))))))))".
Removing quotes may allow a broader search: (( operator theory ) or ((( operation theory ) or ((( observations theory ) or ((( observations thereon ) OR ( observations therein )))))))).
Adding a wildcard symbol may retrieve word variants: (("operator theory") or ((("operation theory") or ((("observations theory") or ((("observations thereon") OR ("observations therein"))))))))*.
