Perhaps you should try some spelling variations:
general topology » general morphology, general phonology
neural topology » natural topology, neural topologies, dual topology
1722 early » 1727 early
22 early » 2 early, 12 early, 1.2 early
20 early » 10 early, 1820 early, 1720 early

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: %((neural topology) OR (general topology)) %((((22 early) OR (1722 early))) OR (20 early)) works to 1800%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((neural topology) OR (general topology)) %((((22 early) or (1722 early))) or (20 early)) works to 1800%22".
• Adding a wildcard symbol may retrieve word variants: %((neural topology) OR (general topology)) %((((22 early) or (1722 early))) or (20 early)) works to 1800%22*.
