Perhaps you should try some spelling variations:
income distributions » income redistribution, time distributions, discrete distributions
genome distribution » genomic distribution, gene distribution, monomer distribution
turf developing » stuff developing, future developing, tariff developing

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: %((genome distribution) OR (((income distributions) OR (income distribution)))) %turf developing countries%22.
• Adding a wildcard symbol may retrieve word variants: %((genome distribution) or (((income distributions) or (income distribution)))) %turf developing countries%22*.
