Perhaps you should try some spelling variations:
"computer software—redisability" » "computer software—revisability", "computer software—creditability", "computer software—predicability"
"computer software—realisability" » "computer software—realizability", "computer software—reachability", "computer software—readability"

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: (((("computer software—redisability") OR ("computer software—realisability"))) OR ((("computer software—usability") OR ("computer software—disability")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"computer software—redisability\") OR (\"computer software—realisability\"))) or (((\"computer software—usability\") or (\"computer software—disability\"))))".
• Removing quotes may allow a broader search: (((( computer software—redisability ) OR ( computer software—realisability ))) or ((( computer software—usability ) or ( computer software—disability )))).
• Adding a wildcard symbol may retrieve word variants: (((("computer software—redisability") OR ("computer software—realisability"))) or ((("computer software—usability") or ("computer software—disability"))))*.
