Perhaps you should try some spelling variations:
"abel cano" » "el cano", "abell cano", "abeli cano", "abiel cano"
"abel caso" » "el caso", "al caso", "del caso", "abell caso", "abeli caso", "abiel caso"
"bel cuando" » "bell cuando", "beli cuando", "biel cuando"
"abel canto" » "abell canto", "abeli canto", "abiel canto"
"abel cabo" » "abell cabo", "abeli cabo", "abiel cabo"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"bel cuando\") OR (((((\"abel canto\") OR (((\"abel cano\") OR (\"abel cabo\"))))) OR (\"abel caso\"))))~".
• Removing quotes may allow a broader search: (( bel cuando ) OR ((((( abel canto ) OR ((( abel cano ) OR ( abel cabo ))))) OR ( abel caso ))))~.
• Adding a wildcard symbol may retrieve word variants: (("bel cuando") OR ((((("abel canto") OR ((("abel cano") OR ("abel cabo"))))) OR ("abel caso"))))*.
