You can add "Rules" that will reduce the List:The "has" rule which says that certain items must be included (for the entry to be included).
Example: has 2,a,b,c means that an entry must have at least two of the letters a, b and c.
The "no" rule which means that some items from the list must not occur together.
Example: no 2,a,b,c means that an entry must not have two or more of the letters a, b and c.
The "pattern" rule is used to impose some kind of pattern to each entry.
Example: pattern c,* means that the letter c must be first (anything else can follow)
Put the rule on its own line:
Example: the "has" rule
a,b,c,d,e,f,g
has 2,a,b
Combinations of a,b,c,d,e,f,g that have at least 2 of a,b or c
