question

1. If multiple rules are configured, do multiple rules need to be satisfied at the same time, and how does the weight work?

Yes, multiple rules need to be satisfied at the same time. Weight is a way to modify the importance of a rule. Rules in general provide both a restriction as well as a way to sort the remaining tickets that are eligible. The weight is a multiplier, modifying how important the rule is for sorting purposes.

2. The description of each matching rule seems confusing, such as

- Team ticket size similarity rule: Does it mean that only matching ticket sizes are equal?

Team ticket size similarity rule ensures that all teams either have a large party, or do not have a large party. A large party is defined as at least half of the maximum team's size.

- Team difference rule: What is the difference quantity? Is the size of the list difference set aggregated for the specified field in different teams?

Team difference rule ensures that teams included in a match are within a configured difference for a specific attribute (such as skills). This is very similar to a standard Difference Rule, except that the values compared are each team's average value.
