Hello, I'm having trouble understanding the relationship of the word "tie" and "tiebreaker" to the explanation of this parameter on the wiki. What two (or more things) are in a tie? and how does the number in the range from 0 to 1 break the tie?
http://wiki.apache.org/solr/DisMaxQParserPlugin#tie_.28Tie_breaker.29 "A value of "0.0" makes the query a pure "disjunction max query" -- only the maximum scoring sub query contributes to the final score. A value of "1.0" makes the query a pure "disjunction sum query" where it doesn't matter what the maximum scoring sub query is, the final score is the sum of the sub scores. Typically a low value (ie: 0.1) is useful." Tom Burton-West
