Bug Description
The new Statistically generated record ratings from bug 1549505 introduces two new ranking methods to the catalog.
The Most Popular ranking method first retrieves the records based on their popularity badge score. If several records in the result set have the same score, they are then retrieved in order of bib relevance.
The Popularity-Adjusted Relevance ranking method attempts to consider both bib relevance and popularity badge scores in the sort order. There is a global flag that gives you some control over the weight popularity badge scores receive in this ranking method. When using this sort method, even if the global flag weight is fairly low, popular materials will still float high in the list, but if there is a record that scores high on bib relevance, it may appear before those popular results.
Both sort methods have value, and different Evergreen sites may opt to use different sort methods. However, including both sort methods in the dropdown will be confusing to users, who are unlikely to understand the fine differences between each sorting method. We should choose to one of these methods to display in the sort dropdown by default, while making the other available to those sites that prefer to use the other.
After extensive testing on our part, MassLNC recommends going with the popularity-adjusted relevance sort option as the default. It's imperfect, and we would like to see it improved in the future, but we think it's the one that will be the most likely to retrieve good results for the user, particularly for general keyword searches.
I can create a branch to do so if we have a consensus that this is the best direction to go.
