Combining minimum match and search term associations
There are two ways that you can use enable minimum match with search term associations: Solr synonym expansion algorithm, or the query-time expansion algorithm. You cannot use the default search algorithm provided by WebSphere Commerce to combine minimum match with search term associations.
The default search algorithm provided by WebSphere Commerce expands the original search term before passing it into Solr. Minimum match is applied to the expanded search terms. For example, if teacup, mug and cup and defined as synonyms and minimum match is set to 2; then a single word query for cup will not produce any search results. The expanded search term consists of teacup, mug and cup. Since no single product has cup and mug indexed together, the minimum match requirement is not satisfied and no results are returned.
