Hi Andy, Why do you want to group by title? It seems to contain the brand and product number, right?
Also from what I understand from your email the field title is analysed. Grouping on fields that are analysed give unexpected results. Grouping is usually performed on fields that are of type string. You can configure new field named title_str (example) and use a copyField that provides the title_str with content from the title field. The groups are then formed based on the complete value from a field (e.g. 吸尘器（Panasonic） MC-CA391G). Obviously you then need to group by title_str field. If you don't want to group by title, but something else e.g brand then you need to put this in a new field (that doesn't analyse text) and group by that field.
