By default, if the search query matches tokens inside another result, the line will be displayed twice. For example, this CQL "J.*"{1,3}"N.*"(default attribute: tag) finds a noun preceded by 1, 2 or 3 adjectives and it will find little black dress but also black dress. Both results will be included in the concordance even though one is found inside the other. Hide sub-hits will only display the longer result: little black dress.
