This only affects requests with depth>1. If you execute such requests and
rely on the facet results being returned flat (i.e. no hierarchy), you should

+* LUCENE-1822: Improves the text window selection by recalculating the starting margin
+ once all phrases in the fragment have been identified in FastVectorHighlighter. This
+ way if a single word is matched in a fragment, it will appear in the middle of the highlight,
+ instead of 6 characters from the beginning. This way one can also guarantee that
+ the entirety of short texts are represented in a fragment by specifying a large
+ enough fragCharSize.
