Description

When you use FastVectorHighlighter fragments returned have the match at the beginning. In most situation it is much more useful to create fragments with the match in the middle. I've included a really trivial patch to enable this with a specialized constructor of the SimpleFragListBuilder

Es: FastVectorHighlighter hilighter = new FastVectorHighlighter(true, true, new SimpleFragListBuilder(true), new SimpleFragmentsBuilder());

The true parameter to SimpleFragListBuilder is named matchInTheMiddle so it has a descriptive name. Probably it would be useful to create an enum to place the match at: beginning, middle, end.
