I see it as a feature, not a bug. The appearance of stop words in the Search
Summary makes it more clear what the Hit is about.Not sure but I think Google
does the same in search summaries.-Evert(http://www.ejwagenaar.com)

java-user@lucene.apache.org Subject: Re: [External] Re: How to ignore certain
words based on query specifics I just tested this with the
search.highight.Highlighter class.Is this the 'old default highlighter'?I
phrased my question badly.Of course the stop words shouldn't be highlighted,as
they wouldn't match any query.My question was really, would the stop words be
available forinclusion in the highlight context (surrounding a match)?The
answer is yes the stop words do appear in the context,and are not
highlighted.Thanks,David Shifflett On 7/10/19, 9:12 PM, "Michael Sokolov"

to be. I think some of them work using postings, and for those, no, you
wouldn't be able to highlight stop words. But maybe you can use the old
default highlighter that would reanalyze the document from a stored field,
using an Analyzer that doesn't remove stop words? Sorry I'm not sure if that
exists any more, maybe someone else will know. On Tue, Jul 9, 2019,
