The attachment didn't make it through here. Can you add it as an attachment to
a new JIRA issue?
Thanks,

If you can supply a Junit test that recreates the problem I think we can start
to make progress on this.

Hi
Apologies for re sending this mail. Just wondering if anyone has experienced
the below.. I'm not sure if this could happen due nature of document. It does
seem strange one term search returns summary while another does not even though
same document is being returned.
I'm asking this so I can code around this if is normal.
Apologies again for re sending this mail
Cheers

Hi
I am seeing some strange behaviour with the highlighter and I'm wondering if
anyone else is experiencing this. In certain instances I don't get a summary
being generated. I perform the search and the search returns the correct
document. I can see that the lucene document contains the text in the field.
However after doing:
SimpleHTMLFormatter simpleHTMLFormatter = new SimpleHTMLFormatter("<span
class=\"highlight\"><b>", "</b></span>");
//required for highlighting
Query query2 = multiSearcher.rewrite(query);
Highlighter highlighter = new Highlighter(simpleHTMLFormatter, new
QueryScorer(query2));
...
String text= doc.get(FieldNameEnum.BODY.getDescription());
TokenStream tokenStream =
analyzer.tokenStream(FieldNameEnum.BODY.getDescription(), new
StringReader(text));
String result = highlighter.getBestFragments(tokenStream, text,
3, "...");
the string result is empty. This is very strange, if i try a different term
that exists in the document then I get a summary. For example I have a word
document that contains the term "document" and "aspectj". If I search for
"document" I get the correct document but no highlighted summary. However if I
search using "aspectj" I get the same doucment with highlighted summary.
Just to mentioned I do rewrite the original query before performing the
highlighting.
I'm not sure what i'm missing here. Any help would be appreciated.
Cheers
Amin

No just use Field.Store.COMPRESS when adding to index and Document.get()
when fetching. The decompression is automatically done.
You may think, why not enable compression for all fields? The case is, that
this is an overhead for very small and short fields. So you should only use
it for large contents (it's the same like compressing very small files as
ZIP/GZIP: These files mostly get larger than without compression).
