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).
