Hi Mark,
It would be great if you can make this change and send the
QueryTermsExtractor class. I am invoking the QueryScorer(Query)
contructor. Should I use QueryScorer(Query query, IndexReader reader,
String fieldName) instead for this to work?
Thanks,
Harini

The problem lies in the QueryTermsExtractor class
which is typically used to provide the Highlighter
with the list of strings to identify in the text. It
currently has no filter for fieldname - you could add
this without too much effort.
I could make this modification but it may change the
behaviour of existing applications - currently the
QueryTermsExtractor method that takes a fieldname only
uses that fieldname to derive IDF weightings, the
proposed change would also have the effect of
filtering out any query terms that weren't for this
field.
Would this change be a problem for anyone?
Cheers,
Mark

Hi,
I have a requirement to highlight search keywords in
the results and
display the matching fragment of the text with the
results. I am using
the Hits highlighting mentioned in Lucene in Action.
Here is the search query(BooleanQuery) I am passing
to the IndexSearcher
and QueryScorer:
+DocumentType:news
+(CompanyId:10 CompanyId:20 CompanyId:30
CompanyId:40)
+FilingDate:[20041201 TO 20051201]
+(Content:"cost saving" Content:"cost savings"
Content:outsource
Content:outsources Content:downsize
Content:downsizes
Content:restructuring Content:restructure)
My requirement is to highlight only the keywords for
'Content' field,
but the highlighter api is also highlighting words
like 'news', '10',
'40' etc.
Is there anyway to restrict the highlighter to
highlight only the values
mentioned for the field 'Content'?
Thanks,
Harini
