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:
I have a body of text which is being added to a document as unstored. All
the words in the body text are coming through in the token stream for
analyzing. For some reason I can search on some of tokens and others I can
not.
Take the following string:
L'amministrazione di Uniface View consente
Is there anyway to restrict the highlighter to
highlight only the values
mentioned for the field 'Content'?
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
What Analyzer are you using? Have a look at the Analyzer demo with
Lucene in Action's code, or from my java.net article so you can
analyze your analyzer. Also try out Luke, it really is handy for
seeing inside your index.
And is your text really long ( 10,000 terms)? If so, you'll
Hi,
I am working for a major Application Service Provider in Europe and we

are overall very pleased with it but as the load on the application
which uses Lucene increased we were forced to invest in better hardware
and also
I wrote my own analyzer: When I view the tokens returned from the
StemFilter the words I'm searching for are returned from the Token Next()
function. My terms are under 10,000. I have used luke before how can I make
it use a custom analyzer? Thank you for the information.

Have any one implemented LSI in Lucene?
Kindly let me know how hard/easy it is.

It depends on the kind of implementation you are thinking of.
You can use Lucene to create the inputs to the LSI, and then use them in
your own system. I've written that code and it works, for searches and
clustering.
But if you are figuring out an LSI enhanced Lucene search system (based on a

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

I don't know what your application is, and I have no experience with the
Highlighter code, so forgive me if this is a silly suggestion:
It looks like you are building a query up programaticaly, which
contains some words to search on, and some other stuff that's mainly
