Hi,
I am using the downloaded weblucene. I have started my tomcat server and trying
to search by clicking on the search button but it says the search page cannot be
found. Also, I cannot find it in the package.
Can anyone help?
Am I missing anything?

You would just take the items from mysql database and create a document for each
record. Then index all the documents.

Hi.
You read out all the relevant fields from MySQL and assign the primary key
as an indentifier of your Lucene "documents".
During search, you retrieve the identifier from the Lucene searcher and
query the database to present the full text.

Maurits: thanks for the hint to classifier4j -- I have had a look on this
package and tried the SimpleSummarizer and it seems to work fine. (However,
as I don't know the benchmarks for summarization, I'm not the one to judge.)
Do you have experience with it?

Yes, copying a summary from one field to an untokenized field was the plan.
I identified DocumentWriter.invertDocument() to be a possible place for an
addition of this document-level analysis. But I admit this appears way too
low-level and inflexible for the overall design.
So I'll make it "two-p

Is there any tutorial how to implement this kind of search feature.

Hello Gregor and Maurits,
I am not quite sure what you want to do. I think you want to search the
normal text and present the summarized text on the screen where the user is able
to get the full text on request. Is this the case?
If this is the case, then you could create a set of summarized text
Is there any way to get a TokenStream for a given Field of a Document (is that
information even stored in the index)? I want to use the startOffset / endOffset
information for hit highlighting. Do I have to tokenize the text value for the field
again to get this information?
Also, as has been mentioned before, you might not need to
boost the title. Since titles tend to be shorter than the actual
document terms in the title are given more weight than terms in the
document.

If you wish to boost the title field for every query then it would be
easiest to boost the title clause of your query, with Query.setBoost().
Field.setBoost() should only be used when you want to give a field
different boosts in different documents, but since you want to boost all
titles by th
It sounds like you want the value of a stored field (a summary) to be
built from the tokens of another field of the same document. Is that
right? This is not presently possible without tokenizing the field
twice, once to produce its summary and once again when indexing.

The WhitespaceTokenizer fixed the problem, so that'll do as a stop gap until
I can figure out how to write our own COBOL tokenizer.
