Hi James,
Try this:
Searcher searcher = new IndexSearcher(dir);
QueryParser parser = new QueryParser("content", new StandardAnalyzer());
Query query = parser.parse(queryString);
HashSet queryTerms = new HashSet();
query.extractTerms(queryTerms);
Hits hits = searcher.sear
Hi
Is it possible to Hightlight more than one terms with highlighter but
with different style for each term ??
1st term with SimpleHTMLFormatter("", "");
2rd term with SimpleHTMLFormatter("", "");
..
n-th term with SimpleHTMLFormatter("", "");
or for foloween code

Hi John,
Just continuing from an earlier question where I asked you how to handle
strings like "from:fred flintston*" (sorry I have lost the original email).
You advised me to write my own BooleanQuery and add to it Prefix- /
Term- / Phrase- Querys as appropriate. I have done so, but am having
Hi,
I want to modify a field on the current index. Can it be done?
For what I have heard that we cannot update the index . It has to be
reindexed by deleting and then indexing again.
Thanks,
Aditi
Hi John,
Further to my question below, I did some back-to-basics investigation of
PhraseQueries and found that even basic ones fail for me...
I found the attached code on the Internet (see
http://affy.blogspot.com/2003/04/codebit-examples-for-all-of-lucenes.html)
and this fails too... Can you
Yes you must delete the entire document and then re-index a new one,
to update a single Field.
There is some work underway, or at least a Jira issue opened, towards
improving this situation, here:
https://issues.apache.org/jira/browse/LUCENE-1231
But it will be some time before that'
Yes, the term frequency vector is exactly what I needed. Thanks!

Hi.
Currently using Lucene 2.3.2 in a tomcat webapp. We have an action
configured that performs reindexing on our staging server. However, our live
server can not reindex since it does not have the necessary dtd files to
process the xml.
To update the index on the live server we perform a subvers

You might want to switch instead to rsync.
A Lucene index is fundamentally write once, so, syncing changes over

Currently the default setting is being used with our setup, so

Hi John,
Please ignore my earlier questions on this subject, as I have got to the
bottom of it.
I was not passing each word in the phrase as a separate Term to the
query; instead I was passing the whole string (doh!).
Thanks.

Hi John,
In case of deletions, it is just a delayed delete. In other words, the doc
is just marked as deleted in the deletable file, leaving a void in the
numbering of docs. The actual shifting of document ids happens only when you
optimize the index. In that case the deletables file is used to ph
