I don't have any best practices to offer. I have been using Lucene with MySQL for an
year though.
All I do is store a key of some sort in the index
new Field(id, getPK(), true, false, false)
and then relate that to the database in code.
For Live Oracle databases, you might consider different
Hi again,
I'm thinking to get the list of IDs from the database and the list of
hits from Lucene Index and to create a comparator in order to eliminate the
not permitted Hits from the list.
Which solution do you think is better?
Thanks,

Hey Guy's
Apologies.
I have a Question
Is there any API avaliable in Lucene1.4 to set the Score value to 1.0f or

BEFORE doing the Query Parser for search , so that the returns Hits for
the Score settings only.

In this situation, you may want to investigate implementing a custom
Filter which is user-specific and constrains the search space to only
the rows a specific user is allowed to search.

Kathik,
I have a really hard time following your questions, otherwise I'd chime
in on them more often. Your meaning is not often clear.
In the case of normalizing the score to 1.0 or less - this is precisely
what Hits does for you. I'm not sure what you mean by BEFORE doing
QueryParser - a
I don't really understand what QueryParser has to do with your
question. If you want only Hits that have a score of 1.0 (keep in mind
that Hits normalizes scores if they are over 1.0), why not just walk
all the Hits in order until you get to one that is not 1.0?
Or, use a HitCollector to
If you know ahead of time which documents are viewable by a certain user
group you could add a field, such as group, and then when you index the
document you put the names of the user groups that are allowed to view that
document. Then your query tool can append, for example AND
group:developers
If its a web application, you have to cal request.setEncoding(UTF-8)
before reading any parameters. Also make sure html page encoding is
specified as UTF-8 in the metatag. most web app servers decode the request
paramaters in the system's default encoding algorithm. If u call above
method, I think
This is not a solution in my case,
becasue the permissions of the groups, and the user groups can be
changed, and it will make managing index to be a nightmare.
anyway,
I appreciate the advice, maybe it will be useful for the other guys
that asked this question.

I wanted to support categories, and so I created my own analyzer so that:
Root Category||My Category||Some Other Things
Would be split up into three terms split by ||, and I wanted it to stay
case sensitive.
If I do a search for:
categories:Root Category
it works fine. But if I do a search for:
Don, I think I finally understand your problem -- and mine -- with
MultiSearcher. I had tested an implementation of my system using
ParallelMultiSearcher to split a huge index over many computers.
I was very impressed by the results on my test data, but alarmed
after a trial with live data :)

I don't think I understand correctly your proposal.
As a basis, I am using Demo3 with indexHTML, HTMLDocument and HTMLParser.
Inside HTML parser, I am calling getMetaTags (calling addMetaData) wich
return Properties object. My issue is coming fron this definition :

Hello,
When indexing a field, we have the choice of tokenizing it or not. I
have a custom analyzer that contains a tokenizer... does it mean that
if the boolean token is set to false, the analyzer is not applied on
the field content?
Everywhere in the documentation (and it seems logical) you say

Imperfectly.
The QueryParser knows nothing about the index, so it does not know which
fields were tokenized and

any other suggestions?
