DBSight, a J2EE search engine on database, meets most of your requirements.
It has clustering support. Basically you can configure one DBSight
server specially for indexing on database content. Another or several
other DBSight servers devoted to search, and they subscribe to the
indexing server
Hello:
I have yet another file-system related error, if I set the boolean
create to true on idex writer, I have no problems (other than never
getting more than one hit, because I create and close the idnexwriter
in one method to assure the class is the only instance)
However, if I set it to false,
Hi,
I haven't heard anything back. Probably this email got lost on the way
or whatsoever.
Anyway, could anyone enlighten me on this?
Thanks,

Subject: when is the commit.lock released?
Simply storing a parentId doesn't help query the hierarchy though -
for example, search for all "lucene" containing documents in a
specific forum thread, children and all.
One technique I've used to index hierarchy is to come up with a path
string such as "/parent/child/grandchild" and inde
I have two ideas:
1. wildcard query on the path field, but this only works if you have a
small number of elements in any path hierarchy.
2. store each path component as a separate "term"
a. for instance: /people/tony/property yields the following terms:
path:/people and path:/people/ton
Ross - could you please show us a bit of your code so we can see
explicitly what you're doing and how it's not working as expected?
set/getPhraseSlop are quite straightforward, so unless you're mixing
up the static versus instance parse methods with QueryParser then I
don't know what could
Hi,
Recently I looked at the locking mechanism of Lucene. If I am correct,
I think the process for grabbing the lock file will time out by
default in 10 seconds. When the process timed out, it will print out
the IOException.
The lucene locking mechanism is not within threads in the same JVM. It

Wouldn't the parameter boolean create false create the segments if it

creates or doesn't the actual directory on startup...does this affect
key files as well?

that...Just wondering what's up?

Hi
I've indexed my website from the application root. When I run a query, it
beasically searches all content below the application root folder.
I would like to create feature that would allow users to search specific
folder/paths of this website. (i.e I would like to limit my query search to
When I'm using the QueryParser directly, the proximity search works fine and
getPhraseSlop() returns the correct slop int.
The problem is when I extend QueryParser. When extending it, getPhraseSlop
always returns the default value - 0. It's like setPhraseSlop is never
called.
Does anybody know if
You could have a parentId field in each document - which will give you a
nice hierarchy. You could also create a topicId (Linux, Microsoft,
etc...) and a storyId. At that point you can quickly identify the topic
and story for the message - and you can also search within a specific
thread (AND

Hi,
Perhaps using hprof with cpu=samples may reveal more information about

Considerations that you may want to think about when sanitizing your
clustered indecies:
1) Number of documents available vs. number of documents in the
persistent store.
2) Are all the document up to date (involves comparing the existence and
