Hi Anjo,
I should qualify that I'm not using ERIndexing but my own homegrown
version of a Lucene index. In my solution I have EOs that update
their index when their state transition changes i.e.
awakeFromInsertion, didDelete etc...
After reading your post I became nervous that I might ha
The changes go into two queues, so there is no telling which order
they get in two different instances.
Cheers, Anjo

Hi Anjo,
I kind of understand what you are saying but I have a couple of
questions.
Wouldn't p1 and p2 have to be editing the same EO for the index to
become out of sync with the database?
If you have two users editing the same EO wouldn't the normal WO
mechanisms resolve the issue?

FWIW, I've used the OpenBase Lucene stored procedures in an app, and
been quite happy with the results.

We do what David is describing, but how about this:
- one instance makes the changes and updates to the lucene index
- many instances may make changes to the databases, but use change
notification to propagate updates, by doing so the lucene instance
makes the appropriate updates to the luce

Don't give up hope! The severe drawbacks that Anjo describes are
worth solving, in my opinion. It isn't just about fast searching, it
is about the incredible flexibility that Lucene provides. Resolving
easily to EO is a big benefit too.

Be aware that ERIndexing is only an experiment (and was write-only
code, I don't use it yet). In particular it has several severe
drawbacks:
- it doesn't really handle multiple instances (possibly) or servers
(definitely). That means, for the cases where you actually *do* need

ERXApplication.main(argv, Application.class); in main )

Hi Gustavo,
I run this in my application startup. Do you have an indexModel file
in your Resource folder? This file is used by ERAutoIndex to specify
the entities and attributes to index.

if not i'll start poking around the code.

Hello All.
What would be the best way to implement this, I mean, the server where Im

So I was thininking to surround the textefield where the user can type with

Well I don't need to be 100% exact, but let's say an 80%, Im looking at

will take a look at also.
if I understood good, these algorigthms chech the strings and return a

The most performant method is (most likely) achieved by using the
