Subject Re: Realtime Search for Social Networks Collaboration
Date Sat, 06 Sep 2008 20:04:01 GMT
Hello Shalin,

When I tried to integrate before it seemed fairly simple.  However the
Ocean core code wasn't quite up to par yet so that needed work.  It
will help to work with SOLR people directly who can figure how they
want to integrate such as yourself.  Right now I'm finishing up the
OceanDatabase portion (sorry for all the Ocean names and things, these
can be changed, doesn't matter, but it should be something we agree
on).  The methods to TransactionSystem are like IndexWriter.  The
update method for OceanDatabase is perform(Action action).  There are
3 actions, Insert, Update, Delete.  To execute queries the whole thing
is abstracted out as a Task.  The method is Object run(Task task).
Where task gets a reference to the TransactionSytem. I implemented a
MultiThreadSearchTask that as the name suggests, executes a query in
multiple threads over the latest Snapshot.  The reason for the Task
abstraction is to give the client complete access to the server via a
potentially dynamically loaded subclass of Task.  OceanDatabase should
be the main class for most uses of the realtime system because it
implements optimistic concurrency.  I prefer the simplicity of the
main entry point into the search server being only two methods, with
the run method offering unlimited functionality without recompiling,
building and deploying the server for each new piece of functionality
required.

Regards,
Jason
