Subject Re: Development plans for Lucene?
Date Wed, 30 Oct 2002 19:33:32 GMT
Otis, Kelvin and me have been discussing how we could leverage Lucene on a
next level. We have some components in the sandbox (LARM Webcrawler, Indyo
indexing framework) that have to be weaved together with Lucene.

This could end up in a real search engine server. I call it "Lucene Advanced
Retrieval Machine" for myself right now, 'cause then I can stick with the
LARM acronym... :-)

This will be a server that gets data from somewhere (i.e. the Web or the
file system), does processing steps on it (i.e. extracting text from HTML or
PDF) and puts the results into a Lucene index. The whole process forms an
assembly line, with data sources at the beginning and a storage at the end.
A source is an active component that decides when to put a URL or a document
into the queue (i.e. because there's a notification if the doc has changed,
if the stored doc is obsolete, or if a recrawl is said to be necessary).

This assembly line can also be broken up (in serial or in parallel) such
that different steps of it can be executed on more than one machine. As
such, the storage could be a JMS queue (or even a topic) that is filled in
batch mode. On the other side, the JMS then is the data source.

There are lots of construction sites, though. The architecture must be solid
and efficient. The crawler has to be made more scalable. We're also
discussing on how we can save time implementing server related stuff and
configuration - taking the Avalon framework is (probably a good) option, but
no one of us has used it before.
