Re: [Dspace-tech] What's the plan for "Browse by" functionality?

2015-06-13 Thread Alan Orth 
That's good to hear, Tim. I was mistaken about "Browse by" still using
Lucene. Recently I found some metadata out of date on our DSpace instance,
and it turns out I had to re-activate the Lucene indexing cron jobs which I
had disabled after upgrading to DSpace 4.x last year. But actually this was
for one of our third-party modules, not "Browse by".

Now to pressure the developer of the third-party module to update to
Discovery. ;)

Regards,

Alan

Hi Alan,

In recent versions of DSpace (4.x and above), Discovery does *both* 
Browse and Search. So, those "Browse By" options are now handled by 
Discovery. These days, if you install DSpace will default options, 
Lucene is not used at all, and everything runs through Discovery (with 
Apache Solr) behind it.

The plan going forward is that Discovery will be the search/browse 
system. The old Lucene / DB-based search and browse system is deprecated 
and will be removed in the near future.

[Dspace-tech] What's the plan for "Browse by" functionality?

2015-06-10 Thread Alan Orth 
Hi,

Discovery's great but "Browse by" does some things that we like, such as
being able to paginate the results (compare browse[0] with discovery[1])!

The problem is that "Browse by" is terrible because it still uses Lucene,
which means we have to maintain parallel lists of indexes for both Lucene
and Discovery, and Lucene is a systems admin nightmare because you have to
shut down Tomcat for 15 or 20 minutes while you init the indexes after
adding new metadata!

I guess I'm curious what the long-term plan is for the "Browse by"
functionality in DSpace?

Thanks,
