Hi Jose,
Your code likely would still work, but it may be easier to simply enable
the "search" index event consumer (this is the one that refreshes a
Lucene index).
By default, 5.x has this list of event consumers enabled in dspace.cfg:
event.dispatcher.default.consumers = versioning, discovery, eperson,
harvester
The "discovery" consumer ensures Discovery (Solr) reindexes when changes
occur. You could just append the "search" consumer to similarly notify
Lucene, e.g.
event.dispatcher.default.consumers = versioning, discovery, eperson,
harvester, search
Adding "search" to that list triggers this SearchConsumer whenever
changes to Community, Collection & Items occur (including when
filter-media runs)

Thanks Tim for your response. What I have done is I have left the
advance page from previous Dspace instances with Lucene, but
everything else is Discovery. This page uses lucene:
https://deepblue.lib.umich.edu/advanced-search
and so does the box on the menu bar from the main page:
https://deepblue.lib.umich.edu/
So I'm using some old code to get this functionality.
Now, in the past I had the code from my previous email in the
filter-media so that the full text search for the lucene index would
be updated. When I did the last code merge I chopped that code out,
and am now realizing that I need to put it back in if I the lucene
full text search to work. What do you think?
Thanks again!
Jose

Hi Jose,
Could you describe your setup more? It's not actually possible
(well not recommended) to run Discovery (which uses Apache Solr)
AND Lucene (which is a separate search interface) simultaneously.
Are you running Discovery, or are you running the traditional
Lucene-based search? By default, DSpace 5.x uses Discovery.
https://wiki.duraspace.org/display/DSDOC5x/Discovery
If you are running Discovery, then it is notified of any updates
to items, etc. and will reindex individual items when notified.
There's no need to add any special code for that.
If you are still using Lucene, you might want to think about
whether it's worth moving to just using Discovery. In 5.x, we
deprecated Lucene searching, and it is being removed entirely in
6.x (coming soon). So, while you can still use Lucene in 5.x,
you'll eventually need to move to using Discovery (with Solr) once
6.x is released.

I am currently using lucene and discovery in 5.1. In 4.2 I had
this bit of code in MediaFilterManager.java so that when ./dsapce
filter-media ran the lucene index would be updated. I wonder if
it will work in 5.1 and if perhaps there is a better way to do
it. This is the code I had:
if (updateIndex)
{
if (!isQuiet)
{
System.out.println("Updating search index:");
}
DSIndexer.setBatchProcessingMode(true);
try
{
DSIndexer.updateIndex(c);
}
finally
{
DSIndexer.setBatchProcessingMode(false);
}
}
Thank you!
Jose
