Hi,
Is it possible to refresh the stop word list periodically say once in 6
hours. Is this already supported in Solr or are there any work arounds.
Kindly help me in understanding this.

Hi,

you can trigger a reload command to the core admin, assuming you're
running a multi core environment (which I'd recommend anyway).

Simply add
"curl http://host:port/solr/admin/cores?action=RELOAD&core=corename"
to your /etc/crontab file, and set the leading time fields correspondingly.

-Kuli

Of course, if you change stop words you may want to reindex your old content, so that the new state of stop words is reflected in all documents.
It's not an absolute must to do that, but if you do not do it, you may see strange search results that will make you wonder why some documents matched a query when they look like they should not have matched, and vice versa.

I am not running in a multi core environment. My application requires only a
single search schema. Does it make sense to go for a multi core setup in
this scenario? Given that we currently have a single core is there any
alternative to RELOAD which work in a single core setup?

You could restart your Solr instance.  If you have just 1 Solr instance, that means a bit of a downtime.  If you have 2 Solr slaves behind a Load Balancer, then you can avoid that downtime.
But I think you could also just configure your 1 Solr core via solr.xml and then you can use that RELOAD command.

In recent versions of Solr (I think since 3.1) every Solr installation is
a multi-core environemnet, Solr just silently uses a hardcoded default
solr.xml that uses the solr home dir as the instanceDir of the "default
core" if your solr home dir doesn't already contain a solr.xml.

So even if a single core setup, you should still be able to reload the
core.
-Hoss

What will be the name of this hard coded core? I was re arranging my
directory structure adding a separate directory for code. And it does work
with a single core.

In trunk the "single core setup" core is called "collection1". So to
reload that you'd call url:
http://localhost:8983/solr/admin/cores?action=RELOAD&core=collection1

Thanks Sami. I ended up setting up a proper core as per documentation,
named core0.
