Sorry for the interruption, This error was due to wrong context path mentioned
in solr-jetty-context.xml
And in jetty.xml it was referring /solr. So index was locked.

Hi Shawn,
I did delete the data folder of the core and also did in windows command: solr
stop -all. I see only one solr server is running in this machine which gets
started and stopped when I do so. To confirm, I even copied my folders to
another system and tried there but facing same issue.

I want to use the Solr query elevation component. Let's say I want to

Hi,
Could anyone let me know if a real time get would return a cached, up to date
version of a document if we enabled documentCache?
Thanks

Hello,
Is there a way to block certain queries in solr? For eg a delete for *:* or
if there is a known query that causes problems, can these be blocked at the
solr server layer.

Hey all,
When our searcher refreshes on a soft-commit, we get a slight latency spike
(p99th response times can jump up to about 200ms from 100ms), however what we
see in the upstream clients using org.apache.solr.client.solrj SolrClient is a
big spike in connections outbound (70-80 per client,

This is a bit of a guess - I haven't used this functionality before.
But to a novice the "tag" Rule Condition for "Rule Based Replica
Placement" sounds similar to the requirements you mentioned above.

Yup, I find the right calculation to be as much ram as the server can take,
and as much SSD space as it will hold, when you run out, buy another server
and repeat. machines/ram/SSD's are cheap. just get as much as you can.

But if you must have a number, assume that the index will be as big as your
(text) data. It might be 2X bigger or 2X smaller. Or 3X or 4X, but that is a
starting point. Once you start updating, the index might get as much as 2X
bigger before merges.

Hello,
Looking to see how others accomplished this goal. We have a 3 Tier

Auto-Suggest calls from the Internet Browser through the Tiers down to Solr in
T3? We essentially created steps down each tier, but I'm

Otherwise, I typically go with

Now I have a simple question, How do I know my index size? A simple method,

My assumption so far is the total
