Performance improvement in latest version comparing to v1.4
Hi all,
Currently we are using solr for service meta data indexing and Searching .
we have embedded solr server running in our application and we are using
solr 1.4 version. Have some doubts to be clear.
1. What are the performance improvements we can gain from updating to the
latest solr version(4.10.1).
2. Currently we are using embedded solr, I have an idea of moving to
standalone server. What is best way of using standalone server in our java
webapp.
Please help me.

My guess is that you don't have a default collection anymore. Maybe
you are using new collection autodiscovery mechanism and your
collection is not named collection1 (default name). So, you just need
to change your URL to include your connection name.

Thanks Alex and Shawn,
Yes, I have given the wrong URL. I have change the default name and I am
not specified that in the URL.
Issue resolved after correcting the URL
many thanks

I've never seen that exact error, but I suspect that it's happening
because you've provided an incorrect URL to the HttpSolrServer
constructor. It should look like the following:
http://server:port/solr/corename
A fully fleshed out example with an IP address instead of a DNS name:
http://10.1.1.54:8983/solr/collection1
If you've provided a URL with a # character in it, that is a URL for the
admin UI, which will only work correctly in a browser. I think we might
want to check for that in Solr code and give the user a meaningful
message in the exception, which will get propagated to SolrJ.
Thanks,
Shawn

Thanks for quick response Shawn.
I upgrade to the server and create new HttpSolrServer. when I try to add
document to the solr server, I am getting following error.

One of the key areas that's better/faster is indexing, but there are
performance improvements for querying too. Solr and Lucene have evolved
considerably in the four years since Solr 1.4 (using Lucene 2.9)
was released.

The embedded server is still available, although even in 1.4 it was not
recommended for anything but a proof of concept. You should simply
install one or more standalone servers and access them from your app via
http. On a LAN, the overhead introduced by http is minimal.
Since you're already using the embedded server, that's simply a
matter of changing EmbeddedSolrServer to HttpSolrServer or
CloudSolrServer (depending on whether or not you use SolrCloud). You
can also remove the solr-* and lucene-* jars from your classpath ... you
just need the solrj jar and its "standard" dependencies, which can be
found in the binary download or the compiled source code under
dist/solrj-lib.
Thanks,
