Hey,
Is it possible to change the url for solr admin??
What i want is :
http://192.168.0.89:8983/solr/private/coreName/admin
i want to add /private/ before the coreName. Is that possible? If yes how?
Ankita.
I have figured out what was wrong... The field Warehouse was not marked as
indexed... It was being stored, but not indexed... It is now working as
expected.
Thanks.

Hi,
Is SQL Like operator feature available in Apache Solr Just like we have it
in SQL.
SQL example below -
*Select * from Employee where employee_name like '%Solr%'*
If not is it a Bug with Solr. If this feature available, please tell the
examples available.
Thanks!

Actually it is available, you need to use the ReversedWildcardFilterFactory
which I am sure you can Google for.
Solr and SQL address different problem sets with some overlaps but there are
significant differences between the two technologies. Actually '%Solr%' is a
worse case for SQL
Hi,
this is not exactly true. In Solr, you can't have the wildcard operator
on both sides of the operator.
However, you can tokenize your fields and simply query for Solr. This
is what's Solr made for. :)

Good point about just tokenizing the fields :)

wildcard operator at either or both ends of a term. Adding

Hi all,
Is there a good guide on using Solr components as a dictionary
matcher? I'm need to do some pre-processing that involves lots of
dictionary lookups and it doesn't seem right to query solr for each

Thanks in advance,

Yes, that's expected behavior. When you optimize, all segments are
copied over to new
segments(s). Since all changed/new segments are replicated to the slave,
you'll (temporarily) have twice the data on your disk.
You can stop optimizing, it's often not really very useful despite its name.

Optimization merges index to a single segment (one huge file), so entire index
will be copied on replication. So you really do need 2x disk in some cases
then.
Do you really need to optimize? We have a pretty big total index (about 200
million docs) and we never optimize. But we do have a

Greetings guys,
I have been thinking of using Solr as a simple database due to it's
blinding speed -- actually I've used that approach in some projects with
decent success.
Any thoughts on that?
Thanks,
MM.
I guess it could be many things.
Typically an easy one to spot is if you have insufficient heap (i.e.
your 16Gb) and the jvm is full gc'ing constantly and not freeing up any
memory and using lots of cpu. This would make solr slow and hangs up
as well during potentially long gc pauses.
add:
Other than it isn't a database?
If you want a key/value store, use one of those. If you want a full DB with
transactions, use one of those.

It is not a horrible idea. Lucene has a pretty reliable index now (it should
not get corrupted). And you can do backups with replication.
If you need ranked results (sort by relevance), and lots of free-text queries
then using it makes sense. If you just need boolean search and maybe some
One other potentially huge consideration is how updatable you need documents
to be. Lucene only can replace existing documents, it cannot modify existing
documents directly (so an update is essentially a delete followed by an insert
of a new document with the same primary key). There are
Thanks Robert.
We optimize less frequently than we used to. Down to twice a month from once
a day.
Without optimizing the search speed stays the same, however the index size
increases to 70+ GB.
Perhaps there is a different way to restrict disk usage.

Hi,
I was wondering if it's a good idea to expose Solr to the outside world,
so that our clients running on smart phones will be able to use Solr.
If we decide to do this, what's the security concerns about it?
For example, someone suggested we should limit the number of
rows requested in order
Start here:
http://lucene.apache.org/solr/api/org/apache/solr/analysis/NGramFilterFactory.html
But the idea is that you define a field with the NGramFilterFactory and it

Do you do a lot of deletes (or 'updates' of existing documents)?
Do you store lots of large fields? Maybe you can use compressed fields in that
case (we never have tried it so I cannot confirm how well it works or performs).
You can also turn off things like norms and vectors, etc. if you
Well,
I've done a lot of work with MySQL and content management systems -- and
frankly whenever I have to integrate with Solr or do some Lucene work I am
amazed at the speed -- even when I index web pages for search -- MySQL
pales by comparison when data sets get large (2 million rows)
Thanks,
You would need to setup request handlers in solrconfig.xml to limit what types
of queries people can send to SOLR (and define things like max page size, etc).
You need to restrict people from sending update/delete commands as well.
Then at the minimum, setup some proxy in front of SOLR that

Be aware that even /select could have some harmful effects, see

Even disregarding that issue, /select is a potential gateway to any request

I think you can address a lot of these concerns by running some proxy in front
of SOLR, such as HAProxy. You should be able to limit only certain URIs (so
you can prevent /select queries).HAProxy is a free software load-balancer,
and it is very configurable and fairly easy to setup.

Yeah, actually our firewalls/loadbalancers can handle these issues.
If they don't, then I'll use HAProxy.
