Re: Parent Child Schema Design

[Pranaya Behera]

Hi Binay,
  Are you saying there is no need to add anything to the 
existing schema that I have ? While indexing all I have to provide is a 
_childDocuments_ key and the key => value pair as per I want without 
needing to specify it in the schema.xml ?

You just need to add a json key _childDocuments_ to the doc and specify the
child doc as the value for this key.
There was a similar question on the mailing list earlier. You can find that

Yes. Provided your fields are already defined.

This could be a permissions problem -- for example, perhaps you started 
it as root the first time and are now attempting to start it as some 
other user.

Re: Parent Child Schema Design

[Binoy Dalal]

To clarify, what I meant was any field that you wish to use either  in your
child or parent document has to already be defined in the schema.
You need to define these fields normally, meaning no you are not required
to make any special changes to the field definition for use in either
parent or child docs.
Once done, you can use these fields in the parent as well as child docs.

I suggest you first try out the example given in yoniks blog. It's fairly
simple and will give you a good idea of the concepts and the steps
involved. Once you're confident in your understanding of the concepts,
you'll be able to implement your own setup easily.

No real limit (other than the normal ones... you can't have more than
2B docs in a single segment)... probably just a practical limit based
on memory (they are all indexed atomically at the same time)

Solrcloud for Java 1.6

[Aswath Srinivasan (TMS)]

Hi fellow developers,

I have a situation where the search front-end application is using java 1.6. 
Upgrading Java version is out of the question.

Planning to use Solrcloud 5.x version for the search implementation. The show 
stopper here is, solrj for solrcloud needs atleast java1.7

What best can be done to use the latest version of solrcloud and solrj for a 
portal that runs on java 1.6?

I was thinking, in solrj, instead of using zookeeper (which also acts as the 
load balancer) I can mention the exact replica's http://solr-cloud-HOST:PORT 
pairs using some kind of round-robin with some external load balancer.

Any suggestion is highly appreciated.

Facetting on EnumFields using JSON API (Bug?)

[Niko Weh]

Hi everyone,


I've posted in #solr and #solr-dev about this and was redirected here.

I'm having trouble with the JSON Facet API. Unsure whether it is a bug
or a usage error, but I couldn't find anything on google or the
documentation about this.

When facetting on an EnumField, i'm getting an error when using the JSON
API (but not the legacy API). For example, with a datetime field
"insertdate" and an EnumField state,

  ..&facet=on&rows=0&facet.field=state&facet.field=insertdate'

works fine.

Using the JSON API:

  json.facet={
states: {field: state}, dates: {field: insertdate}
  }

throws an error:

  "error":{
"msg":"Expected numeric field type
:state{type=auState,properties=indexed,stored,docValues}",
"code":400}

It works fine though when i drop the "states: {...}" facet.

Example Setup and full error messages:
https://gist.github.com/xou/33fd7aab7afe3cebb28b

This is with current trunk solr, but i've seen the same behaviour in
5.4.0 and,  IIRC, 5.3.

I did hack together a quick patch[1], in case this is a bug, which makes
the query work and yields the same results for my test setup with ~20k
entries as the legacy facet api (although i'm pretty new to solr, so
that patch might not achieve this in the right way). And maybe it's
usage error (in which case though, the error message could probably need
a bit improving ;))

Cheers!

Niko

The last version of Solr (and SolrJ) that supports Java 6 is 4.7.2.  I
would strongly NOT recommend using the CloudSolrServer object from SolrJ
4.7.2 with SolrCloud 5.x.  SolrCloud is evolving *very* quickly from
version to version, so different versions may not work together well. 
With the difference being a *major* version, I would not be surprised if
doesn't work at all.

You have two choices here, assuming you'll be using SolrJ 4.7.2.

One choice is to put a load balancer in front of your SolrCloud and use
that host in the HttpSolrServer object.  I use haproxy for a Solr load
balancer, it works very well.

The other choice is to put all of the server URLs into an instance of
LBHttpSolrServer.  I have never used this object, but this is the same
object that CloudSolrServer uses internally, so it should work.  It will
not respond as quickly to clusterstate changes as CloudSolrServer would,
because it cannot talk to Zookeeper.

Cross-version compatibility with HttpSolrServer and LBHttpSolrServer
should be very good.  It's just CloudSolrServer that doesn't work well
when you mix versions.

Thanks,
Shawn

Solr UIMA Custom Annotator PEAR file installation on Linux

1) Is the solrconfig.xml file actually present under /configs/contracts?
Also is it the correct one that you've uploaded?
2) Have you linked the configset to the collection?

Re: I cannot create replica in Solr

[Erick Erickson]

Those files have nothing to do with an uploaded config!

You _should_ be seeing files like "solrconfig.xml", "schema.xml" (or
"managed_schema"), perhaps files like "stopwords.txt" and the like.
Essentially, everything that you would expect to find in the "conf"
directory for Solr. Somewhere, you must have a set of Solr config
files that are supposed to be part of your standard deployment,
"those" are the files that should be in Zookeeper in the configs node.

I have no clue how you got those files into Zookeeper, but they're
completely unknown to Solr, Solr is looking for "solrconfig.xml" and
the like.

Best,
Erick

Re: Manage schema.xml via Solrj?

[Erick Erickson]

I'd ask first what the high-level problem you're trying to solve is, this
could be an XY problem.

That said, there's the Schema API you can use, see:
https://cwiki.apache.org/confluence/display/solr/Schema+API

You can access it from the SolrJ library, see
SchemaRequest.java. For examples of using this, see:
SchemaTest.java

to _get_ the Solr source code to see these, see:
https://wiki.apache.org/solr/HowToContribute

Solr search and index rate optimization

[Zap Org]

i wanted to ask that i need to index after evey 15 min with hard commit
(real time records) and currently have 5 zookeeper instances and 2 solr
instances in one machine serving 200 users with 32GB RAM. whereas i wanted
to serve more than 10,000 users so what should be my machine specs and what
should be my architecture for this much serve rate along with index rate.
my index size is 30GB increases gradually. Thankyou in advance and i am
newbee hoping to get response

Re: Solrcloud for Java 1.6

[Zap Org]

i have solr5.0.0 installed in one machine with JVM specs java 1.7 32GB RAM
now from another machine i am sending query request to this machine with
specs JAVA 1.6
so what really happening solr5.0.0 (1.7) is communicating with
solrj5.0.0(1.6)


provide your architecture detail ill further explain it

Re: Solrcloud for Java 1.6

[Walter Underwood]

You can have multiple Java versions installed on the same system. Well, the 
same non-Windows system. Use the PATH environment variable to set the right 
Java for each application.

If you really, really must run Java 1.6 for everything, you will not be running 
Solr 5.x. I think the switch to require Java 7 was made at some point in the 
4.x development.

The system with SolrJ 5.0.0 must have a newer Java version installed.
It is simply not possible to run Solr or SolrJ 5.0.0 with Java 6.

If you attempt to run version 4.8 or later with Java 6, you'll get an
error that looks like this:

Exception in thread "main" java.lang.UnsupportedClassVersionError:
org/apache/solr/xxx/yyy: Unsupported major.minor version 51.0

Here is some information about what the specific major.minor version
number means:

http://stackoverflow.com/a/11432195

Just for giggles, I attempted to compile SolrJ (which is a standalone
module not dependent on the rest of Solr) in the branch_5x checkout with
the build script changed to produce jars compatible with version 1.6.
It would not compile when the target was set to 1.6, because the way the
code is written *requires* Java 7, and has since version 4.8.

Thanks,
Shawn
