Some versions of the OpenJDK doesn´t include the Rhino Engine to run javascript
dataimport. You have to use the Oracle JDK.

Re: is the SolrJ call to add collection of documents a blocking function call ?
Hi Ramdev, add() is a blocking call. Otherwise it had to start an own background thread which is not what a library like Solrj should do (how many threads at most? At which priority? Which thread group? How long keep them pooled?) And, additionally, you might want to know whether the transmission was successful, or whether your guinea pig has eaten the network cable just in the middle of the transmission. But it's easy to write your own background task that adds your documents to the Solr server. Using Java's ExecutionService class, this is done within two minutes.

Why does parameter useCompoundFile not work?

Re: PorterStemmer using example schema and data
I tried that, and it seems like recharging and rechargeable, for example, actually do stem to the same root (recharg). So why is it not working when I'm searching on my indexed sampledocs? The stemming works when I search for videos and it's actually video in the document, etc., but not for rechargeable-recharging or capability-capable, etc., even though they stem to the same root when i check them on the Admin/analysis page.

Staggering Replication start times
I am playing with an index that is sharded many times, between 64 and 128. One thing I noticed is that with replication set to happen every 5 minutes, it means that each slave hits the master at the same moment asking for updates: :00:00, :05:00, :10:00, :15:00 etc. Replication takes very little time, so it seems like I may be flooding the network with a bunch of traffic requests, and then goes away. I tweaked the replication start time code to instead just start 5 minutes after a shard starts up, which means instead of all of the slaves hitting at the same moment, they are a bit staggered. :00:00, :00:01, :00:02, :00:04 etcetera. Which presumably will use my network pipe more efficiently. Any thoughts on this? I know it means the slaves are more likely to be slightly out of sync, but over a 5 minute range will get back in sync.

Re: To truncate or not to truncate (group.truncate vs. facet)
Faceting is orthogonal to grouping, so be careful what you ask for. So adding faceting would be easy, the only reason I suggested grouping is your requirement that your brands be just a count of the number of distinct ones found, not the number of matching docs. So a really simple solution would be to forget about grouping and just facet. Then have your application change the counts for all the brand entries to 1.

If I understand it correct it will however mean that i need to return 10(brands)x100(resultToShow) = 1000 docs to facilitate that all 100 results to show is of the same brand. Correnct? And tomorrow (or later) the customer will also want a facet on 5 new fields eg. production year. How could this be handled with the above approach?

Re: querying on shards
On 3/19/2012 11:55 PM, Ankita Patil wrote: Hi, I wanted to know whether it is feasible to query on all the shards even if the query yields data only from a few shards n not all. Or is it better to mention those shards explicitly from which we get the data and only query on them. for example : I have 4 shards. Now I have a query which yields data only from 2 shards. So shoud I select those 2 shards only and query on them or it is ok to query on all the shards? Will that affect the performance in any way? I use a sharded index, but I am not a seasoned Java/Solr/Lucene developer. My clients do not use the shards parameter themselves - they talk to a a load balancer, which in turn talks to a special core that has the shards in its request handler config and has no index of its own. I call it a broker, because that is what our previous search product (EasyAsk) called it. As I understand things, the performance of your slowest shard, whether that is because of index size on that shard or the underlying hardware, will be a large factor in the performance of the entire index. A distributed query sends an identical query to all the shards it is configured for. It gathers all those results in parallel and builds a final result to send to the client. You MIGHT get better performance by not including the other shards. If the no results shard query returns super-fast, it probably won't really make any difference. If it takes a long time to get the answer that there are no results, then removing them would make things go faster. That requires intelligence on the client to know where the data is. If the client does not know where the data is, it is safer to simply include all the shards. Thanks, Shawn
RE: SOLR 3.3 DIH and Java 1.6
Taking a quick look at the code, it seems this exception could have been thrown
for four reasons:
(see org.apache.solr.handler.dataimport.ScriptTransformer#initEngine)
1. Your JRE doesn't have class javax.script.ScriptEngineManager (pre 1.6,
loaded here via reflection)
2. Your JRE doesn't have any installed scripting engines. This little program
outputs 1 engine on my JRE with 6 aliases:
[js, rhino, JavaScript, javascript, ECMAScript, ecmascript]
-
import javax.script.ScriptEngineFactory;
import javax.script.ScriptEngineManager;
public class TestScripting
{
public static void main(String args[])
{
ScriptEngineManager sem = new ScriptEngineManager();
for(ScriptEngineFactory sef : sem.getEngineFactories())
{
System.out.println(sef.getNames());
}
}
}
-
3. You specified an unsupported scripting engine name in the language
parameter (see http://wiki.apache.org/solr/DataImportHandler#ScriptTransformer)
4. The script you wrote in the script tag has errors.
Unfortunately, it looks like all 4 of these things are being checked in the
same try/catch block. So you could have any of these problems and are getting
a potentially misleading error message.
One way to eliminate all #1#2 is to run the test
org.apache.solr.handler.dataimport.TestScriptTransformer on your JRE and see
if it passes. (see here for how:

So for instance the user asks for score asc, we'd make this score asc,key asc so that results would be order by score and then by key so the results across pages would be consistent? Yep. And like I said, this is also an issue even on a single node. docid A can be before docid B, then a segment merge can cause these to be shuffled. -Yonik lucenerevolution.com - Lucene/Solr Open Source Search Conference.

Re: SolrCloud replica and leader out of Sync somehow
Thanks Yonik, I really appreciate the explanation. It sounds like the best solution for me to solve this is to add the additional sort parameter. That being said is there a significant memory increase to do this when sorting by score? I don't see how with SolrCloud I can avoid doing this, and how others wouldn't need to do the same thing.

RE: SOLR 3.3 DIH and Java 1.6
I also applied a fix to both Trunk/4.x and the 3.x branch (will be in 3.6 when
it is released). This should give you better error messages when something
goes wrong when ScriptTransformer is invoked. It will tell you that you need
1.6 only if the functionality is absent (case #1 in my last message). In case
#2 or #3 it will tell you the language you specified isn't supported. In
case #4, it will tell you the script itself is invalid.

Subject: RE: SOLR 3.3 DIH and Java 1.6
Taking a quick look at the code, it seems this exception could have been thrown
for four reasons:
(see org.apache.solr.handler.dataimport.ScriptTransformer#initEngine)
1. Your JRE doesn't have class javax.script.ScriptEngineManager (pre 1.6,
loaded here via reflection)
2. Your JRE doesn't have any installed scripting engines. This little program
outputs 1 engine on my JRE with 6 aliases:
[js, rhino, JavaScript, javascript, ECMAScript, ecmascript]
-
import javax.script.ScriptEngineFactory;
import javax.script.ScriptEngineManager;
public class TestScripting
{
public static void main(String args[])
{
ScriptEngineManager sem = new ScriptEngineManager();
for(ScriptEngineFactory sef : sem.getEngineFactories())
{
System.out.println(sef.getNames());
}
}
}
-
3. You specified an unsupported scripting engine name in the language
parameter (see http://wiki.apache.org/solr/DataImportHandler#ScriptTransformer)
4. The script you wrote in the script tag has errors.
Unfortunately, it looks like all 4 of these things are being checked in the
same try/catch block. So you could have any of these problems and are getting
a potentially misleading error message.
One way to eliminate all #1#2 is to run the test
org.apache.solr.handler.dataimport.TestScriptTransformer on your JRE and see
if it passes. (see here for how:

Thanks All
Here is the core of the SOLRJ client that ended up accomplishing what I
wanted
String fileName2 = C:\\work\\SolrClient\\data\\worldwartwo.txt;
SolrServer server = new
StreamingUpdateSolrServer(http://localhost:8080/solr/,20,8);
UpdateRequest req = new UpdateRequest(/update/extract);
ModifiableSolrParams params = null ;
params = new ModifiableSolrParams();
params.add(stream.file, new String[]{fileName2});
params.set(literal.id, fileName2);
params.set(captureAttr, false);
req.setParams(params);
server.request(req);
server.commit();
To get this to work correctly, the following server side config was needed
(I started from a barebones solr config)
1. Add apache-solr-cell-3.5.0.jar to the solrhost/lib directory (or
wherever solr can access jars) as this contains the class
ExtractingRequestHandler
2. Add the appropriate handler for /update/extract in the solrconfig.xml
(this uses the ExtractingRequestHandler class).
I'll blog about this later on for the benefit of the community at large
I'm still puzzled that there are no readily available alternatives to using
the Tika based ExtractingRequestHandler in the situation where the input
data is plain UTF-8 text files that SOLR needs to injest and index. I may
need to look into defining a custom Request Handler if that's the right way
to go.
Thanks again

Re: Any way to get reference to original request object from within Solr component?
Hi Hoss, Thanks for the pointers, and sorry, it was a bug in my code (was some dead code which was alphabetizing the facet link text and also the parameters themselves indirectly by reference). I actually ended up building a servlet and a component to print out the multi-valued parameters using HttpServletRequest.getParameterValues(myparam) and ResponseBuilder.req.getParams().getParams(myparam) respectively to isolate the problem. Both of them returned the parameters in the correct order. So I went trolling through the code with a debugger, to observe exactly at what point the order got messed up, and found the bug. FWIW, I am using Tomcat 5.5. Thanks to everybody for their help, and sorry for the noise, guess I should have done the debugger thing before I threw up my hands :-). -sujit On Mar 19, 2012, at 6:55 PM, Chris Hostetter wrote: : I have a custom component which depends on the ordering of a : multi-valued parameter.

Re: Replication with different schema
OK, I was thrown off by your use of schema, I thought you were talking about schema.xml Anyway, assuming you have some kind of loop that pages through the documents via Solr, gets the results and then sends them to another Solr server... yeah, that'll be slow. You have the deep paging problem here. I'd consider dropping into Lucene to spin through the documents, fetch them and then assemble what you need into a new SolrInputDocument that you then send to your new server. You really aren't moving any interesting data. By that I mean by the time things go through your intermediate code, they're pretty much primitive types so the fact that the various Solr indexes have different schemas really isn't relevant.

Re: To truncate or not to truncate (group.truncate vs. facet)
Ok, assuming sku is an un-tokenized field (and if it isn't, use a copyField) then just facet on that field. Then, at the app layer, combine them to get your aggregate counts. So your raw return would have Audi A4 (2) Audi A5 (1) Audi S8 (2) Volvo V50 (1) The app would have to be smart enough to spin through the sku facet and just know that the three Audi SKUs need to be rolled up into one Audi entry. This could be simple if the rule were that the SKU always started with the brand name And similarly for the other SKUs. Crude, but it'd work.

I tweaked the replication start time code to instead just start 5 minutes after a shard starts up, which means instead of all of the slaves hitting at the same moment, they are a bit staggered. :00:00, :00:01, :00:02, :00:04 etcetera.
