RE: How can i make a distribute search on Solr?
Thanks for your reply, I need the Federated Search. You mean this is not yet supported out of the box. So I have a question that in this situation what can Collection Distribution used for? Jarvis -Original Message- From: Ryan McKinley [mailto:[EMAIL PROTECTED] Sent: Wednesday, September 19, 2007 1:47 PM To: solr-user@lucene.apache.org Subject: Re: How can i make a distribute search on Solr? So it means that distributed search is not a basic component in Solr project. I think you just need load balancing. Solr is not a load balancer, you need to find something that works for you and configure that elsewhere. Solr works fine without persistent connections, so simple round robin DNS but it works find. Depending on your usage/loads/requirements it may or may not make sense to have your master DB in the mix. Stu is referring to Federated Search - where each index has some of the data and results are combined before they are returned. This is not yet supported out of the box ryan

multithread update client causes exceptions and dropped documents
TestJettyLargeVolume.java Description: Binary data we were doing some performance testing for the updating aspects of solr and ran into what seems to be a large problem. we're creating small documents with an id and one field of 1 term only submitting them in batches of 200 with commits every 5000 docs. when we run the client with 1 thread everything is fine. when we run it win 1 threads things go south (stack trace is below). i've attached the junit test which shows the problem. this happens on both a mac and a pc and when running solr in both jetty and tomcat. i'll create a junit issue if necessary but i thought i'd see if anyone else had run into this problem first.

Re: multithread update client causes exceptions and dropped documents
Can you start a JIRA issue and attach the patch? I have not seen this happen, but I bet it is caused by something from: https://issues.apache.org/jira/browse/SOLR-215?page=com.atlassian.jira.plugin.ext.subversion:subversion-commits-tabpanel Can we add that test to trunk? By default it does not need to be a long running test, but its nice to have in there so we can twiddle it for specific testing. thanks ryan Will Johnson wrote: one other note. the errors pop up when running against the 1.3 trunk but do not appear to happen when run against 1.2. - will On 9/19/07, Will Johnson [EMAIL PROTECTED] wrote: we were doing some performance testing for the updating aspects of solr and ran into what seems to be a large problem. we're creating small documents with an id and one field of 1 term only submitting them in batches of 200 with commits every 5000 docs. when we run the client with 1 thread everything is fine. when we run it win 1 threads things go south (stack trace is below). i've attached the junit test which shows the problem. this happens on both a mac and a pc and when running solr in both jetty and tomcat. i'll create a junit issue if necessary but i thought i'd see if anyone else had run into this problem first.

Re: Index/Update Problems with Solrj/Tomcat and Larger Files
I have had this and other files index correctly using a different combination version of Tomcat/Solr without any problem (using similar code, I re-wrote it because I thought it would be better to use Solrj). I get the same error whether I use a simple StringBuilder to created the add manually or if I use Solrj. I have manually encoded each field before passing it in to the add function as well, so I don't believe it is a content problem. I have tried to change every setting in Tomcat and Solr that I can think of, but I'm newer to both of them. So it works if you build an XML file with the same content and send it to the server using the example post.sh/post.jar tool? Have you tried messing with the connection settings? SolrServer server = new CommonsHttpSolrServer( url ); ((CommonsHttpSolrServer)server).setConnectionTimeout(5); ((CommonsHttpSolrServer)server).setDefaultMaxConnectionsPerHost(100); ((CommonsHttpSolrServer)server).setMaxTotalConnections(100); a timeout of 5ms is probably too short... ryan
Re: How can i make a distribute search on So lr?
Nutch implements federated search separately from their index generation.
My understanding is that MapReduce jobs generate the indexes (Nutch calls them
segments) from raw data that has been downloaded, and then makes them available
to be searched via remote procedure calls. Queries never pass through MapReduce
in any shape or form, only the raw data and indexes.
If you take a look at the org.apache.nutch.searcher.DistributedSearch class,
specifically the #Client.search method, you can see how they handle the actual
federation of results.
Thanks,
Stu

RE: Index/Update Problems with Solrj/Tomcat and Larger Files
Ok, I'll try to play with those. Any suggestion on the size? Something else that is very interesting is that I just tried to do an aggregate add of a bunch of docs, including the one that always returned the error. I called a function to create a SolrInputDocument and return it. I then did the following: CollectionSolrInputDocument docs = new ArrayListSolrInputDocument(); SolrServer server = new CommonsHttpSolrServer(solrPostUrl); UpdateRequest ur = new UpdateRequest(); ur.setAction( UpdateRequest.ACTION.COMMIT, false, false ); //Auto Commits on Update... ur.add(docs); UpdateResponse rsp = ur.process(server); In doing this, the program simply hangs after the last command. If I let it sit there for an amount of time, it eventually returns with the error: class org.apache.solr.client.solrj.SolrServerException (java.net.SocketException: Connection reset by peer: socket write error) However, if I go to the tomcat server and restart it after I have issued the process command, the program returns and the documents are all posted correctly!

Getting only size of getFacetCounts , to simulate count(group by( a field) ) using facets
Hi We want to (mis)use facet search to get the number of (unique) field values appearing in a document resultset. I thought facet search perfect for this, because it already gives me all the (unique) field values. But for us to be used for this special problem, we don't want all the values listed in response as there might be over 1 and we don't need the values at all, just the count of how many! I looked at http://wiki.apache.org/solr/SimpleFacetParameters and hoped to find a parameter like facet.sizeOnly = true (or facet.showSize=true , combined with facet.limit=1 or other small value) Would you accept a patch with such a feature ? It should probably be relatively easy, though not sure if fits into the concept of facets.. I looked at the code, maybe add an extra Value to returned NamedList of getFacetCounts() in SimpleFacets ?! ps: Other user having same request AFAIU : http://www.nabble.com/showing--range-facet-example-%3D-by-Range-%28-1-to-1000-%29-t3660704.html#a10229069 thanks, Laurent Hoss

We have paging of facets, so just like normal search results, it does
make sense to list the total number of facets matching.
The main problem with implementing this is trying to figure out where
to put the info in a backward compatible manner. Here is how the info
is currently returned (JSON format):
facet_fields:{
cat:[
camera,1,
card,2,
connector,2,
copier,1,
drive,2

},
Unfortunately, there's not a good place to put this extra info without
older clients choking on it. Within cat there should have been
another element called values or something... then we could easily
add extra fields like nvalues:
cat:{
nvalues:5042,

camera,1,
card,2,

Exact phrase highlighting
Hi out of there, I just walked through the mailing list archive, but I did not find an appropriate answer for phrase highlighting.

But, in this case double quoting the search expressions does not have any effect on highlighting, i.e. Assume we have the following text (of field type text) It is hard work to do the hard complex work A query for hard work (with the double quotes) results the highlighted section It is emhard/em emwork/em to do the emhard/em complex emwork/em Although I would guess that the correct answer should be It is emhard work/em to do the hard complex work Does anyone of the SOLR experts have a good answer for me?

Re: DisMax queries referencing undefined fields
: I noticed that the field list (fl) parameter ignores field names that it : cannot locate, while the query fields (qf) parameter throws an exception : when fields cannot be located. Is there any way to override this behavior and : have qf also ignore fields it cannot find? Those parameters are radically different. FL isn't evaluated untill after a query is executed and it's time to return documents ... just because the current range of documents being returned doesn't have a value doesn't mean there is a problem with the FL -- other documents in the same DocSet might have those values. It's not that Solr ignores fields in the fl that it can't locate, as it is that Solr tests each field a document to be returned has, and only returns it if the field is in the FL. In theory, field names in the FL should be tested to see if a matching field or dynamic field exists that would match and generate a warning/error if it's not -- i would consider that an FL bug. The semantics of QF follow directly from the semantics of the standard query parser: if you tell it to query against a field which does not exist for any document, then something is wrong with the request. Unlike the FL case (which is lazy for not checking that the feild exists) dismax has to check each field because it needs to know how to analyze the input for every field in the QF -- if the field doesn't exist, it can't do that. : This would be pretty helpful for us, as we're going to have a large number of : dynamic, user-specific fields defined in our schema. These fields will have : canonical name formats (e.g. userid-comment), but they may not be defined for : every document. In fact, some fields may be defined for no documents, which I : gather would be the ones that would throw exceptions. It would be nice to : provide solr a set of fields that could be searched and have it use the subset : of those fields that exist. i supose it would be possible to make an option for dismax to ignore any field it can't find, but that would be fairly kludgy and would introduce some really confusing edge cases (ie: what happens if non of the fields in QF can be found) A better option would probably be to use something like this from the sample schema.xml... !-- uncomment the following to ignore any fields that don't already match an existing field name or dynamic field, rather than reporting them as an error. alternately, change the type=ignored to some other type e.g. text if you want unknown fields indexed and/or stored by default -- !-- dynamicField name=* type=ignored / -- ...then any field name you want will work regardless of wether you are using dismax or hte standard request handler. Hmmm: it might be better though if the ignored field type was a TextField with an Analyzer that produced no tokens ... then it would drop out of the query completely ... anyone want to submit a NoOpAnalyzer :) -Hoss

rsync start and enable for multiple solr instances within one tomcat
Hi, there,
So we are using the Tomcat's JNDI method to set up multiple solr instances
within a tomcat server. Each instance has a solr home directory.
Now we want to set up collection distribution for all these solr home
indexes. My understanding is:
1. we only need to run rsync-start once use the script under any of the
solr home dirs.
2. we need to run each of the rsync-enable scripts under the solr home's
bin dirs.
3. the twiki page at
http://wiki.apache.org/solr/SolrCollectionDistributionScripts keeps
refering to solr/xxx. Is this solr the example solr home dir? If so,
would it be hard-coded in any of the scripts? For example, I saw in
snappuller line 226 (solr 1.2):
${stats} rsync://${master_host}:${rsyncd_port}/solr/${name}/
${data_dir}/${name}-wip
Is the above solr a hard-coded solr home name? If so, it's not desirable
since we have multiple solr homes with different names. If not, what is
this solr?
thanks,
-Hui

RE: How can i make a distribute search on Solr?
Nutch has two ways to make a distributed query - through HDFS(hadoop file
system) or RPC call that is in
org.apache.nutch.searcher.DistributedSearch class.
But I think these are both not good enough.
If we use HDFS to service the user's query. Stability is a problem. We must
all do the crawl , index , query on HDFS and use mapreduce. Can we trust in
hadoop all the time?:)
If we use the RPC call in nutch . Manually separate the index is required .
We will receive reduplicate result if there is reduplicate index document on
different servers. And also the data updating and single server's error is
hard to deal with.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea.
It is hard to be sure where they are going to land, and it could be
dangerous sitting under them as they fly overhead.

Filter by Group
Hey all, Let's say I have an index of one hundred documents, and these documents are grouped into 4 groups A, B, C, and D. The groups do in fact overlap. What would people recommend as the best way to apply a search query and return only the documents that are in group A? Also, how about if we run the same search query but return only those documents in groups A, C and D? I imagine that I could do this by indexing a text field populated with the group names and adding something like groups:A to the query but I'm wondering if there's a better solution.

map-reduce is more for batch jobs. Nutch only uses map-reduce for
parallel indexing, not searching.
I see... so in nutch all nodes have all the date indexed ?

Term extraction
I'm currently looking at methods of term extraction and automatic keyword generation from indexed documents. I've been experimenting with MoreLikeThis and values returned by the mlt.interestingTerms parameter and so far this approach has worked well. However, I'd like to be able to analyze documents more intelligently to recognize phrase keywords such as open source, Microsoft Office, Bill Gates rather than splitting each word into separate tokens (the field is never used in search queries so matching is not an issue). I've been looking at SynonymFilterFactory as a possible solution to this problem but haven't been able to work out the specifics of how to configure it for phrase mappings. Has anybody else dealt with this problem before or able to offer any insights into achieve the desired results? Thanks in advance, Pieter
RE: How can i make a distribute search on Solr?
I think index data which stored in HDFS and generated by map-reduce function
is used for searching in NUTCH-0.9
You can see the code in org.apache.nutch.searcher.NutchBean class . :)

separation of which docs go where happens @ a completely different layer.
We will receive reduplicate result if there is reduplicate index document on

Maybe I got this wrong...but isn't this what mapreduce is meant to deal with?
eg,
1) get the job (a query)

4) comb through the lot of results from all workers, reduce them according to

5) return the reduced results to the frontend.
And also the data updating and single server's error is

this really depends on your infrastructure + design.
Having the indexing , searching and providing of results in different layers
should make for some interesting design options...
If each searcher (or wherever the index resides) is really a small cluster of

You can also have repeated data across indexes (again, independent indexes) and
that's a more ... randomised :) way of keeping the docs safe... For example,

Re: Filter by Group
Sounds like you're on the right track, if your groups overap (i.e. a document can be in group A and B), then you should ensure your groups field is multivalued. If you are searching for foo in documents contained in group A, then it might be more efficient to use a filter query (fq) like: q=foofq=groups:A See the wiki page on common query parameters for more info: http://wiki.apache.org/solr/CommonQueryParameters#head-6522ef80f22d0e50d2f12ec487758577506d6002 cheers, Piete On 20/09/2007, mark angelillo [EMAIL PROTECTED] wrote: Hey all, Let's say I have an index of one hundred documents, and these documents are grouped into 4 groups A, B, C, and D.

RE: How can i make a distribute search on Solr?
HI,
What you say is done by hadoop that support Hardware Failure、Data
Replication and some else .
If we want to implement such a good system by ourselves without HDFS
but Solr , it's a very very complex work I think. :)
I just want to know whether there is a component existed can do the
distributed search based on Solr.

Re: Term extraction
Thanks Brian, I think the smart approaches you refer to might be outside the scope of my current project. The documents I am indexing already have manually-generated keyword data, moving forward I'd like to have these keywords automatically generated, selected from a pre-defined list of keywords (i.e. the simple approach). The data is fairly clean and domain-specific so I don't expect there will be more than several hundred of these phrase terms to deal with, which is why I was exploring the SynonymFilterFactory option.

Re: How can i make a distribute search on Solr?
Along similar lines :
assuming that i have 2 indexes in the same box , say at :
/home/abc/data/index1 and /home/abc/data/index2,
and i want the results from both the indexes when i do a search - then how
should this be 'optimally' designed - basically these are different Solr
homes and i want the results to be clearly demarcated as coming from 2
different sources.
