Re: Long startup phase
There are no .pyc files in Solr. It's an all-Java app, no Python.
Run 'jps' to get a list of Java processes running. Then use 'jhat' or
'jstat' to examine the program.
'netstat -an | fgrep :8983' will give you a list of all sockets in use
by Solr, both client and server.

Re: Embedded Server, Caching, Stats page updates

Now for starters: if the remote server you were running solr on is more powerful then the local machine you are running your java application on, that alone could explain some performance differences (likewise for JVM settings). Most importantly: when running solr embedded in your application, there is no "stats.jsp" page for you to look at -- because solr is no longer running in a servlet container. so if you are seeing stats on your solr server that say your caches aren't being hit, the reason is because the server isn't being hit at all. : Is there some kind of property that needs to be added or adjusted for : embedded server to use cache? Should I create my own cache and wipe the rest When running an embedded solr server, the filterCache and queryResultCache will still be used. the settings in the solrconfig.xml you specify when initializing the SolrCore will be honored. you can see use JMX to monitor those cache hit rates (assuming you have JMX enabled for your application, and the appropriate setting is in your solrconfig.xml) -Hoss

TikaEntityProcessor on Solr 1.4?
Sorry to repeat this question, but I realized that it probably belonged in its own thread: The TikaEntityProcessor class that enables DataImportHandler to process business documents was added after the release of Solr 1.4, along with some other changes (like the binary DataSources) to support it. Obviously, there hasn't been an official release of Solr since then. Has anyone tried back-porting those changes to Solr 1.4? (I do see that the question was asked last month, without any response: http://www.lucidimagination.com/search/document/5d2d25bc57c370e9) The patches for these issues don't seem all that complex or pervasive, but it's hard for me (as a Solr n00b) to tell whether this is really all that's involved: https://issues.apache.org/jira/browse/SOLR-1583 https://issues.apache.org/jira/browse/SOLR-1358 Sixten

Re: disable caches in real time
: I want to know if there is any approach to disable caches in a specific core : from a multicore server. only via hte config. : I have a multicore server where the core0 will be listen to the queries and : other core (core1) that will be replicated from a master server. Once the : replication has been done, i will swap the cores. My point is that i want to : disable the caches in the core that is in charge of the replication to save : memory in the machine. that seems bizarely complicated -- replication can work against a "live" core, no need to do the swap yourself, the replicationHandler takes care of this for your transparently (ie: you have one core, replicating from a master -- the old index will be searched by users, and have caches, and when the new version of the index is ready, the replication handler will swap the *index* in that core (but the core itself never changes) ... it can even autowarm the caches on the new index for you before the swap if you configure it that way. -Hoss
Re: Autosuggest
: So there is no generally accepted preferred way to do auto-suggest? there are many generally accepted and preferred ways to do auto-suggest -- it all comes down to specifics goals and needs. for example: using the TermsComponent is really simple to setup if you want your suggestions to come from a single field of your index and be in a simple ordering -- but if you want the suggested terms to be limited based on other criteria, or if you want to influence hte ordering, by other things you need to use a complicated solution (like Facets). For people with really tricky requirements (like ordering the results by a custome rule) it can even make sense to setup a special core where each document corrisponds to a "term" to suggest, with a text field containing ngrams, and other fields containing numeric values that you use in boost functions. there are lots of options -- all of them equally accepted -- prefrence is based on needs. -Hoss
Storing RandomSortField
Hi guys, Is there any way to mak a RandomSortField be stored?

Is there any restriction on this kind of field that prevents it from being displayed in the results? Thanks, Alexandre
'Minimum Should Match' on subquery level
Hi All I need to use Lucene's `minimum number should match` option of BooleanQuery on Solr. Actually I need to do the same as DisMaxRequestHandler's `mm` parameter does but to use it on subquery level, i.e. I have complex query which consists of several Boolean subqueries and I need to specify different 'minimum number should match' threshold for each of such sub-queries. Can somebody advice me how can I do it with Solr? Thanks in advance, Myron

On 5/14/2010 12:40 PM, Shawn Heisey wrote: I downgraded to 5.0.8 for testing. Initially, I thought it was going to be faster, but it slows down as it gets further into the index. It now looks like it's probably going to take the same amount of time. On the server timeout thing - that's a setting you'd have to put in my.ini or my.cfg, there may also be a way to change it on the fly without restarting the server. I suspect that when you are running a multiple query setup like yours, it opens multiple connections, and when one of them is busy doing some work, the others are idle. That may be related to the timeout with the older connector version. On my setup, I only have one query that retrieves records, so I'm probably not going to run into that. I could be wrong about how it works - you can confirm or refute this idea by looking at SHOW PROCESSLIST on your MySQL server while it's working. I was having no trouble with the 5.0.8 connector on 1.5-dev build 922440M, but then I upgraded the test machine to the latest 4.0 from trunk, and ran into the timeout issue you described, so I am going back to the 5.1.12 connector. I just saw the message on the list about branch_3x in SVN, which looks like a better option than trunk. Shawn

If you need features not in an official release, and are looking for a codebase with updated features, I would recommend instead considering: http://svn.apache.org/repos/asf/lucene/dev/branches/branch_3x/ I am sure someone will disagree, but its my opinion that this 3.x release branch is actually more stable than you might think, it gets all the bugfixes and "safe features" from the trunk, but nothing really risky or scary. So for example, it gets a lot of bugfixes and cleanups, and gets things like improvements to spatial and new analyzers, but doesn't get the really risky stuff like flexible indexing changes from Lucene. https://svn.apache.org/repos/asf/lucene/dev/branches/branch_3x/solr/CHANGES.txt https://svn.apache.org/repos/asf/lucene/dev/branches/branch_3x/lucene/CHANGES.txt https://svn.apache.org/repos/asf/lucene/dev/branches/branch_3x/lucene/contrib/CHANGES.txt -- Robert Muir rcm...@gmail.com

how to achieve filters
Hi All I am using "dismax" query to fetch docs from solr where I have set some boost to the each fields, If I search for query "Rock" I get following docs with some boost value which I have specified, 19.494072 120 mp3 Rock 1 st name 1 19.494052 248 aac+ Rock 2 st name 2 19.494042 127 aac+ Rock 3 st name 3 19.494032 256 mp3 Rock 4 st name 5 I am looking for something below What is the best way to achieve them ? 1. Query=rock where content= mp3 where it should return only first and last docs where content=mp3 2. Query=rock where bitrate<128 where it should return only first and third docs where bitrate<128 Thanks in advance Prakash

Hi there,
trying to deploy Solr 1.4/JDK 1.6/CentOS Linux 64bit
on a new production server.
Starting Solr takes very long on this machine. In particular
it seems to hang for a minute or two showing only this on the
console:
[...@db01 backend_buildout]$ bin/solr-instance fg

Using strace shows that the process since to be waiting aka hanging
in the wait4() call below. Any idea?

Re: Multifaceting on multivalued field
Hi,
This exception is fired when you don't have this field on your index, but
this comes because you have an error in your query syntax !{ex=cars}cars,
should be {*!*ex=cars}cars , whith the exclamation inside the brackets.

Solr Cell and encrypted pdf files
Hi, I can't seem to get solr cell to index password protected pdf files. I can't figure out how to pass the password to tika and looking at ExtractingDocumentLoader, it doesn't seem to pass any pdf password related metadata to the tika parser. Whatever I do, pdfbox complains that: "The supplied password does not match either the owner or user password in the document." If i strip the password manually before trying to index the document it works What I'm I missing? thanks! yiannis
Multifaceting on multivalued field
Hi all,
I read about multifaceting [1] and tried it for myself. With
multifaceting I would like to conserve the number of documents for the
'un-facetted case'. This works nice with normal fields, but I get an
exception [2] if I apply this on a multivalued field.
Is this a bug or logical :-) ? If the latter one is the case, would
anybody help me to understand this?
Regards,
Peter.

Re: DIH. behavior after a import. Log, delete table !?
> how can i say that solr should start the jar after every > Delta-Import NOT > after every Full-Import ? You cannot distinguish between delta or full. So you need to do it in your jar program. In your java program you need to send GET method to url http://localhost:8080/solr/dataimport if result string/xml contains contains 'idle' and 'Delta Dump started' then you can truncate your table. if result string contains contains 'idle' and 'Full Dump Started' then do nothing.

how can i say that solr should start the jar after every Delta-Import NOT after every Full-Import ? -- View this message in context: http://lucene.472066.n3.nabble.com/DIH-behavior-after-a-import-Log-delete-table-tp823232p825717.html Sent from the Solr - User mailing list archive at Nabble.com.
Solr Architecture discussion
Hi, I'd like to get some architectural advices concerning the setup of a solr (v1.4) platform in a production environment. I'll first describe my targeted architecture and then ask the questions related to that environment. Here's briefly what I achieved so far: I've already setup an environment which serves as a proof of concept. This environment is composed of a master instance on one host, and a slave instance on a second host. The slave handles 2 solr cores. In the final version of the architecture I would add up one ore more SLAVE nodes depending on the request load. request | V [ MASTER [core] ] --- [SLAVE [core1] <--swap-->[core2] ] | v [index backup] The goal of this architecture is: * Isolate indexing from requesting * Enable index replication from master to slave * Control the swap between newly replicated index (use of dual core per Slave ) Here's how the whole platform works when we need to renew the index (on the slaves) 1- backup index files on master using solr backup capability (a backup is always welcome) 2- launch index creation (I'm using the delta indexing capabilities in order to limit the index generation time) 3- trigger replication from master core to slave core2 based on solr capabilities too 4- trigger swap between core 1 and core2 5- At this point Slave index has been renewed ... we can revert back to the previous index if there was any issues with the new one. As this is aimed to be a production environment, redondancy is one of the key elements, meaning that will double (or more) the front solr instances. If slave instances are not in the same network as the Master instance, our strategy will probably be to set up one of the slaves as a relay. That said, here are my questions: 1 / I'd like to have insight about issues that may happen with that kind of architecture? 2 / My first concern is about the size of the index that would need to be replicated. We need to perform indexing all day long (every 5min) and replicate as soon as the index is built. As far as I know, replication copies over all the index files. I think that there can not be delta replication (only replicating what changed). That's my assumption. But, is there any way to make a delta replication if that make any sense? 3 / How can I improve this architecture based on your own experience? Ex: Shall I use different network interface for solr commands and requests? Thank you for sharing. -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-Architecture-discussion-tp825708p825708.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: SOLR-788 and merged trunk
On 5/17/2010 3:34 PM, Shawn Heisey wrote: I am looking at SOLR-788, trying to apply it to latest trunk. It looks like that's going to require some rework, because the included constant PURPOSE_GET_MLT_RESULTS conflicts with something added later, PURPOSE_GET_TERMS. How hard would it be to rework this to apply correctly to trunk? Is it simply a matter of advancing the constant to the next bit in the mask? There's been no discussion on the issue as to whether the original patch or the alternate one is better. Does anyone know? I could not make the original patch work. I did get it to apply, but it would not compile. With some massaging, the alternate patch applied, compiled, and seems to have passed all junit tests as well. Considering that it's nearly 2 AM here, I will play further tomorrow. I did have one question that I hope someone can answer. It looks like the DIH has been moved outside the war file into separate jars that I will have to ensure are in the lib directory. Is that an accurate statement? Shawn
