Re: broken links returned from solr search
OK thanks. So I guess I will set up my own "normal" webserver and have the solr server a sort of private web-based API (or possibly a front-end that, when a user clicks on a search result link, just redirects the user to my "normal" web server that has the related file). That's easy enough. If that's not how solr is supposed to be used, please feel free to let me know. Thanks!

Re: documentCache not used in 4.3.1?
That's a good idea, I'll try that next week. Thanks!

But do note that the underlying cache only gets filled when getting documents to return in query results, since there's no autowarming going on it may come and go. But you can test this pretty quickly by lengthening your autocommit interval or just not indexing anything for a while, then run a bunch of queries and look at your cache stats. That'll at least tell you whether it works at all. You'll have to have hard commits turned off (or openSearcher set to 'false') for that check too.

Re: Varnish
Solr HTTP caching also support "e-tags". These are unique keys for the
output of a query. If you send a query twice, and the index has not
changed, the return will be the same. The e-tag is generated from the
query string and the index generation number.
If Varnish supports e-tags, you can keep some queries cached longer than
your timeout.

Re: Improving performance to return 2000+ documents
Hello Utkarsh, This may or may not be relevant for your use-case, but the way we deal with this scenario is to retrieve the top N documents 5,10,20or100 at a time (user selectable). We can then page the results, changing the start parameter to return the next set. This allows us to 'retrieve' millions of documents - we just do it at the user's leisure, rather than make them wait for the whole lot in one go. This works well because users very rarely want to see ALL 2000 (or whatever number) documents at one time - it's simply too much to take in at one time. If your use-case involves an automated or offline procedure (e.g. running a report or some data-mining op), then presumably it doesn't matter so much it takes a bit longer (as long as it returns in some reasonble time). Have you looked at doing paging on the client-side - this will hugely speed-up your search time.

Re: documentCache not used in 4.3.1?
Tim: Yeah, this doesn't make much sense to me either since, as you say, you should be seeing some metrics upon occasion. But do note that the underlying cache only gets filled when getting documents to return in query results, since there's no autowarming going on it may come and go. But you can test this pretty quickly by lengthening your autocommit interval or just not indexing anything for a while, then run a bunch of queries and look at your cache stats. That'll at least tell you whether it works at all. You'll have to have hard commits turned off (or openSearcher set to 'false') for that check too.

Re: broken links returned from solr search
There's nothing built into the indexing process that stores URLs allowing you to fetch the document, you have to do that yourself. I'm not sure how the link is getting into the search results, you're assigning "doc1" as the ID of the doc, and I think the browse request handler, aka Solaritas is constructing the link as best it can. But that is only demo code, not intended to fetch the document. In a typical app, you'll construct a URL for display that has meaning in _your_ environment, typically some way for the app server to know where the document is and how to fetch it. the browse request handler is showing you how you'd do this, but isn't meant to actually fetch the doc.

RE: documentCache not used in 4.3.1?
Yes, we are softCommit'ing every 1000ms, but that should be enough time to see metrics though, right? For example, I still get non-cumulative metrics from the other caches (which are also throw away). I've also curl/sampled enough that I probably should have seen a value by now. If anyone else can reproduce this on 4.3.1 I will feel less crazy :).

Re: Solr 4.3.0 DIH problem with MySQL datetime being imported with time as 00:00:00
So disabling convertType does provide a workaround for my problem with datetime column. But the problem still exists when convertType is enabled because DIH is not doing the conversion correctly for a solr date field. Solr date field does have a time portion but java.sql.Date does not. So DIH should not be calling ResultSet.getDate() for a solr date field. It should really be calling ResultSet.getTimestamp() instead. Is the fix this simple? Am I missing anything? If the fix is this simple I can submit and commit a patch to DIH. Bill On Sat, Jun 29, 2013 at 12:13 PM, Bill Au wrote: > Setting convertType=false does solve the datetime issue.

Sorry, i thought it was obvious. The links that are broken are the links that are returned in the search results. Using the example in the documentation I mentioned below, to load a word doc via curl "http://localhost:8983/solr/update/extract?literal.id=doc1&commit=true"; -F "myfile=@myworddoc.doc" the broken link that shows up in the search results is http://localhost:8983/solr/collection1/doc1 so I just need to know where in the solr config to be able to handle requests when the URL points to collection/some_doc On Jun 29, 2013, at 1:08 PM, Erick Erickson wrote: > What links?

Re: FileDataSource vs JdbcDataSouce (speed) Solr 3.5
Mike: One issue is that you're forcing all the work onto the Solr server, and single-threading to boot by using DIH. You can consider moving to a SolrJ model where you can have N clients sending data to Solr if you can partition the data up amongst the N clients cleanly.

Re: Improving performance to return 2000+ documents
Well, depending on how many docs get served from the cache the time will vary. But this is just ugly, if you can avoid this use-case it would be a Good Thing. Problem here is that each and every shard must assemble the list of 2,000 documents (just ID and sort criteria, usually score). Then the node serving the original request merges the sub-lists to pick the top 2,000. Then the node sends another request to each shard to get the full document. Then the node merges this into the full list to return to the user. Solr really isn't built for this use-case, is it actually a compelling situation? And having your document cache set at 1M is kinda high if you have very big documents.

Re: Solr 4.3.0 DIH problem with MySQL datetime being imported with time as 00:00:00
Setting convertType=false does solve the datetime issue. But there are now other columns that were working before but not working now. Since I have already done some research into the datetime to date issue and not been able to find a solution, I think I will have to keep convertType set to false and deal with the other column type that are not working now.

Re: cores sharing an instance
Cores can be reloaded, they are inside solrcore loader /I forgot the exact name/, and they will have different classloaders /that's servlet thing/, so if you want singletons you must load them outside of the core, using a parent classloader - in case of jetty, this means writing your own jetty initialization or config to force shared class loaders. or find a place inside the solr, before the core is created. Google for montysolr to see the example of the first approach. But, unless you really have no other choice, using singletons is IMHO a bad idea in this case Roman On 29 Jun 2013 10:18, "Peyman Faratin" wrote: > > its the singleton pattern, where in my case i want an object (which is RAM expensive) to be a centralized coordinator of application logic. > > thank you > > On Jun 29, 2013, at 1:16 AM, Shalin Shekhar Mangar wrote: > > > There is very little shared between multiple cores (instanceDir paths, > > logging config maybe?).

Re: Schema design for parent child field
Both dynamic fields and multivalued fields are powerful Solr features that can be used to great effect, but only is used in moderation - a relatively small number of discrete values (e.g., a few dozens of strings.) Anything more complex and you are asking for trouble and creating a pseudo-schema that will be difficult to maintain or for anybody else to comprehend. So, the simple answer to your question: Flatten, in the most straightforward manner - each instance of a "record type" should be a discrete Solr document, give each "record" its own "id" to be the Solr document key/ID. Solr can support multiple document types in the same collection, or you can store each record type in separate collection. The simplest, cleanest structure is to store each record type in a separate collection and then use multiple Solr queries to emulate SQL join operations as needed. But if you would prefer to "mash" multiple record types into the same Solr collection/schema, you can do that too. Make the schema be the union of the schemas for each record type - Solr/Lucene has no significant overhead for fields which do not have values present for a given document. Each document would have a unique ID field. In addition, each document would have a parent field for each record type, so you can quickly search for all children of a given parent. You can have one common parent ID if you assign unique IDs to all children across all record types, but it can sometimes be cleaner for the child ID to reset to zero/one for each new parent. It's merely a question of whether you want to have a single key value or a tuple of key values to identify a specific child. You can duplicate a subset of the parent fields in each child to simulate the effect of a simple join in a single clean query. But you can do a separate query to get parent record details. -- Jack Krupansky -Original Message- From: Sperrink Sent: Saturday, June 29, 2013 5:08 AM To: solr-user@lucene.apache.org Subject: Schema design for parent child field Good day, I'm seeking some guidance on how best to represent the following data within a solr schema.
