Re: Indexing Approach

1. We have 5 nodes and 3 zookeepers (will autoscale if needed) 2. We use java with the help of solrj / spring data for indexing. 3. We see the exception in our application so this is probably our fault and not solr's so I'm asking what is the best approach for documents with a lot of child docume

Approach for Merge Database and Files

Hi: I have two sources to indexing: Database: MetadataDB1, MetadataDB2, File Url... Files: MetadataF1, MetadataF2, File Url, Contain... I index the data base and the files. When I search, I need search and show the merge result: Database + Files (MetadataDb1, MetadataDB2, MetadataF1, MetadataF2,

Re: Approach for Merge Database and Files

Hi, I would create a search alias, that contains the latest versions of the different collections. See: https://lucene.apache.org/solr/guide/7_3/collections-api.html#collections-api Then you use this alias to search for results You get better results if you define the same schema for all colle

Re: Solr Default query parser

The "Standard Query Parser" _is_ the lucene query parser. They're the same parser. As Shawn pointed out above, they're also the default, so if you don't specify any defType, they will be used. Though if you want to be explicit and specify it anyway, the value is defType=lucene Jason On Mon, Jun

Re: Indexing part of Binary Documents and not the entire contents

Well, if you were using ERH you'd have the same problem as it uses Tika. At least if you run Tika on some client somewhere, if you do have a document that blows out memory or has some other problem, your client can crash without taking Solr with it. That's one of the reasons, in fact, that we don'

Re: Indexing Approach

Thanks for the tip. Although we have increased our application's heap to 4g and it is still not enough. I guess here are the things we think we did wrong: - Each SP call will return 15 result sets. - Each document can contain 300-1000 child documents. - If the batch size is 1000, the child docum

Well, there's a multiValued field that's just a list of whatever (string, date, numeric, etc). What's the use-case? This feels like an "XY" problem. a "dictionary" type is usually some kind of structure that how want to have operate in a specific manner. Solr doesn't really deal at that level, it
