Use copyField with wildcard in source; how then to work out where a value came from?

I've got a collection for which the schema has a number of copyFields that have a wildcard in the source: The idea is that I have fields in each document that contain language-specific values in fields that have field names that end in a language tag, i.e., "skos_prefLabel-en", "skos_prefLabel

Re: avgFieldLength calculation in BM25 in solr 7.4

Hi, Looking at the source code and term frequencies, it looks like: fieldLength = number of tokens prior to ngram filter processing avgFieldLength = / As you are using n-gram then 11 is the total number of terms while fieldLegth is 2. See: https://lucene.apache.org/core/7_4_0/core/org/apache

Re: Autoscaling in 8.2

You can have replication policies if you don’t want to replicate manually, but automatically: https://lucene.apache.org/solr/guide/7_1/solrcloud-autoscaling-auto-add-replicas.html >> Am 31.10.2019 um 15:55 schrieb Pranaya Behera : > So my setup is this: > 1 node > 1 collection (created via col

Re: Autoscaling in 8.2

So you want the new node to host some part of the original collection, right? use the Collections API ADDREPLICA or MOVEREPLICA commands is the easiest. Best, Erick > On Oct 31, 2019, at 10:55 AM, Pranaya Behera wrote: > > So my setup is this: > 1 node > 1 collection (created via collection AP

Re: Autoscaling in 8.2

So my setup is this: 1 node 1 collection (created via collection API) 1 shard 1 replica This node is connected to zookeeper. Now let's say I added one more node to the zookeeper, this node is new, hence there won't be any collection created for me automatically. It is a barebane node i.e. connecte

Re: DIH across two SQL DBs

Hmm, I'll have a look, but the SELECT is a bit more involved so the IDs from the other DB will be OR'ed into the WHERE clause, i.e. be added to those selected from other part of the where clause, so it's not a pure join. I'll think some more -- Jan Høydahl, search solution architect Cominvent A

You need to create a replica of the collection on the other node: https://lucene.apache.org/solr/guide/6_6/collections-api.html See addreplica >> Am 31.10.2019 um 09:46 schrieb Pranaya Behera : > Hi, > I have one node started with solrcloud. I have created one collection > with the defaul

Re: Autoscaling in 8.2

I really don’t understand the question. If you’ve created a new collection, presumably it’s got a different name, correct? So you need to send some documents to that collection and then query it for it to “do any work”. I.e. http://localhost:8983/solr/original_collection/update…. http://localho

DIH across two SQL DBs

I need a SELECT which filters IDS based on an ‘id’ list coming from another database, i.e. SELECT * FROM maindb.maintable WHERE id IN (SELECT myid FROM otherdb.other_table). The docs are fetched from a MySql DB while the list of IDs to includ in that first SELECT WHERE statement is fetched fro
