Solr Merge Index

Hello I have two sources - Sitecore web index (core 1) and a database table (core 2). I have created core 3 which is a merge of core1 and core 2. http://localhost:8983/solr/admin/cores?action=mergeindexes=core3=sitecore_web_index=core2 But when someone publishes a page on Sitecore, the

Re: Shard vs Replica

To understand shard & replica, let's first understand what is sharding and why it is needed. Sharding - Assume your index grows large that it doesn't fit into a single machine (for e.g. your index size is 80GB and your machine is 64GB in which case index won't fit into memory). Now to get

Re: Shard vs Replica

A collection in SolrCloud is a logical entity that encapsulates documents that confirm to a shared schema. As a distributed system, the data needs to be split and so the collection is logically split into 'Shards'. Shard(s): * don't represent a physical index. * are logical entities Replica: *

Shard vs Replica

Hey, I have have the same question on freenode channel , people answered me , but I believe that I still got doubts. Just because I never had approach to such data store technologies before it makes me hardly understand what is exactly is replica and shard in solr. I believe once I

Re: SolrCloud Node fails that was hosting replicas of a collection

I'd try to figure out what was up with my installation that using the collections API fails rather than continue down the track of using the core admin API. bq: However, since the newly added Sold node is down, it throws Exception " One of the nodes is down" and hence the operation fails. This

Re: CloudSolrServer with multiple zookeeper cluster setup.

CloudSolrServer (and I'm assuming you're in the 4x code line, that's now CloudSolrClient) takes an ensemble, here are two examples: "host1:2181,host2:2181,host3:2181/mysolrchroot" "zoo1.example.com:2181,zoo2.example.com:2181,zoo3.example.com:2181" Best, Erick On Wed, Jul 6, 2016 at 11:48 AM,

Could you index it, do the 'like this' and then delete it from the index? All in one smooth user experience obviously. (Just throwing it out there). Sas -Original Message- From: Charlie Hull [mailto:char...@flax.co.uk] Sent: Wednesday, July 6, 2016 11:02 AM To:

Re: Full re-index without downtime

A variation on #1 here - Use the same cluster, create a new collection, but use the createNodeSet option to logically partition your cluster so no node has both the old and new collection. If your clients all reference a collection alias, instead of a collection name, then all you need to do

CloudSolrServer with multiple zookeeper cluster setup.

Hi, In our production we have a solr cloud setup with zookeeper cluster setup. I want to shift to CloudSolrServer from httpsolrserver is there any way to specify all the ip addresses of zookeeper machines while instantiating CloudSolrServer, so that i will have an automatic fallback mechanism. PS

Re: SolrCloud Node fails that was hosting replicas of a collection

Hi Erick, Thanks for your reply, but I did used the ADD REPLICA api at the first. However, since the newly added Sold node is down, it throws Exception " One of the nodes is down" and hence the operation fails. I noticed that the node becomes GREEN only after adding the core via Admin UI.

Re: Post filter with boolean query

Not from the response, but a simple approach in a controlled environment, i.e. one where only _you_ are querying the index and there is no indexing going on is to look at the admin UI>>your_core>>plugins/stats>>caches>>filterCache. You'll see the insertions/deletions/hits count. So, after a

Re: Full re-index without downtime

There are two options as I see it.. 1. Do something like you describe and create a secondary index, index into it, then switch... I personally would create a completely separate solr cloud alongside my existing one vs new core in the same cloud as you might see some negative impacts on GC caused

Full re-index without downtime

Hi everyone, In my environment, I have use cases where I need to fully re-index my data. This happens because Solr's schema requires changes based on changes made to my data source, the DB. For example, my DB schema may change so that it now has a whole new set of field added or removed (on

Re: Solr more like this

So, if you already indexed N pdfs you can use the MLT request handler to look for similar documents to a specific text. This means you need to manually extract the content from the pdf ( like using Tika for example) and then passing that to the specific request handler.

Post filter with boolean query

Hi, I am trying to apply a filter by specifying cost=100, but I would like to use boolean query on lines described below and it seems to be filtering documents; not sure if it's doing pre-filtering or post-filtering. But, I saw some old post that "if the query inside the filter does not have a

Re: Getting a hit on "the}" but not on "the" or "}"

Yes and No. WDFF does, indeed, break things up. But they're also sequential and you can often get what you want via phrase searches. But what you have now puts junk in your index. What use is "the}" as a single token? It's up to you, but consider cleaning that sort of stuff up with, say a regex

Again I have to insert the larger company view: * if your company is largish, you may have a load balancer hardware already in use by systems. * If you are using a Cloud system for the Solr, then you can probably use a load balancer provided by the cloud provider, and this may be cheaper

Thanks Erick. Moving stopword factory to after WDFF fixed the problem; I no longer get a hit on "the}" or the variations of "the]", "the.", etc., I did not have to change preserverOriginal from 1 to 0. Regarding preserverOriginal in WDFF, I have it set to 1 because my understanding of it means
