Vincenzo, This is a discussion for the wikipedia 'talk' page. My sense is that information must be verifiable, and that the popularity rating at db-engines is not transparent. Would you like to start the discussion? Cheers -- Rick On August 30, 2017 5:17:25 PM MDT, Vincenzo D'Amore

Re: Indexed=false for a field,but still able to search on field.

Re: Solr client

Hi, Apart from take a look at the Solr's wiki, I think one of the main reasons why these API's are all out dated is that Solr itself provides the 'API' to many different languages in the form of output formats. Maybe you know that the main protocol used in Solr for communication with its clients

Re: Bug in Solr 6.6.0? "Cannot change DocValues type from SORTED_SET to SORTED"

This usually means you changed multiValued from true to false or vice versa then added more docs. So since each segment is its own "mini index", different segments have different expectations and when you query this error is thrown. Most of the time when you change a field's type in the schema

The thing everyone should be aware of is that those strings you see aren't just strange styles, they are actually lost code blocks - many of the code examples throughout the old Ref Guide are now missing (some, for some reason, aren't affected). IOW, if you use the old Ref Guide, you will be

Re: Index relational database

Think about making a denormalized view, with all the fields needed in one table. That view gets sent to Solr. Each row is a Solr document. It could be implemented as a view or as SQL, but that is a useful mental model for people starting from a relational background. wunder Walter Underwood

Re: SolrCloud indexing -- 2 collections, 2 indexes, sharing the same nodes possible?

Thank you, Susheel, for the quick response. So, that means that when I create a new collection, it shards will be newly created at each node, right? Thus, if I have two collections with numShards=38, maxShardsPerNode=2 and replicationFactor=2 on my 38 nodes, then this would result in each

Re: Index relational database

First, it's often best, by far, to denormalize the data in your solr index, that's what I'd explore first. If you can't do that, the join query parser might work for you. On Aug 30, 2017 4:49 AM, "Renuka Srishti" wrote: > Thanks Susheel for your response. > Here is
