Re: MongoDb vs Solr

MarkLogic can do many-to-many. I worked there six years ago. They use search engine index structure with generational updates, including segment level caches. With locking. Pretty good stuff. A many to many relationship is an intersection across posting lists, with transactions.

Uhm. Dude are you drinking? 1. Lucidworks would never say that. 2. Maria is not a json +MySQL. Maria is a fork of the last open source version of MySQL before oracle bought them 3.walter is 100% correct. Solr is search. The only complex data structure it has is an array. Something like mongo

The people @ Lucidworks would beg to disagree but I know exactly what you are saying Walter. A simple flat file like a cardx is fine and dandy as a Solrcloud noSQL DB. I like to express it as knowing when to fish and when to cut bait. As soon as you are in the one - many or many - many world a

timeAllowed parameter is a not a good choice for rate limiting and could crash the whole Solr cluster. In fact, timeAllowed parameter should increase the chances of crashing the whole cluster: When the timeAllowed for a query is over, it's client will get a failure but the server handling the

Hi all, why i have to choose solr if mongoDb is easier to learn and to use? Both are NoSql database, is there a good reason to chose solr and not mongoDb? thanks really much -- Ing. Viscomi Francesco

Re: Limiting the number of queries/updates to Solr

Hi Hrishikesh, I think SOLR-7344 is probably an important addition to Solr. It could help users isolate analytical queries ( streaming ) , search queries and indexing requests and throttle requests Let's continue the discussion on the Jira On Thu, Aug 3, 2017 at 2:03 AM, Rick Leir

In addition to Shawn's comments, deleted but not merged documents alter the statistics used for scoring, so the only hope that the scores are comparable would be on an optimized index. And note that I would recommend optimizing _only_ for testing, don't use it in a production system unless the

Per Text Field Similarity Measures for Learning to Rank
