Re: logging support in Lucene code

Lucene does not use a logger framework. But if you are using Solr then you can route the infoStream logging to Solr's log files by setting an option in the solrconfig.xml. See http://lucene.apache.org/solr/guide/6_6/indexconfig-in-solrconfig.html#IndexConfiginSolrConfig-OtherIndexingSettings On Fr

Disadvantages of having many cores

Hi, I am working on a log management tool and considering to use solr to index/search the logs. I have few doubts about how to organize or create the cores. The tool should process 200 million events per day with each event containing 40 to 50 fields. Currently I have planned to create a

Re: Disadvantages of having many cores

You're better off just using one core. Perhaps think about pre-processing the logs to "summarize" them into less "documents" I do this and in my situation i summarize things like, user-hits-item, for example. so i find all the times a certain user had hits on a certain item in one day and put tha

Issues querying date fields (date fields stored as text)

Hi all, I’m using Lucence Solr (Lucidworks ) as the search index and its a schemaless search engine to index outlook files. I have been using it since version 2.0.* and have an issue with querying dates. The older versions were mapping( date_created, mail from_date etc) to date datatype making

This question has been asked before. I found a few postings to Solr user and a couple on Google-in-the-large. But I am still not sure which is best. My project currently has two distinct datasets (documents) with no shared fields. But at times, we need to query across both of them. So we

RE: CDCR - how to deal with the transaction log files

Amrit, Problem solved! My biggest mistake was in my SOURCE-side configuration. The zkHost field needed the entire zkHost string, including the CHROOT indicator. I suppose that should have been obvious to me, but the examples only showed the IP Address of the target ZK, and I made a poor assumpt

RE: CDCR - how to deal with the transaction log files

You don't need to start cdcr on target cluster. Other steps are exactly what I did. After disable buffer on both target and source, the tlog files are purged according to the specs. -- Thank you Sean From: Patrick Hoeffel mailto:patrick.hoef...@polarisalpha.com>> Date: Friday, Jul 28, 2017, 4
