Re: Function Query with multi-value field

Re: Getting list of unique values in a field

The Solr ref-guide has examples which show how to do this too. Take a look at some of the faceting examples here: https://lucene.apache.org/solr/guide/8_1/json-facet-api.html#bucketing-facet-example Best, Jason On Fri, Jul 12, 2019 at 9:50 AM David Hastings wrote: > > i found this: > > https:/

One of our clusters got as large as 40 c4.8xlarge, another is happy with 4 m4.xlarge and could probably handle the load with one of them. It depends on the number of documents, query load, types of queries, frequency of updates, all sorts of things. wunder Walter Underwood wun...@wunderwood.org

Removing message_raw_header prefix from field names

Hi, When I index EML files to Solr, I realised that there are certain fields which are prefix with message_raw_header (Eg: message_raw_header_x_receiver). There is no message_raw_header prefix in the EML files. Is there any way that we can remove the message_raw_header for all the fields directly

Upload/use a plugin JAR in ZooKeeper

Hi, I'm trying to use a plugin JAR containing a custom query parser. I've been able to get this to work the "simple" way, by putting the JAR in the file system, and specifying basic values in solrconfig.xml. No problem doing it this way. But I'm running in SolrCloud mode and I'd like to t
