RE: newbie question
Hi Darshan, It looks like you are listing the instanceDir's name twice in the create collection command, it should be $ solrctl --zk host:2181/solr --solr host:8983/solr/ collection --create Catalog_search_index -s 10 -c Catalog_search_index Without the extra ". Catalog_search_index" at the end. Also, because your new collection's name is the same as the instanceDir's, you could just omit that parameter and it should work ok. Try that and see if it works. Good luck, Gonzalo -Original Message- From: Darshan Pandya [mailto:darshanpan...@gmail.com] Sent: Wednesday, September 7, 2016 12:02 PM To: solr-user@lucene.apache.org Subject: newbie question hello, I am using solr cloud with cloudera.

RE: variaton on boosting recent documents gives exception
Hello Michael, You can always change the type of your sortyear field to an int, or create an int version of it and use copyField to populate it. And using NOW/YEAR will round the current date to the start of the year, you can read more about this in the Javadoc: http://lucene.apache.org/solr/4_10_3/solr-core/org/apache/solr/util/DateMathParser.html You can test it using the example collection: http://localhost:8983/solr/collection1/select?q=*:*boost=recip(ms(NOW/YEAR,manufacturedate_dt),3.16e-11,1,1)fl=id,manufacturedate_dt,score,[explain]defType=edismax and checking the explain field for the numeric value given to NOW/YEAR vs NOW/HOUR, etc. Gonzalo -Original Message- From: Michael Lackhoff [mailto:mich...@lackhoff.de] Sent: Thursday, February 12, 2015 8:57 AM To: solr-user@lucene.apache.org Subject: variaton on boosting recent documents gives exception Since my field to measure recency is not a date field but a string field (with only year-numbers in it), I tried a variation on the suggested boost function for recent documents: recip(sub(2015,min(sortyear,2015)),1,10,10) But this gives an exception when used in a boost or bf parameter. I guess the reason is that all the mathematics doesn't work with a string field even if it only contains numbers. Am I right with this guess? And if so, is there a function I can use to change the type to something numeric? Or are there other problems with my function? Another related question: as you can see the current year (2015) is hard coded. Is there an easy way to get the current year within the function? Messing around with NOW looks very complicated. -Michael
RE: Find duplicates
Have you tried using result grouping for your query? There are some very good examples in the wiki: https://wiki.apache.org/solr/FieldCollapsing Gonzalo -Original Message- From: Peter Kirk [mailto:p...@alpha-solutions.dk] Sent: Tuesday, December 02, 2014 9:58 AM To: solr-user@lucene.apache.org Subject: Find duplicates Hi Is it possible to formulate a Solr query which finds all documents which have the same value in a particular field? Note, I don't know what the value is, I just want to find all documents with duplicate values. For example, I have 5 documents: Doc1: field Name = Peter Doc2: field Name = Jack Doc3: field Name = Peter Doc4: field Name = Paul Doc5: field Name = Jack If I executed the query, it would find documents Doc1 and Doc3 (Peter is the same), and Doc2 and Doc5 (Jack is the same). Thanks, Peter
RE: Help on Notification for SOLR
Hi, You might want to take a look at the UpdateRequestProcessor and UpdateRequestProcessorChain classes: https://wiki.apache.org/solr/UpdateRequestProcessor and http://lucene.apache.org/solr/4_10_2/solr-core/org/apache/solr/update/processor/UpdateRequestProcessorChain.html You can hook a chain to your update request handler and use a ScriptUpdateProcessor to implement your notification system. https://wiki.apache.org/solr/ScriptUpdateProcessor Hope this helps, Gonzalo -Original Message- From: EXTERNAL Taminidi Ravi (ETI, Automotive-Service-Solutions) [mailto:external.ravi.tamin...@us.bosch.com] Sent: Monday, November 24, 2014 2:35 PM To: solr-user@lucene.apache.org Subject: Help on Notification for SOLR Hello, I am working on implementing a notification system when there is any change in the solr index (Addition or removal of documents from Index).
