minh truong created SOLR-11236: ---------------------------------- Summary: Facet allow paging and make bucketSizeLimit as optional parameter Key: SOLR-11236 URL: https://issues.apache.org/jira/browse/SOLR-11236 Project: Solr Issue Type: New Feature Security Level: Public (Default Security Level. Issues are Public) Components: streaming expressions Affects Versions: 6.6 Reporter: minh truong
FacetStream in streaming expression do not have paging capability and do not have the ability to retrieve all the facet. To resolve the bucketSizeLimit to be optional: 1. The "\lucene-solr\solr\solrj\src\java\org\apache\solr\client\solrj\io\stream\FacetStream.java" the constructor with StreamExpression parameters, comment out the checking of limit must be greater zero and when it is exception assign a negative value to bucketSizeLimit. 2. The method read() update the logic to "if(index < tuples.size() && (index < bucketSizeLimit || bucketSizeLimit <= 0))" To add paging to facetStream: 1. create a private variable call startAt as int (dafault 0). 2. retrieve the value from StreamExpression variable and start the value to startAt. 3. overwrite the method writeMap from tupleStream and in the method in the try catch before the for loop. Set index with startAt and set bucketSizeLimit to bucketSizeLimit plus startAt if(bucketSizeLimit is a positive integer). -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
