RegexTransformer: sourceColName version not handling multiValued fields
correctly
---------------------------------------------------------------------------------
Key: SOLR-1498
URL: https://issues.apache.org/jira/browse/SOLR-1498
Project: Solr
Issue Type: Bug
Components: contrib - DataImportHandler
Affects Versions: 1.4
Environment: Windows XP, JDK 6, Tomcat 6
Linux (RedHat), JDK, Tomcat 5
Reporter: Chantal Ackermann
Versions in use/compared:
Solr 1.3
(Nightly 5th August)
Nightly 22nd September
As RegexTransformer is not different between the two nightlies, the
issue probably appeared before.
ISSUE:
Using RegexTransformer with the 'sourceColName' notation will not populate
multiValued (actually containing multiple values) fields with a list but
instead add only one value per document.
The version with 'groupNames' does.
worked for 1.3 (regression):
<field column="participant" sourceColName="person" regex="([^\|]+)\|.*" />
<field column="role" sourceColName="person"
regex="[^\|]+\|\d+,\d+,\d+,(.*)" />
works for nightly 22nd Sept:
<field column="person" groupNames="participant,role"
regex="([^\|]+)\|\d+,\d+,\d+,(.*)" />
(Both fields are of type solr.StrField and multiValued.)
Comparing the source code of RegexTransformer 1.3 vs. 22nd Sept, I found:
for (Object result : results)
row.put(col, result);
(lines 106-107 of transformRow() 22nd of Sept)
