Hi Dennis, thank you for your answer, but didn't understand why you say it doesn't need serialization. I'm with the option "C". but the main question is, how to put into one field a result of many fields: "SELECT * FROM".
thanks, Rich -----Original Message----- From: Dennis Gearon [mailto:gear...@sbcglobal.net] Sent: Monday, January 24, 2011 02:07 To: solr-user@lucene.apache.org Subject: Re: DIH serialize Depends on your process chain to the eventual viewer/consumer of the data. The questions to ask are: A/ Is the data IN Solr going to be viewed or processed in its original form: -->set stored = 'true' --->no serialization needed. B/ If it's going to be anayzed and searched for separate from any other field, the analyzing will put it into an unreadable form. If you need to see it, then --->set indexed="true" and stored="true" --->no serializaton needed. C/ If it's NOT going to be viewed AS IS, and it's not going to be searched for AS IS, (i.e. other columns will be how the data is found), and you have another, serialzable format: -->set indexed="false" and stored="true" -->serialize AS PER THE INTENDED APPLICATION, not sure that Solr can do that at all.

D/ If it's NOT going to be viewed AS IS, BUT it's going to be searched for AS IS, (this column will be how the data is found), and you have another, serialzable format: -->you need to put it into TWO columns -->A SERIALIZED FIELD -->set indexed="false" and stored="true" -->>AN UNSERIALIZED FIELD -->set indexed="false" and stored="true" -->serialize AS PER THE INTENDED APPLICATION, not sure that Solr can do that at all.

I'll use the value in PHP - I don't know if it is possible to serialize in PHP style at all. This is what I tried and works with a given factor: in schema.xml: <field name="main_timetable" type="text" indexed="false" stored="true" multiValued="true" /> in DIH xml: <dataConfig> <script><![CDATA[ function my_serialize(row) { row.put('main_timetable', row.toString()); return row; } ]]></script> . <entity name="main_timetable" query=" SELECT * FROM shop_time_table stt WHERE stt.shop_id = '${shop.id}';" transformer="script:my_serialize" > . > Can I use java directly in script (<script language="Java">) ? How could I achieve this? Or any other idea? I need these values together (from a row) and I need then in PHP to handle the result easily. thanks, Rich __________ Information from ESET NOD32 Antivirus, version of virus signature database 5740 (20101228) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com __________ Information from ESET NOD32 Antivirus, version of virus signature database 5740 (20101228) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
