OK . That is not a good solution.
In Solr, you can only have a flat document structure. Where each field
is a primitive (String, Number, Date) or a List of primitives.So, the
SolrJ API only supports these . You may really not need a Custome
type.

Re: Composite POJO support
Posted by Praveen Kumar Jayaram <Pr...@gmail.com>.
Hi Noble,
Storing fields as Strings means I have to use a POJO for this activity
right? If so I am done.
But according to your suggestion "Let the FieldType in Solr parse and create
appropriate data structure".
How am I going to do this? Am very new to Solr. So please don't mind if I
dumb questions.
Please give some sample example if possible.

The POJO is a client side Object. It is converted to xml before
POSTING the data to Solr. The client side code is totally agnostic of
the field type in Solr schema.

What you can do is to write your field value as one String. Let the
FieldType in Solr parse and create appropriate data structure.

Re: Composite POJO support
Posted by Praveen Kumar Jayaram <Pr...@gmail.com>.
Thanks for the reply Noble Paul.
In my application I will be having multiple types of object and the number
of properties in each object will vary.
So I have made them as FieldType and defined in schema.xml also
How do I store the POJO without declaring it as a FieldType?
Solr needs to recognize a type right?

Re: Composite POJO support
Posted by Noble Paul നോബിള് नोब्ळ् <no...@gmail.com>.
why is the POJO extending FieldType?
it does not have to.
composite types are not supported.because Solr cannot support that.
But the field can be a List or array.
