Solr really isn't organized for tree structures of data. I think you
might do better using a database with a tree structure.
pojo would be a table of pojo's serialized out. And the parent_id
could point to another structure that builds the tree. Can you flesh
out your use case more of why they need to be in a tree structure.

Hi Eric,
Thanks for your response.
Yes you are right! Am trying to place POJOs into Solr directly and
this is
working fine.
I want to search them based on the object properties, need to
organize
them in a heirarchy but not by package names.
Something like:
/Repository
|
|_ Folder1
|
|_ POJO 1
It must store the object in this hierarchy. I might be asking which
is not
at all supported by Solr.
Please give your valuable inputs.

Praveen

Are you trying to Java objects in Solr in order to be searchable?
How
about just dumping them as text using POJO <--> to text formats such
as JSON or Betwixt (http://commons.apache.org/betwixt/).
Then you can just search on the package structure...
?q=com.abc.lucene.* to return everything under that structure?

Hi
I just upload simple POJOs into Solr by creating custom types and
dynamic
fields in Solr schema as shown below,
....
...
<fieldType name="TestType" class="com.abc.lucene.TestType"
sortMissingLast="true" omitNorms="true"/>
....
<dynamicField name="*_i_i_s_m" type="integer" indexed="true"
stored="true" multiValued="true"/>
<dynamicField name="*_i_i_s_nm" type="integer" indexed="true"
stored="true" multiValued="false"/>
<dynamicField name="*_i_i_ns_m" type="integer" indexed="true"
stored="false" multiValued="true"/>
....
But I need to organize these POJOs in a hierarchy which can be
navigated
easily (something like explorer).
Am not sure whether this feature is supported by Solr. But still
planning
to implement it somehow (With the help of DB).
/Root
|
|_ POJO Type1
| |
| |_POJO Type1_1
|
|_POJO Type2
|
|_POJO Type2_1
I need to organize the POJOs as shown above.
Is there any way to achieve this requirement??

Praveen
