Organizing POJO's in a heirarchy in Solr
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??
Regards,
Praveen

Thanks for your response Eric.
Actually the scenario is to use the Solr search server as a hierarchical
storage system also. Where we store objects/files in a hierarchy and do
searches on that. something like DB (for files) + Solr.
Here I am evaluating Solr with an knowledge management system.
So thought of storing in a hierarchy.

Thanks for your response Eric.
I appreciate your idea to have the path as a property/field itself. Am
pretty new to Solr and Lucene.
Could you please post some good pointers for learning more on Solr?

That's not a very fair statement. Sure, documents in Solr/Lucene are
simply composed of a flat list of fields, but one can store a path-
like representation in a field and search within hierarchies. For
example, indexing a "string" path field with values such as:
path: /Repository/Folder1/POJO1
One could query for /Repository/* to get all documents (err, objects)
from that tree downward, and so on for any sub or complete path.
The main thing to look at when figuring out how to squash a domain
into a Lucene index is what exactly do you need on the querying side
of things, rather than looking at it from a domain model and seeing
how to represent relationships and hierarchy from that perspective.

Re: Organizing POJO's in a heirarchy in Solr
Posted by Schley Andrew Kutz <sa...@gmail.com>.
I like the path idea, however, it does not allow you to perform
tantamount joins on elements in the path. I am working on an idea that
would effectively enable you to perform RDF style queries:
FIND a WHERE a.f1 > 300 AND a.b.f1 > 3 AND a.c.name == 'foo'
f1 is a field on 'a' where 'b' and 'c' are pointers on 'a' to other
documents. Essentially this can be accomplished with facets since you
don't have to retrieve the b and c documents, only whether or not the
set is empty. I am considering doing this as a response writer or a
separate web service, but ideas are welcome.

Re: Organizing POJO's in a heirarchy in Solr
Posted by PKJ <Pr...@gmail.com>.
Pretty good idea David.
Yeah I understand that Solr has not build for such purposes. It is a good
search server.
Will incorporated your idea to store the path as a property and search.
Thanks again. Please post if you see any improvements for this requirement
in near future.

Posted by Erik Hatcher <er...@ehatchersolutions.com>.
Good thinking David! :)
Or even a tokenized field... tokenized by path segments, so the
document we're talking about could have a path field with the terms: /
Repository and /Repository/Folder1 - that way the queries can be made
simpler (and perhaps faster).

Re: Organizing POJO's in a heirarchy in Solr
Posted by "Smiley, David W." <ds...@mitre.org>.
Solr could still work for you Praveen.
Consider a schema with a field named "parentPath" that is not tokenized. It stores the path to the folder containing the current document but does not have the document's name in it. In your example, this would be "/Repository/Folder1/". The document's name would be stored in another field. This system is not perfect but it meets the only requirement you've outlined.

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.

Re: Organizing POJO's in a heirarchy in Solr
Posted by Praveen_Kumar_J <Pr...@gmail.com>.
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.
Regards,
Praveen

Re: Organizing POJO's in a heirarchy in Solr
Posted by Eric Pugh <ep...@opensourceconnections.com>.
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?
