multiple attribute

[Michael Jones <mi...@gmail.com>]

Hi,

I know that solr doesn't provide support for nested documents, but can I
add multiple attributes to a field?

<add>
<document>
<field name="test" foo="one" bar ="two" index="true">

And specify an index on those attributes?

I have a nested document that needs to be saved and searched.

If the above can not be achieved what would be a suitable alternative?

Would I have to do something like:

<add>
<document>
<field name="test" foo="one" bar ="two">
<field name="foo" index="true">one</field>
<field name="bar" index="true">two</field>

And just return name="test" ?

Thanks

Hi,

Sorry if anyone found my question confusing.

I have an XML document that is nested

<file>
 <foo>
  <bar/>
  <thunk/>
 </foo>
</file>

And I know that with solr that you have to flatten your data, so I was just
trying to workout the best way to do a search on nested document. I was
looking to see if instead of having multiple nodes, I would have those
nodes as attributes on one single node and still be able to search.
So if my node looked like <field name="person" date="2000-01-01"
location="earth" username="bob" job="test" index="true" />

I would be able to search: date < 2002 & location = earth & job = test

But I'm not sure if that is the best way to do it? I know I would have to
specify a type for each attribute in the config.

Michael,

Your question is a little bit confusing. Business entities have attributes.
We model entities as documents, and attributes as fields. That's why adding
attributes to a filed is contradictory. Btw there few nearby conceptions in
Lucene, which are Payloads and TermsPositions.
About the problem itself I can suggest:

   - http://wiki.apache.org/solr/Join
   - http://wiki.apache.org/solr/FieldCollapsing - it supports faceting
   - block join
   http://blog.mikemccandless.com/2012/01/searching-relational-content-with.html
   https://issues.apache.org/jira/browse/SOLR-3076 - patch only but really
   performant
   - http://wiki.apache.org/solr/SurroundQueryParser available in 4.0 can
   be used by the way proposed here http://goo.gl/R2bxc video
   http://vimeo.com/album/2012142/video/33817062

Have a good dive!
