Re: Order of returned fields

Hi Alex,

Do you think I could then specify an order on the returned fields foreach document, without reordering the fields by parsing the SOLR response ?


Thanks,
Pierre

Hey Pierre,

I don't know if my case helps you, but what I do to keep relational
information is to put the related data all in the same field.

Let me give you an example:

I have a product index. Each product has a list of manufacturer properties,
like dimensions, color, connections supported (usb, bluetooth and so on),
etc etc etc. Each property  belongs to a context, so I index data following
this model:

propertyId ^ propertyLabel ^ propertyType ^ propertyValue

Then I parse each result returned on my application.

Does that help you?

Order matters in my application because I'm indexing structured data -
actually, a domain object model (a bit like with Hibernate Search), only I'm
adding parents to children, instead of children to parents. So say I have
Cities and People, with a 1-N relationship between City and People. I'm
indexing documents for Cities, and documents for People, and the documents
for People contain the fields of the City they're living in.

When I display the results, I'd like the People fields to display before
the City fields. I can parse the Solr response and rearrange the fields (in
the Java middle-tier, or with XSLT, or in the Javascript client), but then I
have to "know" of the domain in too many places. I have to "know" of the
domain in my Java application, in the SOLR schema file, and in the
Javascript that rearranges the fields... I thought maybe I could avoid the
latter and put as much application information as possible in the SOLR
schema, for instance specifiy an order for the returned fields...

Thanks anyway,

Pierre

 Yes, this is normal behavior.

Does order matter in your application?  Could you explain why?

Order is maintained with multiple values of the same field name, though -
which is important.

 Hello,

After a Solr query, I always get the fields back in alphabetical order,
no matter how I insert them.
Is this the normal behaviour?

This is when adding the document...
 <doc>
     <field name="uid">ch.tsr.esg.domain.ProgramCollection[id: 1]</field>
     <field name="genre">collection</field>
     <field name="collection">Bac à sable</field>
     <field name="collection.url">
http://localhost:8080/esg/api/collections/1</field>
 </doc>

... and this is when retrieving it:
     <doc>
         <str name="collection">Bac à sable</str>
         <str name="collection.url">
http://localhost:8080/esg/api/collections/1</str>
         <str name="genre">collection</str>
         <str name="uid">ch.tsr.esg.domain.ProgramCollection[id: 1]</str>
     </doc>

Thanks a lot,
Pierre Auslaender
