hello all,

can i use the technique described on the wiki at:

http://wiki.apache.org/solr/SolrRelevancyFAQ#index-time_boosts

if i am populating my core using a DIH?

looking at the posts on this subject and the wiki docs - leads me to believe
that you can only use this when you are using the xml interface for
importing data?

thank you

See http://wiki.apache.org/solr/DataImportHandler#Special_Commands and the $docBoost pseudo-field name.

thanks for the reply,

so to use the $docBoost pseudo-field name, would you do something like below
- and would this technique likely increase my total index time?

<dataConfig>
  <dataSource .../>
                
 
  <document name="mydoc">
    <entity name="myentity"
            transformer="script:BoostDoc"
            query="select ...">
    
     <field column="SOME_COLUMN" name="someField" />
     ...

You need to add the $docBoost pseudo-field to the document somehow.  A transformer is one way to do it.  You could just add it to a SELECT statement, which is especially convienent if the boost value somehow is derrived from the data:

SELECT case when SELL_MORE_FLAG='Y' then 9999999 ELSE null END as '$docBoost', ...other fields... from some_table, etc

Either way I wouldn't expect it to make the indexing be noticably slower.

thank you james for the feedback - i appreciate it.

ultimately - i was trying to decide if i was missing the boat by ONLY using
query time boosting, and i should really be using index time boosting.

but after your reply, reading the solr book, and looking at the lucene dox -
it looks like index-time boosting is not what i need.  i can probably do
better by using query-time boosting and the proper sort params.

thanks again
