Index time boosting with DIH
Can someone point me to an example for using index time boosting with the DataImportHandler.

Thanks for the answer.
I want to share the configuration that worked for me (see the follow up question at the end):
(Boosting a document on the basis of a field value at index time.)
It took me some time to figure out, that for the row.get to work, I had to use the column name (the one in the select list) whereas for a put the fieldname (or pseudo fieldname) is working.
<dataConfig>
<dataSource .../>
<script><![CDATA[
function BoostDoc(row) {
if(row.get('SOME_COLUMN') == 'someValue') {
row.put('$docBoost', 20);
}
return row;
}
]]></script>
<document name="mydoc">
<entity name="myentity"
transformer="script:BoostDoc"
query="select ...">
<field column="SOME_COLUMN" name="someField" />
...
A follow-up question:
This is only working for non-wildcard queries for me (StandardRequestHandler as well as edismax)
For wildcard-queries a constant score is returned.
Is there any way to get this setting working for wildcard queries as well?

You can use the special flag variable $docBoost to add a index time boost.
