Hi David, thanks for replying, The field boost attribute was put there by me back in the 1.3 days, when I somehow gained the mistaken impression that it was supposed to work! Of course, despite a lot of searching I haven't been able to find anything to back up my position ;)
Unfortunately our code (intentionally) has no idea what index it is writing to so only a schema-based approach is really going to work for us. Of course, by now I am convinced that this might be a really good feature - I might get the chance to look into it in the near future - can anyone think of reasons why this might not work in practice?

The "boost" attribute goes on the field for the XML message you're sending to Solr. In your example you mistakenly placed it in the schema. FYI I use index time boosting as well as query time boosting. Although index time boosting isn't something I can change on a whim, I've found it to be far easier to control the scoring than say function queries which would be the query time substitute if the boost is a function of particular field values. ~ David Smiley Author: http://www.packtpub.com/solr-1-4-enterprise-search-server/ On Nov 18, 2009, at 6:40 AM, Ian Smith wrote: > I have the following field configured in schema.xml: > > <field name="title" type="text" indexed="true" stored="true" > omitNorms="false" boost="3.0" /> > > Where "text" is the type which came with the Solr distribution.
