Thanks for your reply Shawn. The query elevation worked for us. I have
another question though. Right now I have ways to handle specific queries in
the elevate.xml. The concern I am having is that I may have hundreds of
queries that need to return different pages first. Is the only way to do
this via the elevate.xml or is there a better approach for instance boosting
fields ? When I am boosting fields in this fashion it is not working for me
:

<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
<str name="defType">edismax</str>
<str name="qf"> url^50 host^30 content^20 title^10</str>
</lst>
<arr name="last-components">
<str>elevator</str>
</arr>
</requestHandler>


Thanks for your help .

people in which case I want the URL to their landing page returned first. I
have configured the dismax query parser in my solrconfig but it seems that
the boost being applied is arbitrary .

I think there's a fundamental misunderstanding of how "defaults" works.

I have no idea what happens with multiple "q" parameters, which you have
configured in defaults.  I do know that if your request includes a "q"
parameter, then what you've put in defaults for "q" is going to be
overridden and ignored.

This section of the documentation covers defaults, appends, and invariants:

I think the Query Elevation Component might be the kind of functionality
you're after.  What you're trying to do with defaults is NOT going to work.
