Brilliant, thanks Andrew. There's quite a good chance that we'd be in a position to affect a change across the board, as the instance in question covers a single user base and content type.</div>

<p>You cannot specify qf in an API search. Instead, its value is hardcoded here:</p>
<p><br>
</p>
<p><a class="x_moz-txt-link-freetext" href="https://github.com/archivesspace/archivesspace/blob/master/backend/app/model/solr.rb#L278">https://github.com/archivesspace/archivesspace/blob/master/backend/app/model/solr.rb#L278</a><br>
</p>
<p><br>
</p>
<p>A few lines further down you can see where it calls hooks, which can be set up in plug-ins. So you can override the qf that way, but doing so will apply to all searches everywhere (in the public user interface and staff interface) not just specific API calls.
Alternatively, it might be possible to write a plugin to create a new endpoint to allow dynamic setting qf, if it is crucial for your use-case.<br>
</p>
<p><br>
</p>
<p>Some Solr parameters have equivalents in the ArchivesSpace API, which are listed here:</p>
<p><br>
</p>
<p><a class="x_moz-txt-link-freetext" href="https://archivesspace.github.io/archivesspace/api/#search-this-repository">https://archivesspace.github.io/archivesspace/api/#search-this-repository</a></p>
<p><br>
</p>
<p>For example, instead of fl there is the fields[] parameter. And, although it is missing from the documentation, you can do fq, except it is renamed filter_query[]. The defType is already set to edismax. Instead of rows you have to use page_size, but if you
want 1000 hits per page then you need to change AppConfig[:max_page_size] in config.rb.<br>
</p>
<p><br>
</p>
<p>The summary field can be set to indexed="true" in schema.xml. I've done so myself, but on a system that uses an external Solr server, with its own schema.xml. In a system running from a built release, and using internal Solr, schema.xml is inside a .war
file.<br>
