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.
Much appreciated Scott ========== Scott Renton Digital Library Development & Systems Floor F East Argyle House 515219 ________________________________ From: [email protected] <[email protected]> on behalf of Andrew Morrison <[email protected]> Sent: 23 August 2021 13:30 To: [email protected] <[email protected]> Subject: Re: [Archivesspace_Users_Group] SOLR/API differences This email was sent to you by someone outside the University. You should only click on links or attachments if you are certain that the email is genuine and the content is safe. Sorry, forgot to mention, qf can be set in AppConfig[:solr_params] in config.rb, but again it applies to all searching, not just API searches. Andrew.

Sorry if I gave you the wrong impression in previous emails. You cannot specify qf in an API search. Instead, its value is hardcoded here: https://github.com/archivesspace/archivesspace/blob/master/backend/app/model/solr.rb#L278 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. Some Solr parameters have equivalents in the ArchivesSpace API, which are listed here: https://archivesspace.github.io/archivesspace/api/#search-this-repository 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. 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. Andrew.

Here, I'm trying to use edismax and qf to limit the fields I'm looking in for a term, so we don't get unwanted content coming through: [base_url]/collection1/select?q=joke&fq=types%3Aarchival_object&rows=1000&fl=title+notes+summary&wt=json&indent=true&defType=edismax&qf=notes%5E300+title%5E100&stopwords=true&lowercaseOperators=true<http://lac-archivesspace-live2.is.ed.ac.uk:8090/collection1/select?q=joke&fq=types%3Aarchival_object&rows=1000&fl=title+notes+summary&wt=json&indent=true&defType=edismax&qf=notes%5E300+title%5E100&stopwords=true&lowercaseOperators=true> That does seem to work. When I drop it into the API, though, I notice that fq is ignored (I just move the types into the q, that's ok), fl is ignored (this was just to see things easily, not a big deal), and even with defType=edismax, the all-important qf is ignored. Is that what we'd expect? My GET looks like this (I took the weightings off the qfs): [base_url]/repositories/2/search?q=joke AND types:archival_object&rows=1000&fl=title+notes+summary&wt=json&indent=true&defType=edismax&qf=notes+title&stopwords=true&lowercaseOperators=true&page=1 I was under the impression the API and SOLR syntax were interchangeable, but perhaps not? I've also noticed that I cannot use summary for qf in SOLR. I think this is because it is indexed="false" in schema.xml. Is it likely to be safe to change that and reindex?
