Comment 18 for bug 1849212

It occurs to me that rather than implementing the bib search restriction as a facet, it could be done as a search filter along the lines of site() or badge_orgs() or copy_tag(). This would entail updating OpenILS/Application/Storage/Publisher/metabib.pm and OpenILS/Application/Storage/Driver/Pg/QueryParser.pm to recognize the filter and generate SQL to add conditions on the core bib search query. It could also be done as a search modifier similar to #available or #lucky.

Either way, this would eliminate any need for a custom Boolean facet type or changes to the bib ingest mechanism. I don't think it would be particularly time-consuming to implement.

I suggest going for a search filter along the lines of on_reserve(ORG[, ORG2, ORG3...]) rather than just a search modifier, as it might be handy to be able to directly specify that you're looking for items that are on reserve at a given OU or set of OUs. However, it could be done as a search modifier, in which case the user would be relying on site() to scope the search to the desired OUs.
