What I'm after is to restrict the 'whole' index through a set of unique keys. Each unique key set is likely to have between 100 & 10000 keys and these sets are expected to be different for most of the queries. I'm trying to see if I can achieve a generic 'fk' (for filter key) kind of parameter so this could be applied to 'any' RequestHandler.
To keep the filter-queries functionality (as a List<Query>), I compute a DocSet by using my 'unique key filter docset' as a base and iteratively 'and' it with the filter-queries executed through SolrIndexReader.getDocSet(Query, DocSet). The other way could be creating a BooleanQuery that 'ands' TermQueries built from the unique key set; I might still revert to that since my current code needs a small patch in SolrIndexReader (flags in getDocList). In SolrIndexReader , if getDocListAndSet & getDocList were to accept a DocSet filter plus the List<Query>, I'd use those but I had to choose whether I use a List<Query> OR a DocSet as filter. I might have missed something, the code being quite dense: the equivalent signatures I could manage to get are: public DocList getDocList(Query query, DocSet filter, Sort lsort, int offset, int len, int flags) throws IOException; and public DocListAndSet getDocListAndSet(Query query, DocSet filter, Sort lsort, int offset, int len, int flags) throws IOException; It seems to work, I dont know if it is efficient cache wise & al.
