Alex - that’s definitely possible, with performance being the main consideration here.
But since this is for query time stop words, maybe instead your fronting application could take the users list and remove those words from the query before sending it to Solr? I’m curious what the ultimate goal / use case is for this feature, which may help us better guide you on ways to do what you need. — Erik Hatcher, Senior Solutions Architect http://www.lucidworks.com <http://www.lucidworks.com/> > On Mar 27, 2015, at 8:32 AM, Alex Sylka <sylkaa...@gmail.com> wrote: > > We need advanced stop words filter in Solr. > > We need stopwords to be stored in db and ability to change them by users > (each user should have own stopwords).
