Which stopped working in Solr 8, so we mowed this to solrconfig.xml as: <str name="q.op">AND</str>Now, this search gives 0 results while previously it worked fine and returned 2 records: [ path=select parameters={fq: ["type:Member"], sort: "score desc", q: "u...@gmail.com ad...@yahoo.com", fl: "* score", qf: "email_words_ngram", defType: "edismax", mm: 1, start: 0, rows: 20} ] At the same time the docs say that terms without explicit "+" or "-" are considered as optional and results of both terms should be returned.
Untagged clauses are indeed optional -- if you leave the default operator at "OR". You've set it to "AND", which means that effectively any query clause without a +/- or a boolean operator has an implicit + -- it will be required.
The behavior in Solr 5 should be the same with a default operator of AND, unless you were perhaps running into a bug there. Or maybe everything was not entirely the same before.
Thanks, Shawn
