Well, your query below becomes ref_expertise:(nonlinear OR soliton)
AND default_search:"optical lattice:"
The regular Solr/Lucene query should handle pretty much anything you
can throw at it. But do be aware that Solr/Lucene syntax is not true
boolean logic, you have to think in terms of SHOULD, MUST, MUST_NOT.
But this works:
q={!type=edismax qf='name' }(nonlinear OR soliton) AND "optical lattice"
giving this:
+(+((name:nonlinear) (name:soliton)) +(name:"optical lattice"))
