I'm very interested in SpanNearQuery, because it allows for quite
powerful phrasal searching.
However, unlike BooleanQuery, there doesn't seem to be any way to have
it search multiple fields.
I thought I might be able to wrap multiple SpanNearQueries, each of them
searching a different field, in an outer SpanOrQuery, but that raises an
exception:
java.lang.IllegalArgumentException: Clauses must have same field.
at
org.apache.lucene.search.spans.SpanOrQuery.addClause(SpanOrQuery.java:63)
So, is there any way to do what I'd like to do? Would it require
performing multiple search operations, once per field, and then
combining the results from those multiple queries?
