addAlias(String field,

Add an alias to this query parser.

getFieldQuery(String field,
String queryText,
boolean quoted,
boolean raw)
Delegates to the super class unless the field has been specified
as an alias -- in which case we recurse on each of
the aliased fields, and the results are composed into a
DisjunctionMaxQuery.
