Javadoc search: there are issues with generics in parameters

To reproduce open http://cr.openjdk.java.net/~anazarov/scratch/javadoc-search/overview-summary.html

1. type in: "ClassSimple0(int, Map,"
    found nothing, but there is constructor ClassSimple0(int, Map, String)
2. type in: "ClassSimple0(int, Map<"
    you will see "sampleapi.pkg3.ClassSimple0.ClassSimple0(int, Map<String, String>, String)" it's ok. Now add "S" and fully "ClassSimple0(int, Map<S"
   drop down list will contain "...ClassSimple0(int, Maptring, String>, String)"
