[hibernate-dev] Search 5 migration pains: MultiFieldQueryParser and Numeric Fields

[Sanne Grinovero]

As reported on SO [1], it's not a straight forward migration for those
who embraced the convenience of using a MultiFieldQueryParser, or one
of the other Lucene provided parsers.

In the specific example, I think the right answer would be to use the
programmatic API or our DSL.. but let's consider the use case in which
you want to parse user input, from a text input in your application?

Using the parser is quite convenient in such a case, as people can
express boolean operators and field names, while keeping the UI very
simple.

Wouldn't it be nice to have a custom "parser" in our DSL, which
essentially mimicks the functionality of the MultiFieldQueryParser but
takes advantage of our indexing metadata - like we do for the HQL
Parser?
