> Project: Solr
> Issue Type: Improvement
> Components: search
> Affects Versions: 4.0-ALPHA
> Reporter: Jamie Johnson
>
> The original DisMaxQParser seems to have support for handling multiple
> aliases so someone could do query rewrite on more than just the default
> field. If the ExtendedDisMaxQParser supported this and exposed this
> capability we'd be able to build more powerful rewrite capabilities such that
> could reduce the size of an index. For instance say we have a scenario where
> we have 3 fields first_name, last_name and name. In this situation we don't
> completely control the input, we may have first_name and last_name or just
> name. In this case given 2 documents as follows:
> Doc 1
> first_name: John
> last_name: Doe
> Doc 2
> name: Jane Doe
> if the user did a query on name:Doe we would be able to rewrite the query to
> return both documents such that the query would be name:Doe OR first_name:Doe
> OR last_name:Doe
