Custom Match Algorithm fails when no weighting possible

[masyukun]

We have a custom match algorithm that generates a cts:query value of type cts:document-query, and though the document exists, and we can run the boost-query successfully in isolation, the matching code never comes back with the specified URI as a valid match.

We believe this is because cts:document-query does not have a "weight" option, so it's filtered out of the score generation code.

Please modify the Matcher so that it allows cts:query components without weight components to still contribute to the match score. Possibly we need to not rely on the built-in weighting system.
