Hey Arnold,


*Now I want to clear any existing ranks before updating with new ones,
without having to query what they are first.*

Reading the answer of your question, it seems that there are no inbuilt
functionality of Solr. Having support of wildcards while indexing could be
a nice feature. JIRA?

Anyways, since I'm off to home for Diwali and cannot experiment stuff on my
PC, here are some possible workaround:

- If you know exactly the universal set of field rank_* as they add up, you
could add these in a list. While you atomic update the newer docs, you can
first post a doc that sets all of these fields to null. This could not be
exactly what you are looking for but this is certainly faster than
querying. I had used a similar solution to handle not having duplicate
values in a field.

- Can we use a copyField, which copies catchallrank to all rank_*, here? If
this is possible, we can post null to catchallrank field before we index
newer docs. I don't know how copyField works with atomic updates. I'll
surely try this when I get back to Indiamart.
