-----------------------------------------
David, thanks for explaining - I see your point, and I like it too.
bq. It needs to examine the field value: if it's "Field" then it gets added
right to the document.
Even if we push this functionality to an UpdateRequestProcessor it still needs
to know when (not) to convert the input String to a Field. Do you have some
thoughts about this?
In UpdateRequestProcessor we deal with SolrInputDocument-s in the context of
available schema and solrconfig - so there are a few options how to determine
the need for conversion.
# It could be based on the document itself (tricky, in the light of multiple
serialization formats).
# OR, we could extend SolrInputField (and the document serializations) to
support additional per-field flags to indicate this, but that would complicate
matters even more.
# OR, if this decision is going to be based on schema we would have to extend
schema to pass additional flags to mark fields as preanalyzed - also tricky.
# And finally, we could put the list of fields to always convert in the init
args of this UpdateRequestProcessor in solrconfig ... but that's a bit ugly,
mixing schema and solrconfig.

> PreAnalyzed field extends plain FieldType and mistakenly uses the
> DefaultAnalyzer as query analyzer, and doesn't allow for customization via
> <analyzer> schema elements.
> Instead it should extend TextField and support all query analysis supported
> by that type.
