Ah, I see. This is a bit lower level than I was thinking. Still useful, but
different. I was thinking about having PreAnalyzedField extend directly from
TextField rather than from FieldType, and then be able to build up whatever
analysis chain that you want in the usual TextField sense. Query analysis would
proceed as with a normal TextField, but index analysis would smart detect
whether this input was already parsed or not. If the input was not parsed, then
it would go through the normal analysis. On the other hand, if the input was
already parsed, then the token stream would go straight into the index (the
assumption being that someone upstream understands what they're doing).
This way, in the SolrJ client you could build up some extra functionality so
that the PreAnalyzedTextFields would be parsed client side and sent to Solr. In
my current application, we have one Solr and N-indexers on different machines.
The setup described here would take a big load off of Solr. The other benefit
of this setup is that query analysis proceeds as it always does. I don't
understand how someone would search over a PreAnalyzed field as it currently
stands, without a bit of extra work/custom code on the client.
One pitfall to my idea is that you'd have to create a similar
PreAnalyzedIntField, PreAnalyzedLocationField, PreAnalyzedDateField etc. I wish
Java had mixins or multiple inheritance.

> PreAnalyzed field extends plain FieldType and mistakenly uses the
