Jack Krupansky commented on SOLR-3442:
--------------------------------------
Maybe Solr has outgrown the concept of a single example schema/config. "Full
function" and "maximal performance" conflict to some degree and picking one
arbitrary point on the design spectrum does a disservice for those who have
varying requirements. The current example already has performance tips and a
warning advisory not to use it for benchmarking. And SolrCell documents having
"core", common metadata is somewhat distinct from full-custom schema design.
The copyField to "text" pattern is more clearly targeted at non-dismax users,
where "text" is the single default search field.
This issue essentially raises the question: Is non-dismax query parsing dead?
If not, the copyField/text pattern still seems relevant.
Maybe it would be worth having a modest library of schema/config files that the
user can select from when running "example". OTOH, maintaining a lot of
somewhat similar files can be a pain. A way to configure the schema/config
files (conditionals) would be helpful.
