Subject [jira] Commented: (LUCENE-1749) FieldCache introspection API
Date Sun, 02 Aug 2009 03:28:24 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-1749?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12737984#action_12737984

Mark Miller commented on LUCENE-1749:
-------------------------------------

bq. I was a bit hazy on explain, so for some reason I had it in my head that you would have
to combine the explanations from multiple subreaders

bq. but it would probably break more than it helped right now (by exposing more limitations)
- for example idf in TermWeight.explain()

To be a little more clear - this was originally why I went the direction I did - I assumed
the reader was being used for stats that needed to come from the top level reader. Gut reaction
seeing it go into scorer. I hadn't really checked that, at least for these queries, that wasn't
the case - they just use it for the filter/fieldcache.

> FieldCache should expose an Expert level API for runtime introspection of the FieldCache
to provide info about what is in the FieldCache at any given moment.  We should also provide
utility methods for sanity checking that the FieldCache doesn't contain anything "odd"...
>    * entries for the same reader/field with different types/parsers
>    * entries for the same field/type/parser in a reader and it's subreader(s)
>    * etc...
