Mark Harwood commented on SOLR-3950:
------------------------------------
bq. If there is some schema config that will tell Solr to do the right thing,
please let me know.
Right now BloomPF is like an abstract class - you need to fill-in-the-blanks as
to what delegate it will use before you can use it at write-time.
I think we have 3 options:
1) Solr (or you) provide a new PF impl that weds BloomPF with a choice of PF
e.g. Lucene40PF so you would have a zero-arg-constructor class named something
like BloomLucene40PF or...
2) Solr extends config file format to provide a generic means of assembling
"wrapper" PFs like Bloom in their config e.g:
postingsFormat="BloomFilter" delegatePostingsFormat="FooPF"
and Solr then does reflection magic to call constructors appropriately or..
3) Core Lucene is changed so that BloomPF is wedded to a default PF (e.g.
Lucene40PF) if users e.g. Solr fail to nominate a choice of delegate for
BloomPF.
Of these 1) feels like "the right thing".
Cheers
