HeXin commented on SOLR-5198:
-----------------------------
hi, Shawn, you are right.
But i think you have written the class BM25SimilarityFactory at first and maybe
its function just to provide BM25Similarity as default similarity.
Maybe i have not describe the feature clearly. I just want the two scenarios
below can be done just through modifying schema.xml.
1. If we want to use a different default similarity rather than
TFIDFSimilarity.
2. If we want to do per-field support and make BM25Similarity as default
similarity for the fields which not configure similarity.
I think we can support it without any custom code.
> Make default similarty configurable

> URL: https://issues.apache.org/jira/browse/SOLR-5198
> Project: Solr
> Issue Type: Improvement
> Components: Schema and Analysis
> Affects Versions: 4.4
> Reporter: HeXin
> Priority: Minor
> Fix For: 4.5, 5.0

>
> Though the code has supported for customizing scoring on a per-field basis
> in using <similarity/> in a schema's fieldType and
> we can configure our custom similarity factory in schema, we can't configure
> the default similarty and it is hardcode in SchemaSimilarityFactory.
> If we want to use another similarity as default similarty instead of
> DefaultSimilarity provided by lucene, we must to write another similarity
> factory to do this. Therefore, it is necessary to make default similarty
> configurable.
> Any comments is welcomed.
