Sanne Grinovero commented on HSEARCH-477:
-----------------------------------------
I assume there might a need to define the order in which TokenFilter(s) and CharFilter(s)
are applied?
Maybe filters should be made of type Object, not nice for typesafety and
self-documentation, so that it could contain both types.
Support for the new Solr's character filters
--------------------------------------------
Key: HSEARCH-477
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-477
Project: Hibernate Search
Issue Type: Improvement
Components: analyzer
Reporter: Gustavo Fernandes
Priority: Minor
Attachments: solr14-2.patch
Solr 1.4 introduced CharacterFilters [1], which are based on Lucene's CharStream.
Those filters are currently incompatible with the annotation @TokenFilterDef, which accept
only TokenFilterFactories:
{code}
public @interface TokenFilterDef {
public abstract Class<? extends TokenFilterFactory> factory();
public abstract Parameter[] params() default { };
{code}
Onde ideia is to keep the same annotation, "generalize" the token filter
factory type in the annotation, and on SolrAnalyzerBuilder construct a TokenizerChain
which will accept both type of filters [2]
