> The programmatic API provides the ability to specify an analyzer on an entity class bridge (ClassBridgeMapping), but during initialization, an exception is thrown.  See below for an example search mapping, exception stack trace, and the diff for my fix.
> I modified the Hibernate Search code by copying the analyzer initialization code from the creation of fields into the creation of class bridges.  It appears that there may be other attributes that are not being properly processed for class bridges, but this fix solves my immediate problem.
> Here is an example:
> {code}
>         SearchMapping searchMapping = new SearchMapping();
>         searchMapping
>         	.analyzerDef("customanalyzer", StandardTokenizerFactory.class)
>         		.filter(LowerCaseFilterFactory.class)
>         		.filter(NGramFilterFactory.class)
>         			.param("minGramSize", "3")
>         			.param("maxGramSize", "3")
>         	.entity(Person.class)
>         		.classBridge(NameAppendingBridge.class)
>         			.name("fullName")
>         			.analyzer("customanalyzer")
>         			.index(Index.YES)
>         			.store(Store.YES)
>         			.param("fields", "frstName,othrName,lastName,mdnName")
>         		.indexed()
> ...
