Re: It is not possible to define "@FullTextFilterDef" filters. ( https://hibernate.atlassian.net/browse/HSEARCH-3862?atlOrigin=eyJpIjoiMDFkMjBkNmY4MDI0NDQxYjkxNTAxNzc5N2YzNGQyODQiLCJwIjoiaiJ9 )

I think that it would be easy to open such functionality is building a filter factory as a fragment of a predicate.

public static class TestFilterFactory implements FilterFactory {

	@Override
	public SearchPredicate create(FilterFactoryContext ctx) {
		SearchPredicate filter = ctx.predicate()
			.match().field( "fieldName" )
			.matching( ctx.param( "match" ) )
			.toPredicate();
		return filter;
	}
}

Such a filter could be, like in the previous version, declared using annotations.

@FullTextFilter(name= "test_filter" , factory = @FilterFactoryRef(type = TestFilterFactory.class))
public class Assortment implements Serializable {
....

Later, you could use such a filter when creating a query.

	scope.query()
	.where( f -> {
		return f.bool()
			.filter( f.def( "match_fieldName" ).param( "match" , true ) );
	}).toQuery()

I think that this functionality would be very simple to implement in the current code.
