Sylvain Vieujot commented on HSEARCH-1065:
------------------------------------------

Thank you for the comment.

I can live with that for searches on a single field, as it can easily be dealt with progamaticly.
However, for seaches on multiple fields, this is a real inconvenience :

ftem.getSearchFactory()
	.buildQueryBuilder()
	.forEntity( TestEntity.class )
	.get()
	.keyword()
	.fuzzy()
	.onFields( "text", "testEnum" ) // CRASH HERE
	.matching( "Sample" )
	.createQuery();

I think the novice understanding is that a full text search matching method should always accept a String.
Otherwise, it makes searh form parameter processing quite cumbersome.
