Hello!

I have a table with several textfields. I want to make a search for posts where ANY of the textfields match a given text. Is there a simple way to do this?

That's supported since v2.5, you can specify multiple fields in the FieldCompareFullTextSearch predicate. (for sqlserver2005 and up).

public FieldFullTextSearchPredicate(IList entityFields, FullTextSearchOperator operatorToUse, string pattern) 

Example:

PredicateExpression.Add(new FieldFullTextSearchPredicate(
    new IEntityField2[] { CustomerFields.CompanyName, CustomerFields.ContactName},
    FullTextSearchOperator.Contains, "XYZ"));

You can also use OR-ed FieldLikePredicate expressions.
