Re: Exception: null: java.lang.NullPointerException when use simpleQueryString() ( https://hibernate.atlassian.net/browse/HSEARCH-3844?atlOrigin=eyJpIjoiNDIzNzIwMzMzZWZlNDI5Yjg1MzAxZTQ2NWM2MDFlZjIiLCJwIjoiaiJ9 )

You are mixing two approaches here, which may be the reason you're getting this exception.

*Step objects, like the one you're storing in the "select" and "sort" variables, are not meant to be passed around at all. For that, you should call toPredicate() / toSort() etc. and then you will get a SearchPredicate / SearchSort /etc. that you can safely pass around and even re-use.

Try this:

    if (searchFullText != null ) { select = scope.predicate().simpleQueryString() .field( "shoppingName" ) .matching(searchFullText) .defaultOperator(BooleanOperator.AND).toPredicate(); }

   else { select = scope.predicate().matchAll().toPredicate(); }

   SearchQuery<Assortment> query = session.search(scope)
   .where(select)
   .sort(sort).toQuery();

or this:

   
   SearchQuery<Assortment> query = session.search(scope)
   .where(f -> {
       if (searchFullText != null ) { return f.simpleQueryString() .field( "shoppingName" ) .matching(searchFullText) .defaultOperator(BooleanOperator.AND); }
       else { return f.matchAll(); }
   } )
   .sort( f -> ... ).toQuery();
