In android I am using the following statement.
model = dataHelper.rawQuery(\"SELECT _id, engword, lower(engword) as letter FROM word WHERE letter >= \'a\' AND
The right statement is :
model = dataHelper.rawQuery(" SELECT _id, engword, lower(engword) as letter FROM word W HERE letter >= 'a' AND letter < '{' AND engword LIKE ? ORDER BY engword ASC ", new String[] {"%" + filterText + "%"} );
