Multiple search criteria on one field

@operator

Is it possible to have multiple search criteria on one field?

I have a customized text area field on an inventory item field and I'd like to perform a search with multiple criteria on this field.  The criteria are:

[LIST=1]
[*]It cannot be empty.
[*]It cannot begin with "DONE".
[/LIST]

This is an attempt to recreate a web-based saved search with web services. 

My code is as follows:

 ItemSearch itmSearch = new ItemSearch();  ItemSearchBasic itmSearchBasic = new ItemSearchBasic();    SearchStringCustomField notEmpty = new SearchStringCustomField();  SearchStringCustomField notDone = new SearchStringCustomField();    notEmpty.internalId = "custitem46";  notDone.internalId = "custitem46";    notEmpty.@operator = SearchStringFieldOperator.notEmpty;  notEmpty.operatorSpecified = true;    notDone.@operator = SearchStringFieldOperator.doesNotStartWith;  notDone.searchValue = "DONE";  notDone.operatorSpecified = true;    itmSearchBasic.customFieldList = new SearchCustomField[] { notEmpty, notDone };  itmSearch.basic = itmSearchBasic;    SearchResult response = netSuiteService.search(itmSearch);
