| Parameter | Description | ||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Delimiterlist | Specifies delimiters used to separate words. Valid delimiters are:
If delimiterlist is null, a space is used by default. Note: delimiterlist is field mark delimited. | ||||||||||||||||||
| stoplist | No index is maintained for words in the specified stop list. stoplist contains 2 columns. Column 1 is the stop list mode. Use column 2 to specify a user defined stop list (multi-valued column). Note: stoplist is value mark delimited. Available stop list modes are:

Note: If the stop list mode is 2 or 3, then delimit the stop list mode from the stop list values with a field mark. Delimit the stop list values themselves with value marks. See example below.
You can view and modify the default stop list. Use the Environment Index Settings dialog box, reached from the INDEXES... button in the Environment Management dialog box, which is available from the Database-Environment Settings menu, in the Database Manager.
Example
/* code fragment for constructing the stop list before calling Create_Index */ If StopList_NO > 1 then StopList_Text = Trim(Get_Property(Stop_List$, "TEXTVAL")) Swap @tm with @vm in StopList_text If Not(Case_Sens) then Convert @lower.case to @upper.case in StopList_Text End StopList = StopList_No:@fm:StopList_Text End Else Stoplist = StopList_No End Create_Index(Xref_Index$, Filename, Column, Case_Sens, Build_Now, Dlist, StopList)
