Note
	As a rule, a catalog is fully indexed so that no filter rules are required.

If you do not want to index all parts within a catalog, you can define filter rules for this.

Here is an example:

[settings]
GenerationFilterRules=ScriptFilterRule, ScriptFilterRuleErp

[GenerationFilterRule_ScriptFilterRule]
Catalogs=cat/lochplatten_ecat
AlgoTypes=IMG
LineScriptCallbackFile=filter.vbs
LineScriptCallbackFunction=checkLine
IndexTypes=Standard

[GenerationFilterRule_ScriptFilterRuleErp]
Catalogs=cat/lochplatten_ecat
AlgoTypes=IMG
LineScriptCallbackFile=filterErp.vbs
LineScriptCallbackFunction=checkLine
IndexTypes=Erp

Script filter.vbs:

function checkLine(table)
  dim nb = table.selectedRow.getNB()
  checkLine = (InStr(nb, "photo_noerp ") = 0
end function

Script filter_erp.vbs:

function checkLine(table)
  dim nb = table.selectedRow.getNB()
  checkLine = (InStr(nb, "photo_erp ") = 0
end function

	Important
	If checkLine returns true, the line is filtered out, i.e. it is not indexed for the photo search. In this example, all parts contained in the NB photo_noerp and all parts with an ERP number contained in the NB photo_erp would have fingerprints for the photo search.

As an alternative to script callbacks, you can also filter using RegExp:

[GenerationFilterRule_LineFilterRule]
Catalogs=cat/lochplatten_ecat
AlgoTypes=IMG
LineFilterCount=1
LineFilterVar0=NB
LineFilterRegExp0=^(?!.*24041 Lg ).*
Conjunction=AND
IndexTypes=Standard

You can also define these filters at project level:

[GenerationFilterRule_ProjectFilterRule]
Catalogs=cat/lochplatten_ecat
AlgoTypes=IMG
IndexTypes=Standard
PrjRegExp=^(?!din_24041_lg\.prj$).*
