What parameters do the "intention" have in dashboard?

Hi Splunkers,

I have a question about the following XML. ＜module name="ConvertToIntention"＞ ＜param name="settingToConvert"＞index_setting＜/param＞ ＜param name="intention"＞ ＜param name="name"＞stringreplace＜/param＞ ＜param name="arg"＞ ＜param name="index"＞ ＜param name="fillOnEmpty"＞True＜/param＞ ＜param name="prefix"＞index=＜/param＞ ＜param name="value"＞$target$＜/param＞ ＜/param＞ ＜/param＞ ＜/param＞

Then I've checked that the ConvertToIntention module has a intention parameter in module references. But I couldn't get name, arg, index parameters. Where do those parameters come from ? Are there any resources ?

Thank you for your help.
