I have been using the Data plug-in on several pages and appreciate its functionality; however, I can't find any documentation regarding the the URLs it generates. Such documentation would be useful in creating (for example) a page which includes a filter-by-letter feature in addition to the filter-by-keyword feature already present. Here is a clearer description of the example scenario:
Suppose there exists a namespace in which each topic is the name of a person in citation order (that is, last name first) and each topic includes a structured data block specifying (among other things) keywords related to the person about whom the topic relates. Also suppose that the default page of the namespace presents a structured data table listing information from 50 of the subordinate topics and presents a data cloud allowing filtering by keyword.
For a small working example, which might be clearer, see

All of that is easily 'do-able' with the existing data plug-in... but it would be nice to be able to permit the user to click on a letter (appearing in a small table, perhaps) to invoke the data plug-in's filter syntax 'filter ~A*', for example, to restrict the display to page titles beginning with the letter 'A'. Obviously, one could achieve this with 26 pages, each a clone of the default page with the filter syntax itself changed; however, I'd guess that the syntax of the 'dataflt" parameter to data plug-in would also support it.
Any thoughts??
