I am building a phone catalog of my organization (an AJAX application which accesses the search.asmx web service).
I'd like to show a list box where the user could select a department (which is stored in managed property Department). To fill the list box with values, I need to somehow select all the distinct values of that property.
Is it possible through search.asmx web service?
What I've found:
- an article, which states that it is possible, but it does not use the web service interface
- a Microsoft's white paper which states that "If the protocol client specifies at least one property, it MUST also specify the Path property. If it does not, the protocol server MUST return the status code "ERROR_BAD_QUERY"."
The two findings are somewhat inconsistent. (and, yes the search really returns ERROR_BAD_QUERY).
