In order to communicate with FAST Search via its API, we need to know the port on which the QRServer is running.
I followed these steps to locate it:
- Log into the FAST admin site (http://server:port/admin).
- Navigate to System Overview.
- Locate "Search Dispatcher" and click the spyglass icon:
- I successfully used the value, 15100 for "Info Name" = "http":
1. Port 15100 appears to be the default out-of-the-box port number for the QRServer.
2. Use this code similar to the following to instantiate a connection to FAST:
ISearchFactory searchFactory; NameValueCollection nameValueCollection = new NameValueCollection(); nameValueCollection.Add("fastsearchengine", "Com.FastSearch.Esp.Search.Http.HttpSearchFactory"); nameValueCollection.Add("Com.FastSearch.Esp.Search.Http.QRServers", "fastdemoback:15102"); nameValueCollection.Add("Com.FastSearch.Esp.Search.Http.RequestMethod", "GET"); searchFactory = SearchFactory.NewInstance(nameValueCollection);
3. If you pick a wildly incorrect port, you get a helpful error message:
4. However, if you pick the port number listed on the overview (15102) you don’t get that helpful error message. Instead, later when you try to access any data via a search or reference a FAST view, you get an error. Debugging shows that the searchFactory’s view count is zero. You’ll be given the message "Failed to fetch Search View List".
