The iplike search provider is not doing his work properly.
When you hit in the search box you can safely add an illike search like for example:

iplike=10.25.40.*

The search box will show a list of available selection, the first is the iplike search query itself and an entry for every ip node that matches the iplike query
iplike: 10.25.40.*

iplike: 10.25.40.1

iplike: 10.25.40.2

.....

When you select the first you expect that all the nodes belonging to that query where added as Focus Nodes on the graph (and nothing happens).
When you select the single node entry you aspect that only the selected node with specified ip address is added (and all nodes to the query are added)
