Search suggestions for solr collections using ajax

[ak19]

For a solr collection, the search box could provide search completion or suggestions (showing terms already present in the index). The solr server knows about it. The search box can use ajax which could in theory communicate directly with the solr servlet to get the search suggestions.

The only hurdle is that we've made the solr servlet inaccessible for non-localhost machines (see the solr.xml file tomcat context file). We want it to be selectively accessibly for these ajax calls being performed from client machines.
