when performing search queries that often take a long time to return results. Its frustrating when you have to wait to for the search to perform the exact same query every time one clicks the back button after looking at a item in the results.

Steps to reproduce.

1. goto reports tab
2. in search box use "resource ~ <name of resource>
3. When presented with the list of reports, click on the details button for any report.
4. Look at results from the details page, then hit the back button
5. Notice that foreman performs the search all over again instead of getting from a cache.

This problem occurs with every tab (hosts, reports, facts, ...), but it takes the longest with reports due to the large number or reports.

The use of memcache or internal caching mechanisms should fix this issue.
