All of the content posted within the discussion forums is searchable within the main site search, and, if you are logged in, you can also search and look through the profiles of all of the community members.
Here's how you do it...
Searching the community
You can use the main website search feature to look for specific content on the community, much as you would with a search engine like Google.
Simply type your term in the search box in the top left hand corner (it says 'Site search') then click the magnifying glass icon to run your search.
On the 'Global search' results page, click the 'Community' tab to show only content that appears within the discussion forums.
Searching for users
Type the name of the person you are looking for into the search box, as per the instructions above, and then when you get to the results page, select ‘Community users’ to see a listen of results.
Please note that only users who are logged in are able to search for other community users.
