Note: We are aware of a bug with Search that only let you type four characters before you have to click back into the search field to complete your term. Search itself is working as expected. We expect this issue to be addressed when we upgrade the platform later this year, and will post an update when one is available. If you have any questions please post in the Community Help forum.
Search:
A static header always appears while the user scrolls up or down the page. This header contains the site name, groups icon, search bar, and personal icons.
Search is context-sensitive in that it recognises the context it's being used in (such as a specific group or application) and returns results based on it. For example, people search assumes your context is the entire community.
Additionally, the results can be filtered by other parameters (application, groups, content or everywhere).
When typing a search in the context of a forum, Arm Community returns possible threads that might answer your question, or might provide the needed information.
Arm Community supports performing wildcard searches using question (?) or asterisk (&) for people and groups.
