I'm using the API to search for sitegroups as below:
"/_api/web/SiteGroups?$orderby 'Title'&$select=Id,Title,LoginName" + skiptop + "&$filter=startswith(Title,'" + value + "')"
However, I have the problem that in this case, the startswith filter is case sensitive. So, when a user searches for say "App" he gets Approvers, but when he searches for "app" he gets nothing.
I have tried tolower and other combinations of contains.. substringof..
Is there a way making the filter work?
