Recursive searching in WebDrawer and ServiceAPI

The CM search syntax allows for recursive searching, for example returning results from folders contained within folders.  The operator that specifies recursion is the plus sign (+), the problem is that in a URL the plus sign is reserved to indicate white space.

To overcome this the ServiceAPI (and WebDrawer) use the tilde (~) instead of the plus sign, so instead of this:

container:[title:asia]+

Do this:

container:[title:asia]~

If you would rather use a character (or sequence of characters) other than the tilde you can customise this in the hptrim.config.  The Web Client, for example, uses _$_ instead of tilde, which is set in the  'searching' element in its hprmServiceAPI.config.

<searching pageSize="30" searchRecursiveOption="_$_"/>
