i guess that the spatial index should be created as usual, but, as you say, only including selected features if the Processing settings is configured to use only those ones. I dont see any specific thing about it being a Processing algorithm, other than that. An even if you create it for the

Hi, Some existing Processing algorithms could be faster by making use of a spatial index, e.g. http://hub.qgis.org/issues/15012 What's the recommended way to implement a spatial index in a processing algorithm to ensure consistent behavior with other tools (e.g. concerning using only selected
