Hi, Gaby — you're probably looking for the window parameter of the NEAR positional operator. I realise as I write this that it isn't terribly well-documented in the API, but there are hints here:

https://xapian.org/docs/apidoc/html/classXapian_1_1Query.html#adb287c496f72327d1c1411fac0570ea9

I've added some notes to our missing documentation list [1] that we need to work on this!
