Setting Filter on an Analysed Field

Hi,

I am trying to set a filter on the following field;
e.Properties.Uri: https://api.checkout.com/payments/pay_rtpotpropoepoe

It is an analysed Field, so it gets tokenized into two tokens: https://api.checkout.com/payments/ and pay_rtpotpropoepoe
I can filter out based on the 1st token , i.e.: e.Properties.Uri: "https://api.checkout.com/payments/"

How could I add another filter for the 2nd token, please?
When I try with e.Properties.Uri: "pay_rtpotpropoepoe" nothing is returned

Thanks
