Sorting lookup elements on bases of length in descending order

[azizullah2017]

Sorting lookup elements on bases of length in descending order, so the larger value of lookup should be matched first. The generator matches the first value and return.

Unsorted lookup

lookup:

• one
• twenty
• twenty one

if input is "twenty one". it matched with "one" and "twenty"

After storing in descending order

• twenty one
• one
• twenty

now if if input is "twenty one", it matched with "twenty one"

Hi @azizullah2017, this PR is quite old, if you do still want to merge it, could you add or expand a unit test to check that this fixes the behavior you mentioned?
