I contacted NLW on their Facebook page.
Here is my post and their reply.
I am have great difficulty searching for marriage bonds on your website.

How do I search for Marriage Bonds?
Following user feedback, we are currently investigating the possibility of creating a bespoke search form for the marriage bonds collection.
*****Obviously this hasn`t been done as yet******
For the moment, to search for the marriage bonds:
1.Enter your search term in the Catalogue
2.Select 'In the Library' from the drop down to the right of your search term
3.Click Search
4.In the left column under 'Collections' select 'More Options'
*****I got as far as this and could find no column for marriage bonds.****
5.Place a tick in the 'Include' column for 'Marriage Bonds'
***** There isn`t one I could see *****
6.Click on the red 'Continue' button
7.The box will close and the results will include only marriage bonds

Many thanks for your enquiry.
You mention that you got as far as point 4, did you see 'Collections' in the left column, and then click on 'More options' at the bottom of that list? Marriage bonds would then be an option in the pop up box that appears (but only if we have relevant bonds in our collections. It's possible we have no bonds relevant to your search term.
As an example, try searching for 'mary jones' (with the '' around it) and selecting 'In the Library' from the drop down then clicking on search. You will see in the left column under 'Collections' - 'marriage bonds' (if there aren't many marriage bonds, you would have to click on 'more options' to see it). Click on 'marriage bonds' and your results will update.
If there are any marriage bonds, they will always appear after clicking on 'more options' under 'collections'.
I hope this helps. The bespoke search form is currently in development, and we hope to have it available soon.
