Script Search with Measurements using ” and ‘ in field

I am frustrated attempting to search on a Product Description Field that uses inches and feet throughout each item.

For example:
R-19 16"x96"
R-19 72"x50' Microlite L (6'x50')

The search fails.

I have attempted to add " " around the search item, yet it also fails.
"R-19 16"x96""
to find: R-19 16"x96"
"R-19 72"x50' Microlite L (6'x50')"
to find: R-19 72"x50' Microlite L (6'x50')

Products that don't include " or ' work properly.

This is part of a script to find a corresponding product number and find the inventory quantity.
This would be a very important part of my solution if I could make this work.

PLEASE HELP offer any insights, oversights and suggestions.
