I see that the meta in linked to the products in the `_postmeta’ table.
However, the way it is stored does not seem like valid JSON.
I can deduce that a:2 stands for 2 linked meta groups.
i = index (order of meta groups?)
s = unclear
then the last number is the meta group ID
So the example has 2 meta groups
First ID: 10
Second ID: 171
How can I parse the string?
Furthermore, we can investigate MYSQL functions to search JSON if the format is JSON.
