Good Afternoon,
After update I have long load of Ajax search pro.
response from the server is about 20-25 sec.
Can you find the problem and give advice how to fix it?
If you have a larger number of products with lenghty contents, I would recommend using the Index Table engine. The tutorial in the link will explain everything about the configuration.
It should greatly increase the performance, if the issue was related to the number of items.
Make sure that the “_sku” custom field is selected under the index table configuration. After that, just re-create the index, and it should be all right.
Your main search bar (ID=1) does not have the “product_variation” post type selected: https://i.imgur.com/8lsqObM.png
If you change that, it should work.
I tried on the product filter search bar (ID=2), it worked fine, I tried the phrase “1720”: https://i.imgur.com/Gb7HD2q.png
