loading slowly when preview with shift

[F-12]

When searched in devdocs.io, content can be loaded fast due to indexDB used by devdocs.io website. But when searched in alfred, it takes too much time to preview the docs. It seems that alfred cannot take advantage of indexDB to cache devdocs documentation, therefore request content via network when using shift to preview the docs.
Is there any solution to promote the preview performance?

here is a solution for those guys deeply depending on alfred-devdocs workflow:

start a local devdocs server according files at [devdocs|https://github.com/Thibaut/devdocs#quick-start],
then modify the baseUrl defined in [devdocs.php|https://github.com/yannickglt/alfred-devdocs/blob/master/src/scripts/devdocs.php] on your disk.

Now you can use shift to preview the search result fast.
