lightkurve should cache its SearchResult object

See original GitHub issue

I think lightkurve should somehow cache the SearchResult object, so that if MAST goes down (as it frequently does) or if I’m coding on a plane (as I frequently am) if I run my lk.search_lightcurvefile('NAME') it still gives me the same result, and .download() will just fetch the path to the cached file.

This is quite a difficult feature to add, but I think it should be possible.

Agreed that the lifetime of the cache would definitely have to be set/configured/checked!

We may have a look into it, time-permitting.

I am going to close this issue for now because the caching of search results is being implemented as an astroquery feature, most notably here: https://github.com/astropy/astroquery/pull/1634

Depending on how this feature will be implemented inside astroquery, we may or may not have to open a new issue to add support for it inside Lightkurve.

Footnote: as of Lightkurve v1.9.1 the speed of search operations has been increased ten-fold, so anyone who finds this issue because their search operations are slow may want to upgrade to >1.9.1!
