Find-PSResource with multiple tags not working as expected

[jdhitsolutions]

Prerequisites

• [X] Write a descriptive title.
• [X] Make sure you are able to repro it on the latest released version
• [X] Search the existing issues.

Steps to reproduce

I can run these commands to search for resources by tag.

Find-PSResource -Tag yml -type module
Find-PSResource -Tag json-type module

The -Tag parameter will accept an array, so it is reasonable to assume I can run:

Find-PSResource -Tag yml,json -type module

Expected behavior

I would expect to see the results from the two separate commands.

Actual behavior

I get the error: Package with Tags 'yml, json' could not be found in any registered repositories

The parameter will work only when all tags are in the same module.

Indeed, it looks like Find-Module's OR logic with respect to multiple tags mistakenly became AND logic in Find-PSResource.

@jdhitsolutions thanks for creating this issue! We intentionally changed our -Tag logic to reflect AND logic with Find-PSResource instead of OR, so that the search is less computationally expensive and the search result is narrower. If a user wishes to see packages with tag1 OR tag2 they would need to provide 2 separate commands.

Good catch that the docs do not yet reflect this, we will update this on our end, thanks!

@jdhitsolutions in the docs for Find-PSResource for the -Tag parameter it states, "If multiple tags are specified, the cmdlet only returns resources that include all the tags provided." Just wanted to point to that, but please feel free to re-open if you feel we should add more clarity thanks :)
