Accessing an indexed item from a custom security provider

I'm in the middle of writing a custom security provider and am seeing if there was a way to retrieve the indexed item and its indexed fields from a string reference to it in the following format:

I've started to use the Coveo SOAP API to retrieve the item but I've quickly come to realize that this may not be the best way to go. Thoughts?

Alternative thought - would I be able to modify this string reference to add additional fields that I can parse?

There is no clean way to retrieve an indexed item from a security provider. Depending on what exactly you want to achieve, there should be a way to get the information required on the entity you are expanding in the security provider without having to retrieve it from the index.

I actually need to retrieve an indexed field on the entity to determine whether a user is able to access the item or not. Is there a way to access the entity fields from the security provider?

Bumping this up - any help on getting information on the indexed entity?

As Louis-Daniel mentioned, there is no official way to query the index from the security provider - in fact, it is possible for a security provider to be called for a document's permissions before that document is officially in the index (since the document is written in a transaction and unavailable until the transaction is actually applied to the index).

Perhaps sharing a bit more of your use case could help us determine the best way to go forward?

I am trying to trim search results going to the Coveo for Sitecore Search View component. The authorization scheme is a RESTful web service that takes in some data that is a field on a Sitecore item and the current user's username and returns a true/false as the user's permission for the item.

Right now I've got a custom security provider with late binding and implemented the AuthorizeUser method intending for it to call the web service; however I'm not able to get the indexed content to pass into the web service. Is there a better way of approaching this than what I'm doing now?

I've looked into trying to do it further down the chain by using a query pipeline on the Coveo REST API but it looks like I can't call a web service from main.js.

In the context of Coveo for Sitecore, I would use the Rest Endpoint Pipeline:

It would be on page load when the REST response comes back from the server. You can then loop through every results and map the permissions at that time.

Progress! I think I'm 90% there. Is there a smart way to recalculate the groupByResults after adjusting the results?

One big problem though - the JSON only returns a page at a time. If I remove a number of results, the page only has a handful of results instead of 10. Any ideas?

That's why I told you to look at the security providers and late binding in the first place. Doing this filtering/security work anywhere after the index has processed the query and returned results will have this problem of having less results and wrong facet items count.
