As my vault currently contains nearly 1,000 items with Aliases (after moving from Bitwarden), finding specific entries quickly has become challenging. A more powerful, structured search syntax would significantly improve efficiency for all users with large vaults.

I propose implementing advanced search capabilities that allow querying specific fields and filtering by item properties.

• Field-Specific Search Allow users to target a search term to a specific field. The syntax could look like this:

title:live (to find all items with "live" in the title)
username:admin (to find all logins with "admin" as the username)
notes:"secret question" (to find items containing this exact phrase in the secure notes)
url:github.com (to find all items linked to that URL)

• Property-Based Filters Allow filtering based on the state, type, or location of an item. Examples:

has:passkey (or passkey:true / passkey:false)
has:attachment
is:pinned
type:login (or type:note, type:alias)
vault:"Work" (to filter by a specific vault's name)

• Combining Filters Ideally, we could combine these for very precise queries using boolean operators:

title:Microsoft AND has:passkey
type:login AND NOT url:google.com

• Bonus Feature: Smart Vaults / Saved Searches As an additional feature, allowing users to save a complex filter query as a "Smart Vault" or "Saved Search" would be incredibly powerful. For example, one could create a dynamic vault of all items that has:passkey or all items from a specific url:.

Benefit:
Implementing these features would empower users to organize and find their credentials and notes with much greater speed and precision. This would make Proton Pass an even more powerful tool for those of us managing a large number of items.
