# Which desktop search tools avoid indexing delays on large file collections based on user reviews?

Indexing delays can make a search tool feel unusable, especially when you're working with hundreds of thousands of files. X1 Search, Listary, and Alfred each take different approaches to keeping things fast. Here's what G2 reviewers say about indexing performance in the desktop search category:

X1 Search uses real-time indexing that keeps the search index current as files and emails arrive, so there's no waiting for batch jobs to complete before new content becomes searchable. Reviewers note the initial index build on very large mailboxes and network drives can take time, but incremental updates after that are fast and run in the background without noticeable system impact.
Listary skips traditional indexing entirely for basic file searches, pulling results directly from the NTFS file system. This means there's zero indexing delay for file name searches. Reviewers describe results appearing the instant a file is saved. For content-level search, it relies on Windows indexing, so speed there depends on the OS configuration.
Alfred uses macOS Spotlight indexing under the hood but adds its own caching and ranking layer on top. Reviewers describe it as faster than raw Spotlight because of optimizations in how it surfaces frequent files and learned preferences. Since it piggybacks on existing indexing, there's no separate index to build or maintain.
Lookeen maintains its own Outlook-specific index that updates as new emails and attachments arrive. Reviewers in large mailbox environments say the initial indexing of a multi-gigabyte mailbox takes a few hours, but once complete, new items are searchable almost immediately. The focused scope on email and attachments means the index stays smaller and faster than general-purpose tools.
Copernic Desktop Search builds a local index across files, emails, and web history. Reviewers note the initial indexing of large drives can be slow and resource-heavy, but scheduled indexing windows help manage the impact. Once the index is built, search speeds are reasonable for moderate file collections.

For those managing large file volumes, do you schedule indexing during off-hours, or is real-time indexing a requirement for your team?

Scheduled indexing can work for archives, but for operational folders, waiting hours for new content to become searchable defeats the point of desktop search.</p> ##### Comment Metadata - Posted at: 4 days ago - Author title: Marketer ### Comment 3 Is real-time indexing actually necessary for most teams or is it more of a nice-to-have? I've been going back and forth on this. For our workflow, scheduled overnight indexing has been fine because we're rarely searching for something we just saved. Curious whether others have genuinely needed the real-time piece or whether it's mostly about peace of mind. ##### Comment Metadata - Posted at: about 2 months ago - Author title: Marketing Executive ## Related discussions - [How well does Trello scale into a larger team?](https://www.g2.com/discussions/1-how-well-does-trello-scale-into-a-larger-team) - Posted at: over 13 years ago - Comments: 6 - [Can we please add a new section](https://www.g2.com/discussions/2-can-we-please-add-a-new-section) - Posted at: over 13 years ago - Comments: 0 - [Quantifiable benefits from implementing your CRM](https://www.g2.com/discussions/quantifiable-benefits-from-implementing-your-crm) - Posted at: over 13 years ago - Comments: 4
