# Email search

The commitment from last spring, the quote as a PDF attachment, the agreement with a customer five years ago: Lookeen finds email by its content – including attachments and old archives.

## How you find any message

Depending on what you still remember, a different path leads to the result.

### By content

Lookeen searches subject, body and attached files. Matches are highlighted in the preview.

### By person

Filter by sender or recipient, or show the whole correspondence with one person in a single click.

### By period

Date filters and queries like “date:\[20240101 to 20240331\]” narrow it down to the right period.

### By attachment

Only messages with attachments, only PDFs, only Excel files – the “Attachments” category collects them.

### With search syntax

Phrases in quotes, OR, exclusion with minus, wildcards, fields like from: or subject: and fuzzy search for typos.

### With favourites

Save recurring searches as favourites and run them again with one click.

### Keep working with your email

Reply, reply all, forward, move to an Outlook folder, send as ZIP or tag – straight from the result list, for one or many messages.

With [Lookeen AI](https://lookeen.com/ki) you summarise long threads, get replies drafted or ask across all your email: “What did we agree with customer Meier?”

## Frequently asked questions

What Lookeen finds in attachments, archives and large mailboxes.

Does Lookeen search attachments inside ZIP files?

Yes. Lookeen opens common archives such as ZIP and searches the files inside by content.

How much email can Lookeen search?

Mailboxes with hundreds of thousands of messages and gigabytes of archives are no problem. Search stays fast because Lookeen uses its own index.

What about scanned attachments?

With OCR switched on, scanned PDFs and images in attachments become searchable too. More under [OCR for scanned documents](https://lookeen.com/use-cases/ocr-scanned-documents).
