whoosh-compat's fieldname tagger is O(n^2) in plain word characters, reachable only through SearchMode.QUERY's whoosh grammar. Measured against the real field registry: ~1s at 10k chars, ~3.7s at 20k, ~14.4s at 40k. The POST selection-filter path (bulk edit, bulk download) has no server-imposed length bound the way the GET path incidentally does via header limits, making an unbounded query a single-request CPU exhaustion vector. Cap both entry points at their shared choke point, _get_tantivy_query_and_mode, with a new QueryTooLongError that reuses the existing SearchQueryError -> 400 routing both callers already have. 4096 chars bounds the worst case to roughly 0.16s by quadratic extrapolation, far beyond any plausible hand-typed query. TEXT and TITLE modes route through simple_search_tokens instead and measure linear even at 20k chars, so the same cap is hygiene for them rather than a fix. Hardcoded rather than a PAPERLESS_* setting: this is a security boundary, and a raisable ceiling could reintroduce the exact hazard it exists to close.

Paperless-ngx
Paperless-ngx is a document management system that transforms your physical documents into a searchable online archive so you can keep, well, less paper.
Paperless-ngx is the official successor to the original Paperless & Paperless-ng projects and is designed to distribute the responsibility of advancing and supporting the project among a team of people. Consider joining us!
Thanks to the generous folks at DigitalOcean, a demo is available at demo.paperless-ngx.com using login demo / demo. Note: demo content is reset frequently and confidential information should not be uploaded.

Features
A full list of features and screenshots are available in the documentation.
Getting started
The easiest way to deploy paperless is docker compose. The files in the /docker/compose directory are configured to pull the image from the GitHub container registry.
If you'd like to jump right in, you can configure a docker compose environment with our install script:
bash -c "$(curl -L https://raw.githubusercontent.com/paperless-ngx/paperless-ngx/main/install-paperless-ngx.sh)"
More details and step-by-step guides for alternative installation methods can be found in the documentation.
Migrating from Paperless-ng is easy, just drop in the new docker image! See the documentation on migrating for more details.

Important Note
Document scanners are typically used to scan sensitive documents like your social insurance number, tax records, invoices, etc. Paperless-ngx should never be run on an untrusted host because information is stored in clear text without encryption. No guarantees are made regarding security (but we do try!) and you use the app at your own risk. The safest way to run Paperless-ngx is on a local server in your own home with backups in place.
