Setting Up Search
How to Search in ArchiveBox
You can search your ArchiveBox data in a number of ways:
using the CLI:
archivebox list --filter-type=search 'text to search'
(archivebox list --help
for more)using the Web UI: both the
/public
index and/admin/core/snapshot
pages provide a search boxusing the REST API:
/api/v1/list?filter_type=search
provides the same search interface as the CLIby searching the archive data folder directly with external tools (e.g. macOS Spotlight, Cerebro,
ag
, Yacy, etc.)
How Search Works
ArchiveBox search works by doing substring matches in Snapshot
metadata fields (url
, title
, timestamp
, tags
), and by searching the full archived content within each Snapshot (using the selected search backend below). You can find the search implementation source code here: archivebox/core/views.py: PublicIndex.get_queryset()
.
Note: ArchiveBox currently only returns the bare list of snapshots that match when performing a search.
This will be improved in the future to highlight the specific paragraph/line/area that matched within a Snapshot.
For now we recommend using Ctl+F in the browser or one of the external tools listed above to further filter for a term within a Snapshot’s contents.
ArchiveBox Search Backends
ArchiveBox provides a number of “Search Backend Engines” to tune its performance & behavior for different use-cases.
# this setting controls which search backend ArchiveBox uses
archivebox config --set SEARCH_BACKEND_ENGINE=[ripgrep]|sonic|sqlite
# to see information about the backend you are currently using, run:
archivebox version
archivebox config --get SEARCH_BACKEND_ENGINE
By default out-of-the-box, the selected engine is a simple but efficient tool similar to grep -r
called ripgrep
.
Ripgrep is currently the fastest available filesystem search tool that scans over the raw archived files on every search. We chose it as the default so that beginners and 95% of users with small collections can have an experience that “just works”, without needing to install and maintain complex additional dependencies or background workers.
However, there are some fundamental limitations of scanning through every file on disk each time a search is done, so ArchiveBox provides a number of additional search backend options for when users outgrow ripgrep
.
[!TIP] You should consider switching ArchiveBox to use
sonic
or another backend IF:
you have more than 1,000 Snapshots saved in your archive
your archive data is stored on a slower filesystem like a spinning hard drive or remote network mount
you want more advanced search features like stemming, boolean operators, and ability to search PDFs, eBooks, ZIP/tar files, etc.
ripgrep
(the default)
If you do not already have ripgrep
installed, follow the instructions here to get it.
ArchiveBox will use ripgrep
by default if it is found, however you can explicitly configure it to be used like so:
archivebox config --set SEARCH_BACKEND_ENGINE=ripgrep
archivebox config --set RIPGREP_BINARY=rg
# check that archivebox detects the installed version:
archivebox version
# then try it out by searching via the Web UI or CLI:
archivebox list --filter-type=search 'text to search for'
Pros
supports advanced searching with regex patterns
simple, few moving parts, and broadly available for all OSs and CPU architectures
0 idle resource use as there is no background indexer process running
0 additional disk storage needed as it searches the original data instead of maintaining a separate index
reasonably fast on NVMe and SSD drives for small collections
Cons
very slow as archive collection size increases (doesn’t scale well beyond 500~1,000 Snapshots)
very slow if underlying filesytem is slow (e.g. HDDs or network mounts)
doesn’t support stemming, boolean operators, or other advanced full-text search features
ripgrep-all
(aka rga
)
The same as ripgrep except that it supports searching more binary filetypes like PDFs, eBooks, Office documents, zip, tar.gz, etc.
To use it, follow the install instruction for your OS, then configure ArchiveBox to use it like so:
archivebox config --set SEARCH_BACKEND_ENGINE=ripgrep
archivebox config --set RIPGREP_BINARY=rga
# check that archivebox detects the installed version:
archivebox version
# then try it out by searching via the Web UI or CLI:
archivebox list --filter-type=search 'text to search for'
ugrep
Not tested by the ArchiveBox team but it’s very similar to ripgrep
and may work as a drop-in replacement, with some caveats. (contributions welcome to improve support)
ugrep
is similar to ripgrep
and ripgrep-all
in that it’s an indexless disk-search tool, but it provides some more of the full-text search features without the performance overhead of maintaining a separate search backend worker with an independent index.
https://github.com/Genivia/ugrep
archivebox config --set RIPGREP_BINARY=ugrep+
Pros
supports boolean operators in search queries
supports binary formats like compressed archives, PDFs, eBooks, etc.
better support for Unicode, special characters, and searching across multiple lines of text
supports fuzzy search
Cons
not as fast as
sonic
and but also not as simple asripgrep
not all of its features are fully integrated with ArchiveBox yet
sonic
⭐️ (the recommended upgrade path for most people)
Sonic is a fast, lightweight, rust-based alternative to super-heavy traditional search backends like Elasticsearch. It is capable of normalizing natural language search queries, fuzzy matching, and searching Unicode, without needing to maintain a duplicate document store index of all the searchable text.
Internally it functions as an index store, storing only the original IDs of the Snapshots with a super-compressed representation of the text. This allows it to scale to searching terabytes of archive data while maintaining an index only a fraction of that size.
ArchiveBox has supported Sonic for years, and it is the most thoroughly tested and recommended backend for ArchiveBox users that need to scale beyond ripgrep
.
Using sonic with ArchiveBox in Docker Compose is the easiest way to get started, though you can also use it without Docker by installing it manually and then running pip install archivebox[sonic]
.
# edit docker-compose.yml to uncomment the lines that enable sonic
nano docker-compose.yml
# make sure ArchiveBox is configured to use the Sonic backend
docker compose run archivebox config --set SEARCH_BACKEND_ENGINE=sonic
# restart the containers to apply changes and start the Sonic worker
docker compose down
docker compose up
# check that the sonic container started without issues
docker compose logs sonic
docker compose run archivebox version
# backfill any existing archivebox data into the Sonic index (may take an hour or longer depending on storage speed and collection size)
docker compose run archivebox update --index-only
# then test it out:
docker compose run archivebox list --filter-type=search 'some text to search'
Fore more detailed instructions see here…
Pros
extremely fast, most queries complete in microseconds even with 100k+ snapshots
maintains lightweight, compressed search index that is minuscule compared to original data
all-in-one binary written in rust, available cross-platform and easy to deploy
supports advanced full-text search features like normalization, stemming, etc.
supports indexing and querying on a remote server (many ArchiveBox instances can share a single
sonic
instance)
Cons
one extra dependency to install and background worker to keep running (Docker Compose makes this easy though)
does not support searching binary files like PDFs, eBooks, compressed archives, etc.
SQLite FTS5
This is a recently added experimental option that uses a separate SQLite3 Database (similar to the one ArchiveBox already uses for Snapshot metadata) to provide full-text search.
archivebox config --set SEARCH_BACKEND_ENGINE=sqlite
# add existing data to index by running update:
archivebox update --index-only
# test it out using the archivebox Web UI or CLI:
archivebox list --filter-type=search 'some text to search'
# or using SQLite3 directly;
sqlite3 ./search.sqlite3
> SELECT snapshot_id FROM snapshot_fts
INNER JOIN snapshot_id_fts ON snapshot_id_fts.rowid = snapshot_fts.rowid
WHERE snapshot_fts MATCH "some text to search";
# optional advanced tuning:
archivebox config --set FTS_SEPARATE_DATABASE=True
archivebox config --set FTS_TOKENIZERS="porter unicode61 remove_diacritics 2"
archivebox config --set FTS_SQLITE_MAX_LENGTH=1000000000
Pros
No additional dependencies needed to install, SQLite3 is already available and used by ArchiveBox
No long-running background search worker process needed, 0 idle resource use
Supports advanced full-text search features like boolean operators, stemming, phrases, etc.
Comparable speed and efficiency to
sonic
for most use-cases (much faster thanripgrep
/ugrep
)Durability and portability, SQLite is widely used and supported by every major platform on earth
Cons
Not as thoroughly-tested by ArchiveBox team as our
sonic
orripgrep
backendsMaintains a (compressed, but still potentially large) duplicate copy of all searchable text in
search.sqlite3
dbDoes not support searching binary files PDFs, eBooks, compressed archives, etc.
Search indexing and querying must be performed on same server as ArchiveBox data (we don’t yet support sending FTS5 queries to a remote server)
