"Zoekt, en gij zult spinazie eten" - Jan Eertink

("seek, and ye shall eat spinach" - My primary school teacher)

This is a fast text search engine, intended for use with source code. (Pronunciation: roughly as you would pronounce "zooked" in English)

Note: This is a Sourcegraph fork of github.com/google/zoekt. It is now the main maintained source of Zoekt.

INSTRUCTIONS#

Downloading#

go get github.com/sourcegraph/zoekt/

Indexing#

Directory#

go install github.com/sourcegraph/zoekt/cmd/zoekt-index
$GOPATH/bin/zoekt-index .

Git repository#

go install github.com/sourcegraph/zoekt/cmd/zoekt-git-index
$GOPATH/bin/zoekt-git-index -branches master,stable-1.4 -prefix origin/ .

Repo repositories#

go install github.com/sourcegraph/zoekt/cmd/zoekt-{repo-index,mirror-gitiles}
zoekt-mirror-gitiles -dest ~/repos/ https://gfiber.googlesource.com
zoekt-repo-index \
    -name gfiber \
    -base_url https://gfiber.googlesource.com/ \
    -manifest_repo ~/repos/gfiber.googlesource.com/manifests.git \

Searching#

Web interface#

go install github.com/sourcegraph/zoekt/cmd/zoekt-webserver
$GOPATH/bin/zoekt-webserver -listen :6070

JSON API#

You can retrieve search results as JSON by sending a GET request to zoekt-webserver.

curl --get \
    --url "http://localhost:6070/search" \
    --data-urlencode "q=ngram f:READ" \
    --data-urlencode "num=50" \
    --data-urlencode "format=json"

The response data is a JSON object. You can refer to web.ApiSearchResult to learn about the structure of the object.

CLI#

go install github.com/sourcegraph/zoekt/cmd/zoekt
$GOPATH/bin/zoekt 'ngram f:READ'

Installation#

A more organized installation on a Linux server should use a systemd unit file, eg.

[Unit]
Description=zoekt webserver

[Service]
ExecStart=/zoekt/bin/zoekt-webserver -index /zoekt/index -listen :443  --ssl_cert /zoekt/etc/cert.pem   --ssl_key /zoekt/etc/key.pem
Restart=always

[Install]
WantedBy=default.target

SEARCH SERVICE#

Zoekt comes with a small service management program:

go install github.com/sourcegraph/zoekt/cmd/zoekt-indexserver

cat << EOF > config.json
[{"GithubUser": "username"},
 {"GithubOrg": "org"},
 {"GitilesURL": "https://gerrit.googlesource.com", "Name": "zoekt" }
]
EOF

$GOPATH/bin/zoekt-indexserver -mirror_config config.json

This will mirror all repos under 'github.com/username', 'github.com/org', as well as the 'zoekt' repository. It will index the repositories.

It takes care of fetching and indexing new data and cleaning up logfiles.

The webserver can be started from a standard service management framework, such as systemd.

SYMBOL SEARCH#

It is recommended to install Universal ctags to improve ranking. See here for more information.

ACKNOWLEDGEMENTS#

Thanks to Han-Wen Nienhuys for creating Zoekt. Thanks to Alexander Neubeck for coming up with this idea, and helping Han-Wen Nienhuys flesh it out.

FORK DETAILS#

Originally this fork contained some changes that do not make sense to upstream and or have not yet been upstreamed. However, this is now the defacto source for Zoekt. This section will remain for historical reasons and contains outdated information. It can be removed once the dust settles on moving from google/zoekt to sourcegraph/zoekt. Differences:

zoekt-sourcegraph-indexserver is a Sourcegraph specific command which indexes all enabled repositories on Sourcegraph, as well as keeping the indexes up to date.
We have exposed the API via keegancsmith/rpc (a fork of net/rpc which supports cancellation).
Query primitive BranchesRepos to efficiently specify a set of repositories to search.
Allow empty shard directories on startup. Needed when starting a fresh instance which hasn't indexed anything yet.
We can return symbol/ctag data in results. Additionally we can run symbol regex queries.
We search shards in order of repo name and ignore shard ranking.
Other minor changes.

Assuming you have the gerrit upstream configured, a useful way to see what we changed is:

$ git diff gerrit/master -- ':(exclude)vendor/' ':(exclude)Gopkg*'
