"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)

INSTRUCTIONS

Downloading:

go get github.com/google/zoekt/

Indexing:

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

Searching

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

Indexing git repositories:

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

Indexing repo repositories:

go install github.com/google/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 \
   -repo_cache ~/repos \
   -manifest_rev_prefix=refs/heads/ --rev_prefix= \
   master:default_unrestricted.xml

Starting the web interface

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

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/google/zoekt/cmd/zoekt-indexserver

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

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

This will mirror all repos under ‘github.com/username’ 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 Alexander Neubeck for coming up with this idea, and helping me flesh it out.
