+Using Sourcegraph to Search 34,000+ Fedora Repositories

+
+In October 2021, a Fedora Linux user [asked a question about licensing][4]. Fedora Project Leader Matthew Miller [left a response][5]: “Since we don’t have a complete, exploded, searchable repository of all of the packages in Fedora, I don’t have a quick way to check.” 
+
+[Followed by][6]: “…or possibly pay Sourcegraph to do it for us. They seem like nice people.” He is correct, we (Sourcegraph) _are_ nice people, but we don’t want your money. Instead, we wanted to team up with the Fedora community.
+
+The Fedora Community can now search their universe of open source code—currently over 34,000 repositories and counting.
+
+### Introduction to code search
+
+For those who aren’t familiar with the concept of [code search][7], it enables teams to onboard to a new codebase and find answers faster, helps to identify security risks, and many other use cases. Sourcegraph has indexed over two-million repositories across multiple code hosts such as GitHub and GitLab. **This article is going to focus strictly on code search for _src.fedoraproject.org_.** Sourcegraph provides both a [web app][8] and [CLI][9] interface.
+
+### Using the Web app
+
+When using the Sourcegraph [web app][8] you will need to start each search with **repo:^src.fedoraprojects.org** before entering any search queries. Using this link to the [web app][8] will include this initial string as shown here:
+
+![Sourcegraph web app interface][10]
+
+The following sections will provide some web app examples of searches that might be of interest.
+
+#### Find repositories using popular OSI-approved licenses 
+
+The following query will scan all the repositories for software that is compatible with the “Open Source Definition” (OSD).
+
+```
+
+    repo:^src.fedoraproject.org/ lang:"RPM Spec" License: ^.*apache|bsd|gpl|lgpl|mit|mpl|cddl|epl.*$
+
+```
+
+![License search][11]
+
+[Try it!][12]
+
+#### Find files with TODOs
+
+The following query can find TODOs in 34k repositories. This is great for those looking to contribute to projects that need help.
+
+```
+
+    repo:^src.fedoraproject.org/ "TODO"
+
+```
+
+![Search for TODO][13]
+
+[Try it!][14]
+
+#### Find files being served via FTP
+
+A co-worker of mine from back in the day told me “FTP is a dead protocol”. Is it? You can add to this query to find any other protocol such as irc, https, etc.
+
+```
+
+    repo:^src.fedoraproject.org/ (?:ftp)://[A-Za-z0-9-]{0,63}(.[A-Za-z0-9-]{0,63})+(:d{1,4})?/*(/*[A-Za-z0-9-._]+/*)*(?.*)?(#.*)?
+
+```
+
+![Search for protocol][15]
+
+[Try it!][16]
+
+#### Find files with a vulnerable version of Log4j
+
+This query will find any files that are possibly vulnerable (false positives can happen) to CVE-2021-44228 aka Log4j. You can also search for other vulnerabilities that can then be reported to project maintainers.
+
+```
+
+    repo:^src.fedoraproject.org/ org.apache.logging.log4j 2.((0|1|2|3|4|5|6|7|8|9|10|11|12|13|14|15)(.[0-9]+)) count:all
+
+```
+
+![Search for log4j][17]
+
+[Try it!][18]
+
+### Use the CLI
+
+Sourcegraph also has a command-line interface tool called [src][19], which allows you to do everything I just mentioned above, plus other useful commands like getting results in JSON for programmatic consumption.
+
+```
+
+    src search -json 'repo:^src.fedoraproject.org/ lang:"RPM Spec" License: ^.*apache|bsd|g
+    pl|lgpl|mit|mpl|cddl|epl.*$'
+
+```
+
+#### JSON output
+
+![JSON output][20]
+
+[Try it!][21]
+
+### Search Syntax
+
+The examples shown may be a good starting point but are by no means the only queries that may be made. You can [view all search query syntaxes][22] and create your own as needed.
+
+### Conclusion
+
+As you can see, with Sourcegraph, the Fedora Linux community can now quickly search for all code hosted at [src.fedoraproject.org][23], regardless of whether they are literal or complex regex queries.
+
+I appreciate the Fedora Linux community being so helpful and welcoming. If you have anything you want to add or questions, my team and I will be in the comments section below. You can also [join us on Slack][24].
+
+Special thanks to [Vanesa Ortiz][25] for [making this collaboration happen][26], [Ben Venker][27] for his help fixing my broken regex (multiple times), as well as [Rebecca Dodd][28] and [Nick Moore][29] for their help with editing.
