How to Search Cloud Storage Buckets Like a Pro: A Practical Guide

Ever stumbled upon publicly exposed cloud storage buckets and wondered how to search them efficiently? Whether you're a security researcher, data analyst, or just someone curious about what's floating around in the cloud, knowing how to filter and find specific files can save you hours of manual work.

Let me walk you through some practical techniques that'll make your bucket searches way more productive.

Understanding Keyword Logic: The AND Rule

Here's the thing about search engines for cloud buckets—they treat every keyword you type as a logical AND by default. That means if you search for "backup database," you're looking for files that contain both words in their filename.

But what if you want to exclude certain results? That's where the minus sign comes in handy. Just add a dash before any keyword you want to filter out.

For example, searching for secret pulls up every file with "secret" in the name. But if you're drowning in HTML files and want to skip those, just search for secret -html instead. This returns all the secret files while filtering out anything with "html" in the filename. Simple, but incredibly effective when you're dealing with thousands of results.

Full Path Search: Digging Deeper Into Folder Structures

This is where things get interesting. The full path toggle changes how your search interprets file locations, and understanding this can dramatically improve your results.

When full path is enabled, your search looks at the entire URL structure. Let's say you're searching for Metallica (hypothetically speaking, of course). You'd get results like:

• files/Metallica - Outlaw Torn.mp3

• files/Metallica/Bleeding me.mp3

Both matches show up because "Metallica" appears somewhere in the complete path.

When full path is disabled, the search only checks the actual filename, not the folder structure. Using the same example, you'd find:

• files/Metallica - Outlaw Torn.mp3

But you'd miss:

• files/Metallica/Bleeding me.mp3

Why? Because in the second case, "Metallica" is the folder name, not part of the filename itself.

This distinction matters more than you'd think. If you're hunting for specific file types scattered across different directories, enabling full path gives you broader coverage. But if you want precision and know exactly what the file should be called, disabling it keeps your results cleaner.

Filtering by File Extensions: Get Exactly What You Need

File extension filtering is one of those features that seems basic until you realize how powerful it is. Here's what you can do:

Single extension searches work great when you know exactly what format you're after. Looking for configuration files? Search for .json or .yaml. Need archives? Go for .zip.

Multiple extension searches let you cast a wider net. You can search for .zip, .rar, .gz, and .tar all at once, which is perfect when you're looking for compressed files but don't know which format was used.

The real power comes when you combine extensions with keywords. Try something like "backup .sql" to find database dumps, or "credentials .txt .json" to locate potential configuration files containing sensitive information.

You can even mix extensions with regular expressions for advanced pattern matching, though that's getting into power-user territory.

Important Limitations to Keep in Mind

Before you go wild with these search techniques, there are a couple of restrictions worth knowing:

You cannot use both inclusion and exclusion for extensions simultaneously. It's either/or. So you can search for files that ARE .zip, .rar, or .gz, or you can search for files that are NOT .html or .txt, but you can't do both in the same query.

Also, different subscription packages have different search limitations. Free accounts typically have caps on search volume and result depth, while premium packages offer more flexibility. It's worth checking what's available at your tier before planning any large-scale searches.

Putting It All Together

The best searches combine multiple techniques. Start broad with keywords, then narrow down with stopwords. Toggle full path based on whether you're looking in filenames or folder structures. Layer on file extensions to zero in on specific formats.

With practice, you'll develop an intuition for which combination works best for different scenarios. Security research? Combine sensitive keywords with common config file extensions. Data recovery? Use full path with archive extensions. Content discovery? Keywords with full path disabled for precision.

The key is experimentation. Cloud storage buckets contain everything from forgotten backups to accidentally exposed databases, and knowing how to search them effectively makes all the difference between finding what you need and getting lost in noise.
