Stop words

All keywords are treated as logical AND. In you want a keyword excluded you could add -keyword.

• secret - returns all files containing secret in filename.
• secret -html - returns all files containing secret and do not contain html in filename.

Full Path

When full path enabled:

Searching for Metallica will return both

When full path disabled:

Searching for Metallica will return:

Filename Extensions

You can filter files by using filename extensions. You can do the following:

• You can find files of one extension ( e.g. file all zip files), or more (file all files that their extension is zip, rar, gz, tar).
• You can combine filename extensions with regular keywords and stopwords.
• You can combine filename extensions with Regular expressions.

Limitations

• You cannot use both, Extensions and Exclude extensions.
• Package limitations here

Basics

This functionality allows you to use input as a regular expression. To see how regular expressions are different from simple search click here

Some notes and implementation details:

• Regular Expressions search is only enabled for Enterprise packages. For more information click here
• Before indexing, all text is converted to lower case, to make search easier.
• Each user can run only one regex at a time.
• Regex has to match the whole filename. That basically means that you will have to add .*{regex}.* most of the time. Also ^ and $ are implicit and removed if entered.
• The domain and protocol should not be matched with the regex. A url will be returned if the regex matches the filename part of the url (bold in the following example) http://somebucket.s3-eu-west-1.amazonaws.com/images/image.jpg
• . ? + * | { } [ ] ( ) " \ are special chatacters. To search for those special characters use a backslash \ for example .*\.jpg searches for files ending with .jpg. That means it will return filename.jpg bug will exclude somefilejpg

Some examples

• .*backup.*
  • Finds everything that contains backup, like thebackup, backup2 _backup_ etc.
• .*2018[\-_\. ]11.*
  
  • Find everything related to November 2018
• .*dump.*(gz|tar|zip)
  • Find all files containing keyword "dump" and end with gz, tar, or zip
• backup.*
  • Find all files that BEGIN with backup
• .*backup
  • Find all files that END with backup.
• .*\.php
  • Find all files with php extension in the site
• 19[0-9]{2}

  • Text that contains 19 and then exactly 2 digits from 0-9
• .*"test.txt"
  • Everything in "" is literal and its not used as in the engine.

Regex Autocorrect

Our system is build in such a way, so that the input regex must match the complete filename, start to end in order to be returned.

Most people expect that if their regex matches partially in a filename this will be returned. Because not all users are advanced, we try to autocorrect the regular expressions, so that most results are returned. We have choose, when we autocorrect the regular expression to leave the change is visible to the user, so that advanced users can see the change and adjust. The rules are:

• When the regex does not start with .* or ^(=start of string) we add .*.
• When the regex does not end with .* or $(=end of string) we add .*.

If you do not want the system to auto-correct the regular expression, you can use ^ and $, or check the "Do not autocorrect regex" option.

Exclude Buckets

Buckets can be excluded from search results by clicking the icon next to the bucket as shown below.

Include Buckets

Buckets can be included in search results (again) by clicking the icon next to the bucket under the Ignored Buckets section as shown below.

Limitations

Unregistered users cannot exclude buckets. Registered users can exclude up to 5. Premium users can exclude up to 15, and Enterprise users have no limitations. See all limitations here.
