The main feature of Grabber is to search images, and as such, many things can impact the results you see.

Search field

What is written in the main search field will usually be passed as-is to the source, so depending on your source, the search syntax might be different.

You should check on the source which syntax they accept, but in most cases, all you have to do is separate each tag with a space.



Sometimes, a source does not allow you to use a given syntax, or limits the number of terms you can use.

In this case, the best solution is to use a post-filter, which loads the results from the source using your search, then filter them with another search.

⚠️ If your post-filter is too specific, all images might get filtered and Grabber will show zero results! ⚠️


Post-filtering uses the most popular search syntax in boorus, which is:

  • Separate tags by spaces to make a “AND” (ex: tag1 tag2)
  • Prefix a tag or a filter by a caret (-) to negate it (ex: -tag)
  • field:value to filter by a token (ex: rating:safe), the list of tokens can be found on the Filename page
  • field:>value to filter by a token value using a comparison (ex: id:>1000), you can use any of these operators: >, >=, <, <=
  • to filter by a range (ex: date:2019-09-02..2019-09-07)

Special “grabber” token

A special token is generated by Grabber for images to be used by post-filters. It allows to filter on a few special values:

  • grabber:alreadyExists if an image already exists on disk
  • grabber:inMd5List if an image’s MD5 is already present in the global MD5 list
  • grabber:downloaded if either grabber:alreadyExists or grabber:inMd5List is true
  • grabber:favorited if the image’s tags contain a favorited tag



You can blacklist some tags or combinaison of tags to not see them in the results.

It can be edited in the settings in the “Save > Blacklist” category, or tags can be added to the blacklist by right-clicking on them and selecting “Blacklist”.


Each line of the blacklist corresponds to a conbinaison of tags, and use the same syntax as post-filters.


Given this blacklist:

tag2 tag3
tag4 rating:safe

An image will be considered as “blacklisted” if either of those three conditions is met:

  • The image contains the “tag1” tag
  • The image contains both the “tag2” and “tag3” tags
  • The image contains the “tag4” tag and its rating is “safe”
