The Basics: To perform a search, type a collection of search terms into the search bar. The most basic type of search term is a tag on its own. You can see all currently available tags on the Tag Database. If you're not sure whether a tag exists, try typing the first few letters: the system will display suggested tags under the search bar. You don't have to use the full name of each tag - many of them have synonyms, which the system will automatically detect and accept.
Multiple Terms: To search for multiple terms together, place a space in between each separate term.
Modifiers: As well as simply searching for a tag, you can also apply modifiers to the front of a tag in order to change how the search is performed.
Removing a Term: To specify that a search not return any files with a specific tag, place a minus sign in front of the tag. For example, the search -gore will return all images which are not tagged with the "gore" tag.
Character Tags: The following search modifiers only apply when used in conjunction with one of four special character tags. These four tags are "male", "female", "futa", and "char" - they specify the number of males, females, futanari/shemales, and characters in a file, respectively.
Numeric Modifier: To specify that a file have exactly a certain number of one of the character tags, simply put a number in front of the tag. For example, the search 3female will only return files which have exactly three females in them.
Less-Than Modifier: To specify that a file have less than (or equal to) a certain number of one of the character tags, simply put a number in front of the tag, followed by a minus sign. For example, the search 3-male will only return files which have three, two, one, or zero males in them. Note that this is an "inclusive" less than, and that it includes zero.
Greater-Than Modifier: To specify that a file have more than (or equal to) a certain number of one of the character tags, simply put a number in front of the tag, followed by a plus sign. For example, the search 2+female will only return files which have two, three, four, or more females in them. Note that this is an "inclusive" greater than, and that the maximum number of any one type of character is 255.
