Well-Known Resource Index

Terms

nytimes.com aol.com

Search by domain, resource type, IP, simhash, etc., as well as assorted resource-specific fields. When there are multiple terms only one needs to match.

Phrases

Require and Exclude

nytimes.com aol.com +ads_txt

Add + before a term or phrase to require it, or - to exclude it.

Prefix

nyt*

Add * after a term or phrase to search by prefix.

Filters

resource:ads_txt nytimes.com

Filters restrict results based on specific fields. They are written in the form [filter]:[value].

Most filters accept terms or phrases as values (including support for prefixes). Providing only * as a value will match resources where the relevant field exists, regardless of its value.

Some filters can only check if a field exists, so only work with * value. Others filter on boolean fields, so only work with true or false.

Exclude and Optional

Filters act as required terms by default, but can be excluded instead by adding - before the filter.

nytimes.com ~domain:aol.com

Filters can also made optional adding ~ before the filter.
