Search instructions

URL

A URL consists of several parts: protocol://host:port/path?query

The protocol:// prefix is ignored when searching as it's not part of the searchable data.

A leading www. in the host will also be ignored for the same reason.

The host contains one or more parts separated by periods (.). The part before the first period is called the hostname. The part after the last period is the top level domain. Every part added to the left of the top level domain sub-domain. I.e. x.y.z is a sub-domain of y.z which in turn is a sub-domain of the top level domain z

See Match Type below for interpretations of the search string.

Results Display

For the Default search mode, the results are shown in a calendar view unless a filter is also added. For all other cases the results will be displayed in a list.

Search Options

Match Type

There are four different search modes:

Default	In the default mode the exact URL (minus the ignored prefixes mentioned above) is searched for. If one leading or trailing wildcard asterisk (``) is added, see Prefix* and Domain below. Any other asterisks will be considered literal parts of the search string. Hence, adding both a leading and a trailing wildcard asterisk is not possible. Example: URL: https://http.cat/206 & Match Type: Default
Prefix	This will return all URL:s that begin with the given string. It returns the same results as Default with a trailing wildcard asterisk. Examples: URL: https://http.cat/2 & Match Type: Prefix URL: https://http.cat/2* & Match Type: Default
Host	This will ignore any path and query parts of the URL and return all URL:s with the specified `host` part. Example: URL: https://http.cat/ & Match Type: Host
Domain	This is similar to the previous but doesn't require the whole `host`. It returns the same results as Default with a leading wildcard asterisk and a period (i.e. `.`). The leading wildcard matches zero or more `sub-domains` as well as zero or one `hostname`. Examples: URL: cat/* & Match Type: Domain URL: .cat/* & Match Type: Default

Date/Time Range

One may specify a start and/or an end timestamp to further restrict the search - both are inclusive. The timestamps consist of a date and an optional time of day. The layout of these input fields are subject to which browser is used.

Example:

URL: https://http.cat/2 & Match Type: Prefix & From: 2022-02-02 09:00

Filtering

Finally one may add extra filters for Mime Type, Status and URL. For each filter one needs to specify one of the three attributes, one of a set of relations and a string. If more than one filter is added, they will all be applied to the list of results.

Remember to actually add the filter before submitting the search.

Example:

URL: https://http.cat/2/ & Match Type: Prefix & Filtering: HTTP Status Is Not "301"
