# Regular Expression Search

Browsee's Regular Expression search is somewhat different to other tools you may have used like Google Analytics.

The regular expressions are somewhat similar to the implementation in Javascript.

Here are some examples of regular expressions you may want to use

1. To match all urls with text `abc`

you may use this regular expression: `.*abc.*`

2\. To match all urls with query parameter `source`

you may use this regular expression: .\*/`.*?source.*`

Notice you do not need to escape the forward slash (/).

3\. To match URLs with two level paths like

`x.com/y/z/`

you may this regular expression: `.*/[^/]+/[^/]+/`
