This example matches pages where the "foo" parameter begins with "ab":
```go-html-template
{{ range where site.RegularPages "Params.foo" "like" "^ab" }}
{{ range where site.RegularPages "Params.foo" "like" `^ab` }}
<h2><a href="{{ .RelPermalink }}">{{ .LinkTitle }}</a></h2>
{{ end }}
```
When specifying the regular expression, use a raw [string literal] (backticks) instead of an interpreted string literal (double quotes) to simplify the syntax. With an interpreted string literal you must escape backslashes.

Go's regular expression package implements the [RE2 syntax]. Note that the RE2 `\C` escape sequence is not supported.

The RE2 syntax is a subset of that accepted by [PCRE], roughly speaking, and with various [caveats].
