# boost::urls::params_base::find_last

Find a matching key

## Synopsis

Declared in `<boost/url/params_base.hpp>`

    iterator
    find_last(
        iterator before,
        core::string_view key,
        ignore_case_param ic = {}) const noexcept;

## Description

This function examines the parameters in the container to find a match for the specified key. The comparison is performed as if all escaped characters were decoded first.

The search starts prior to `before` and proceeds backwards until either the key is found or the beginning of the range is reached, in which case `end()` is returned.

## Example

    url_view u( "?First=John&Last=Doe" );

    assert( u.params().find_last( "last" ) != u.params().find_last( "last", ignore_case ) );

## Complexity

Linear in `this‐>buffer().size()`.

## Return Value

an iterator to the param

## Parameters

Name | Description
before | One past the position to begin the search from. This can be `end()`.
key | The key to match. By default, a case‐sensitive comparison is used.
ic | An optional parameter. If the value `ignore_case` is passed here, the comparison is case‐insensitive.
