How to get form parameters and placeholders is covered in Mojolicious::Guides::Tutorial. I see you've commented out Mojo::SQLite, but I personally like these Mojo-style DB adapters.

Form parameters don't normally get put in the URL in the way you seem to be hoping. One possible solution would be JavaScript, but here is a solution without it: the HTML form gets submitted to a handler at /search, which then just redirects to the corresponding URL. Note I'm generating the form via Mojolicious::Plugin::TagHelpers.

#!/usr/bin/env perl
use Mojolicious::Lite;
use Mojo::SQLite;

helper sqlite =>
    sub { state $sql = Mojo::SQLite->new('sqlite:mydb.db') };

# disable template cache when running under morbo
app->renderer->cache->max_keys(0) if app->mode eq 'development';

app->sqlite->migrations->from_string(<<'END_MIGR')->migrate;
-- 1 up
CREATE TABLE contacts (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    name TEXT,
    department TEXT
);
INSERT INTO contacts (name,department) VALUES ('John Doe','Perl');
-- 1 down
DROP TABLE IF EXISTS contacts;
END_MIGR

get '/' => sub {
    my $c = shift;
    $c->render('main');
} => 'index';

post '/search' => sub {
    my $c = shift;
    $c->redirect_to(
        $c->url_for('name_query', query => $c->param('name') ) );
} => 'search';

get '/name/:query' => sub {
    my $c = shift;
    $c->stash( rows =>
        $c->sqlite->db->select(
            'contacts',
            ['id','name','department'],
            { name => $c->stash('query') }
        )->arrays );
    $c->render('main');
} => 'name_query';

app->start;

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
