    <h2>Instructions</h2>

    <ul class="instructions">
        <li>
            Step 1 -- Select the Field you want to search.
        </li>
        <li>
            Step 2 -- Enter the TEXT you want to find in the Field.
        </li>
        <li>
            Step 3 -- Click Search and the results will appear above.
        </li>
        <li>
            NOTE: Entering any Search TEXT will produce records that contain <b>exactly AND only</b> that TEXT.
        </li>
        <li>
            Using a "Wild Card" Character usually provides more results. This can be preformed by using the percent sign
            (i.e., %). For example, searching Last Name Field with the text "<span class="highlight">berg</span>" will
            provide
            people (in the table) with the last name of exactly <span class="highlight">Berg</span>. Whereas using
            "%berg"
            provides people with the last name of <span class="highlight">Berg</span> and Beren<span class="highlight">berg</span>.
            Using '%berg% provides people with the last name of <span class="highlight">Berg</span>, Beren
            <span class="highlight">berg</span>, and <span class="highlight">Berg</span>er.
        </li>
        <li>
            Another option is using the "Placeholder" Character. This can be preformed by using the Underline Character
            (i.e., _).
            For example, searching the First Name Field using a first name of "<span class="highlight">an_</span>" will
            provide "<span class="highlight">Ana</span>" and "<span class="highlight">Ann</span>". Whereas using
            "<span class="highlight">an__</span>" (note, two underlines) will provide "
            <span class="highlight">Anne</span>", "<span class="highlight">Anna</span>", and
            "<span class="highlight">Aner</span>".
        </li>
        <li>
            Also, using combinations of the "Wild Card" and "Placeholder" Characters can be used for more exotic
            searches. For example, "<span class="highlight">a_%_a</span>" will find all first names that start and end
            with an "a" and that are at least four characters long such as "<span class="highlight">Adana</span>" and
            "<span class="highlight">Alexandra</span>", but not "<span class="highlight">Ana</span>"
        </li>
        <li>
            Please enter only characters a-z, A-Z (case does not matter), Numbers 0-9, Percent sign (i.e., %), and
            Underline (i.e., _). Entering other characters may produce odd results.
        </li>
        <li>
            Please Note: All of this was accomplished by use of a simple MySQL Query, namely:<br><br>
            <span class="blue">"SELECT * FROM contacts WHERE $field LIKE '$text' ORDER BY $field"</span>
        </li>
