Instructions

• Step 1 -- Select the Field you want to search.
• Step 2 -- Enter the TEXT you want to find in the Field.
• Step 3 -- Click Search and the results will appear above.
• NOTE: Entering any Search TEXT will produce records that contain exactly AND only that TEXT.
• 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 "berg" will provide people (in the table) with the last name of exactly Berg. Whereas using "%berg" provides people with the last name of Berg and Berenberg. Using '%berg% provides people with the last name of Berg, Beren berg, and Berger.
• 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 "an_" will provide "Ana" and "Ann". Whereas using "an__" (note, two underlines) will provide " Anne", "Anna", and "Aner".
• Also, using combinations of the "Wild Card" and "Placeholder" Characters can be used for more exotic searches. For example, "a_%_a" will find all first names that start and end with an "a" and that are at least four characters long such as "Adana" and "Alexandra", but not "Ana"
• 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.
• Please Note: All of this was accomplished by use of a simple MySQL Query, namely:
  
  "SELECT * FROM contacts WHERE $field LIKE '$text' ORDER BY $field"

    <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.
