Question

假设我有以下表格，

    <div class="our-specialties Container">
            <h3 class="primary-text"> Pizzas </h3>
            <div class="container-grid">
                <?php
                    $args = array(
                    'post_type' => 'specialties',
                    'post_per_page' => 10,
                    'orderby' => 'title',
                    'order' => 'ASC',
                    'category_name'=> 'pizza' 
                    ) ;
                $pizzas  =  new WP_Query($args);
                while($pizzas->have_posts()): $pizzas->the_post(); ?>

                <div class="columns2-4">
                    <a href="<?php the_permalink(); ?>">
                    <?php the_post_thumbnail('specialties');  ?>
                    <h4><?php the_title(); ?><span><?php the_field('price');?></span> </h4>
                        <?php the_content();  ?>
                    </a>
                </div>
            <?php  endwhile; wp_reset_postdata();   ?>
            </div>
            <h3 class="primary-text"> Others </h3>
            <div class="container-grid">
                <?php
                    $args = array(
                    'post_type' => 'specialties',
                    'post_per_page' => 10,
                    'orderby' => 'title',
                    'order' => 'ASC',
                    'category_name'=> 'other' 
                    ) ;
                $pizzas  =  new WP_Query($args);
                while($pizzas->have_posts()): $pizzas->the_post(); ?>

                <div class="columns2-4">
                    <a href="<?php the_permalink(); ?>">
                    <?php the_post_thumbnail('specialties');  ?>
                    <h4><?php the_title(); ?><span><?php the_field('price');?></span> </h4>
                    <?php the_content();  ?>
                    </a>
                </div>
            <?php  endwhile; wp_reset_postdata();   ?>
            </div>
        </div>

code for the style sheet

@media only screen and (min-width:768px){

        .container-grid{
            margin-left: -10px;
            margin-right: -10px;
        }
        .container-grid::after{
            content:'';
            display: block;
            clear: both;

        }
        [class*='columns']{
            padding: 0 10px;
            float: left;
        }
        .columns2-4{
            width: 50%;
        }


    }

现在我想找到每天的字数，并删除少数字。为了找到单词count，我写了以下查询，

date_part             string_word                          id
2017-08-08       India America Advance Apartments           1
2017-08-08       Apartments Planner Headlines               1
2017-08-08       India America Headlines Gucci              1
2017-08-08       Images Same Thing Africa                   2
2017-08-08       Images                                     2
2017-08-07       India America Advance Apartments           2
2017-08-07       Apartments Planner Headlines               3
2017-08-07       India America Headlines Gucci              3
2017-08-07       Images Same Thing Africa                   3
2017-08-07       Images                                     4

这将提供以下内容，

SELECT date_part, word, COUNT(*) as total_word_count
FROM table_name LATERAL VIEW explode(split(string_word, ' ')) lTable as word 
where date_part > '2017-08-05'
GROUP BY date_part, word

现在我想删除数小于2的单词。即每个日期应删除1个计数的单词。以下应该是输出，

date_part       word        total_word_count
2017-08-08      India            2
2017-08-08      America          2
2017-08-08      Advance          1
2017-08-08      Apartments       2
2017-08-08      Planner          1
2017-08-08      Headlines        2
2017-08-08      Gucci            1
2017-08-08      Images           2
2017-08-08      Same             1
2017-08-08      Thing            1
2017-08-08      Africa           1
2017-08-07      India            2
2017-08-07      America          2
2017-08-07      Advance          1
2017-08-07      Apartments       2
2017-08-07      Planner          1
2017-08-07      Headlines        2
2017-08-07      Gucci            1
2017-08-07      Images           2
2017-08-07      Same             1
2017-08-07      Thing            1
2017-08-07      Africa           1

这里删除了包含1个计数的单词。这是我想要获得的输出，这也必须与每一天相关。

有人可以帮我这么做吗？
