    <p>I'm trying to develop a dynamic query builder for days. But I'm having a problem with building it.</p> <p>What I'm reviving is a json like this.</p> <pre><code>{"category":"Case Law","query":{"AND":{"Year":{"having":"","exact":"","any":"","none":""},"AND":{"Report":{"having":"","exact":"","any":"","none":""},"Citation":{"having":"","exact":"","any":"","none":""}}}}} </code></pre> <p>Here is it in much readable way</p> <pre><code>Array ( [category] =&gt; Case Law [query] =&gt; Array ( [OR] =&gt; Array ( [Year] =&gt; Array ( [having] =&gt; some [exact] =&gt; values [any] =&gt; might [none] =&gt; have ) [AND] =&gt; Array ( [Report] =&gt; Array ( [having] =&gt; [exact] =&gt; [any] =&gt; [none] =&gt; ) [Citation] =&gt; Array ( [having] =&gt; [exact] =&gt; [any] =&gt; [none] =&gt; ) ) ) ) ) </code></pre> <ul> <li>this json can change according to the user inputs(can have more depth or less).</li> <li>what I'm trying to do is create a search query for apache lucene...(for the moment lets assume that leaf values are just strings.)</li> </ul> <p>It <strong>must be</strong> something like this(What I need)</p> <blockquote> <p>(Year:another values OR (Report:some valeus AND Citation:some valeues))</p> </blockquote> <p>I tried with Jettison library and used DefaultMutableTreeNode to create the tree structure . But it didn't work as I expected.Then i tried whit recursive functions and it also didn't worked </p> <p>I want to is it possible to create this kind of thing. If yes how to do.</p> <p>Your attempt is highly appreciated! Thanks in advance.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
