    <p>Looks like you either need to create a separate filter for each column and combine them with an <a href="http://java.sun.com/javase/6/docs/api/javax/swing/RowFilter.html#andFilter%28java.lang.Iterable%29" rel="noreferrer">AndFilter</a>, or write your own filter by overriding the <a href="http://java.sun.com/javase/6/docs/api/javax/swing/RowFilter.html#include%28javax.swing.RowFilter.Entry%29" rel="noreferrer">include()</a> method. A RegexFilter only requires one of the specified columns to match, and there doesn't seem to be a way to change that.</p> <p>By the way, if you want to force the regex to ignore case, you should add <code>(?i)</code> to the beginning of it. The string you're generating is the same as the one you started with, despite your use of the CASE_INSENSITIVE flag.</p> <p>EDIT: The doc I linked to contains an example of creating an AndFilter from two RegexFilters, but the example is pretty silly. It creates a filter that looks for <code>foo</code> in any column or <code>bar</code> in any column--which is exactly the same as a single RegexFilter with <code>foo|bar</code> as the regex and no columns specified. A good AndFilter example should do something only an AndFilter can do: enforce conditions on two or more columns at once, like you're trying to do. Here's how I would filter case-insensitively for <code>Zac</code> in the first column and <code>A</code> in the second:</p> <pre><code>List&lt;RowFilter&lt;Object,Object&gt;&gt; rfs = new ArrayList&lt;RowFilter&lt;Object,Object&gt;&gt;(2); filters.add(RowFilter.regexFilter("(?i)^Zac$", 0)); filters.add(RowFilter.regexFilter("(?i)^A$", 1)); RowFilter&lt;Object,Object&gt; af = RowFilter.andFilter(rfs); </code></pre> <p>Also, if I were accepting the filter text as user input (which you seem to be doing), I would probably quote it first:</p> <pre><code>String regex = "(?i)^" + Pattern.quote(input) + "$"; </code></pre>

    1. COJust to be clear, you can add an AndFilter to another AndFilter correct? Also, where do I add the `(?i)`? Everywhere I have put it, I get an error.

    2. COAn AndFilter ISA RowFilter, so I don't see why you couldn't add one to another, but I don't see a need to do that here. See my edit, which covers the `(?i)` as well.

    3. COI got the insensitive case to work. I did not include the `^` or `$` though, just the `(?i)` - it didn't work otherwise. Working on making the `AndFilter` now.

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.
