 <h3>Creating a URL for a Track Hub</h3>
 <p>Hubs can be loaded into the URL using the <code>hubUrl=</code> parameter. This parameter
 takes input similar to the <a href="/cgi-bin/hgHubConnect#unlistedHubs">track hub input box</a>.
 Native UCSC supported genomes can be loaded into the URL using the <code>db=</code> parameter while
 non-natively supported genomes such as assembly hubs or GenArk hubs use the <code>genome=</code>
 parameter. URL parameters can be combined by using <code>&amp;</code>.
 </p>
 <p>The following example links to the hg19 genome database and an example track hub using the <code>db=</code> and the <code>hubUrl=</code> parameters:</p>
 <pre><a href=../../cgi-bin/hgTracks?db=hg19&hubUrl=https://genome.ucsc.edu/goldenPath/help/examples/hubDirectory/hub.txt>http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg19&hubUrl=https://genome.ucsc.edu/goldenPath/help/examples/hubDirectory/hub.txt</a></pre>
 
 <p>Track hubs' track visibility can also be changed from the URL parameters. As an example, the
 following link specifies:

 Browser software attempts to speed performance by reading the trackDb architecture into
 a separate cache. This software assumes that the timestamp on a file like a hub's trackDb.txt should
 always be increasing in time and never decreasing (i.e., a new update to the file should not have
 an earlier timestamp). We did discover that if someone were to copy an older file (say with
 <code>cp -p</code> to preserve file timestamp), for example to restore a trackDb.txt to an earlier
 version, they might get stuck with a hub that is not updating. To resolve this specific problem the
 person would only need to edit or touch the file and give it a new timestamp.</p>

 <h3>Troubleshooting Track Hub connections</h3>
 <p>
 If the browser is unable to load a track hub, it will display an error message. Some common causes
 for an import to fail include typos in the URL, a hub server that is offline, 
 or errors in the track hub configuration files. Occasionally, remote track
 hubs may be missing, off-line, or otherwise unavailable. If a user is
 already browsing data from the remote hub when it disconnects, a yellow error message will be
 displayed instead of the expected data.</p>

 <!-- ========== Setting Up Track Item Search ============================== -->
 <a name="Search"></a>
 <h2>Setting up track item search</h2>
 <p> 
 The Genome Browser supports searching for items within bigBed tracks in track data hubs. To support 
 this behavior you have to add an index to the bigBed file when you initially create the the bigBed 
 file from the bed file input. Indices are usually created on the name field of the bed, but can be 
 created on any field of the bed. Free-text searches can also be enabled by creating a 
 <a href="trix.html">TRIX index file</a> that maps id's in the track to free-text metadata. Further
 instructions can be found in the <a href="hubQuickStartSearch.html">Searchable Hub Quick Start 
 Guide</a>.</p>
 <p>
 See the searchIndex and searchTrix fields in the <a href="trackDb/trackDbHub.html">Hub Track 
 Database Definition document</a> for 
 information on how to set up your bigBed to enable searching. The searchIndex setting requires
 the input BED data to be case-senstive sorted (<code>sort -k1,1 -k2,2n</code>). You can use
 either the example UNIX <code>sort</code> command or the <code>bedSort</code> utility available

 <!-- ========== Adding Filters to Track Hub ============================== -->
 <a name="Filters"></a>
 <h2>Adding Filters to your Track Hub</h2>
 <p>
 The Genome Browser supports three varieties of data filter options for bigBed data.
 These can improve data usability in many ways, such as displaying specific data by default 
 (e.g. only items that pass certain quality scores), allow for filtering based on 
 pre-specified categories (e.g designate only LINE repetitive elements from a list of options) 
 and more.</p>
 <p>
 For more information on the options available and examples on how to set up filters, see our
 <a href="hubQuickStartFilter.html" target="_blank">Track Hub Filters Quick Start Guide</a>
 and the filter entries in the <a href="trackDb/trackDbHub.html#filter" target="_blank">
