Digy commented on LUCENENET-169:
--------------------------------
Although you can overcome all of them somehow;
* controlling the the lifetime of IndexWriter/IndexReader in a naturally
manner,
* reopening the IndexReader only when needed using (for ex) FileSystemWatcher,
* providing a separation between data & bussiness layer,
* providing other apps an interface that may want to write its own user
interface,
* accessing a single search service from different web apps/from load balanced
web servers
* controlling the lifetime of searching/indexing code (without being effected
by the restart of the IIS processes automatically when some memory limit is
exceeded (for ex.) )
* Ability to access some system resources that can be restricted by IIS
etc.
make me think a separete search service is a better idea.But at last, it is a
design decision of you.
(Think, A WebApp+Solr in Java world)

> Key: LUCENENET-169
> URL: https://issues.apache.org/jira/browse/LUCENENET-169
> Project: Lucene.Net
> Issue Type: Improvement
> Environment: ASP.NET
> Reporter: Corey Trager
> Attachments: FSDirectory.patch
>
>
> Microsoft has a configuration file for shared hosting for what they call
> "Medium Trust". There are a couple places in FSDirectory.cs that violate
> the restrictions of Medium Trust, but I coded workarounds, shown below.
> #1)
> // Corey Trager, Oct 2008: Commented call to GetTempPath to workaround
> permission restrictions at shared host.
> // LOCK_DIR isn't used anyway.
> public static readonly System.String LOCK_DIR = null; //
> SupportClass.AppSettings.Get("Lucene.Net.lockDir",
> System.IO.Path.GetTempPath());
> #2)
> /// <summary>Returns an array of strings, one for each Lucene
> index file in the directory. </summary>
> public override System.String[] List()
> {
> /* Changes by Corey Trager, Oct 2008, to workaround permission restrictions
> at shared host */
> System.IO.DirectoryInfo dir = new
> System.IO.DirectoryInfo(directory.FullName);
> System.IO.FileInfo[] files = dir.GetFiles();
> string[] list = new string[files.Length];
> for (int i = 0; i < files.Length; i++)
> {
> list[i] = files[i].Name;
> }
> return list;
> /* end of changes */
> // System.String[] files =
> SupportClass.FileSupport.GetLuceneIndexFiles(directory.FullName,
> IndexFileNameFilter.GetFilter());
> // for (int i = 0; i < files.Length; i++)
> // {
> // System.IO.FileInfo fi = new System.IO.FileInfo(files[i]);
> // files[i] = fi.Name;
> // }
> // return files;
> }
