how to create a custom field in nuch search engine? - nutch

i want to create a custom field in nutch search engine?
what are the steps i will follow?

I would think your best option is to develop a Nutch Plugin which handles the logic for adding that field on a per crawled page basis.
Please see the Writing Plugin Example wiki article on the Nutch site.

Is it possible to create a wizard in Orchard?

Is it possible to create a wizard in Orchard CMS, perhaps by creating a "Wizard" content type which may have optional content parts depending on rules which may assess previous data entered. This may be asking too much. I am just looking into Orchard as a CMS and I can see how it can be some much more ie an application framework.
Many thanks,
Ed
Orchard is just an Mvc application so you may use any tecnique that works on it.
Look at this blog to see a step by step tutorial:

Are there libraries available that create an image search tool with Apache Solr?

I'm considering using apache solr as the search backbone on my site.
Along with standard text based search of documents, I want to create an image search tool.
Are there any libraries that allow solr to create a search index of images in crawled websites?
Are there other, better, options available?
As #Mikos mentioned in the comments, what I was looking for is a Content Based Image Retrieval system. There does exist on for use with Apache SOLR and it's called LIRe.
Here is a list of CBIR systems on Wikipedia.
Here is the tool that I've been investigating for use with a Linux based image search system I'm working on -- The GNU Image Finding Tool - GIFT. This is open source and seems to be the right tool for the job when you already have the database of images.

Creating Dynamic Sitemap in SharePoint

I have developed a publishing portal in sharepoint.I have a requirement wherein I need to create sitemap for the entire web application.
This should be dynamic, in the sense, whenever we update the contents of any given page in our web application, it should be reflected immediately in the sitemap page. What are the possible ways to achieve this and which is the best possible solution considering the scalability and easy configuration?
Thank you.
If you don't want to use a custom webpart, you could use normal navigation list to create your sitemap and it is automatically updated. You only need to style it in a way to resemble some kind of sitemap.
Here are some links to get you started with customizing your navigation:
Custom Navigation in SharePoint - The Full Monty
How to: Customize Navigation
Also there is the portal site map which provides the data source for your custom menu. Just read up on custom navigation and stuff like PublishingNavigation:PortalSiteMapDataSource and SharePoint:AspMenu.
There is a nice PowerShell script to create a sitemap for SHarepoint 2010, if you want to submit your sitemap to Google: Generate A Sitemap For SharePoint 2010 Using PowerShell'.
You can also install and customize the SharePoint Web part ("Table of Contents") to your liking. Read up on it here...
Take a look at our ECS product, it is close to what you need

It was built as a system of cross site collection navigation, with security trimming and permissions inheritance between site collection.

Please help me
Thanks in advance
You can code this up using some SQL queries and PHP codes to retrieve the contents of your Joomla posts...
or you can use Google's custom search http://www.google.com/cse/
You could integrate Google Search. http://www.google.com/sitesearch/
There are a number of Joomla Site Search Extensions: http://extensions.joomla.org/extensions/search-a-indexing/site-search you could integrate.

Google Custom Search not indexing Dynamic Pages

I am trying to use Google Custom Search to provide search capabilities to an informational site.
About the site:
Content is generated dynamically
URL Access to content is search engine friendly (i.e. site.com/Info/3/4/45)
Sitemap (based on RSS feed) submitted
and accepted by web master tools. It
notes that no pages were indexed.
Annotations sucessfully submitted based on the RSS feed
Problem:
There are no results for any keywords that appear on the pages that were submitted.
Questions:
Why is Google not indexing the submitted pages?
What could I be doing wrong?
Custom Search with basic settings is principally same thing as standard search with site:your.website. Does standard search give you expected results?
Note, that Google doesn't index pages immediately. It takes some time. Check if your site is already indexed.
Yeah it took about 2 weeks for Google to pick up all my pages after I submitted a site map. But you should see a few pages indexed after a couple days.
