Dear Readers today i found very interesting item now you can create your own search engine like google in just few steps by using dotnetnuke technology
thanks for zoom
|Zoom Search Engine is a software package that allows you to |
create a powerful custom search engine for your website. It is
unlike other search solutions in that it gives you full control
over its indexing capabilities, and there is no advertising or
annual fees, while being one of the easiest to use and most
feature packed solutions on the market. More on the advantages
of using Zoom here.
The following tutorial explains how to use Zoom with your
DotNetNuke website. Since many DotNetNuke (DNN) users find the
built-in search functionalities of DNN Search to be lacking,
they have found that Zoom is far more capable in providing a
much more effective (both in relevance and performance) search
function to their DNN website. We provide this tutorial to
explain some common details and steps to get a working Zoom
Search Engine up and running, and integrated with your DNN site
as quickly as possible.
What you will need
For larger sites, commercial editions are available. For most
people, the Professional Edition is suitable, which indexes up
to 200,000 pages and costs only US$99. Detailed comparison of
the different editions available can be found
Using Zoom and indexing your websiteUsing Zoom on a DotNetNuke website is much the same as using
it on any other website, so you will find much more detailed
information on installing and running Zoom in the
Guide (free PDF download). We recommend referring to the
Users Guide for most instructions and taking note of the
following tips for guidance/reference for DNN specific details.
But to summarize, Zoom has two main parts. The Indexer
software which runs on your desktop computer, scans your website
and generates a set of "index files". These files are then
uploaded to your website and provide the searching
functionality. You will also be using the Indexer to update your
search engine when you make changes to your website in the
access your new search engine by entering in the URL to the
search page in your web browser. For example, if you uploaded
your files to a sub-folder named "search", your new search page
will be at http://www.mysite.com/search/search.asp
Enter in some search words and give it a try!
As you will notice, the default search page is fairly blank,
as it has not yet been customized to suit the look and feel of
your website. In addition to this, we would want to integrate
the search page within your DNN site, and we will explain this
Integrating your Zoom search page into DNNAt this point, you should have a working search page which
you can access and perform search queries on as seen above. You
can use your search page just as it is, and simply modify the
"search_template.html" file to match the look of your site.
However, if you want to further integrate the search page inside
your DNN website (so that it will maintain the same skinning and
various modules you are using), then read on.
First, we need to "Add" a new page in DNN to serve as your
new Search Page. This will contain a search form, and your
search results. You can name this something appropriate like
On this new page, we will need to add an IFRAME module (if
you do not see "IFRAME module" in the Modules dropdown, you will
need to login as "host" and "Install additional modules"). You
can title this added module as "Search" or something similar.
Now click on the "Edit IFrame Options" button.
Here you should specify the Link Type as a URL, and copy and
paste the URL of your working search page (from before) in the
"Location:" text box as seen below. For the width, specify
"100%" and we recommend a decent height of something around 600
Next, click on the expand box next to the "QueryString
Parameters" heading. We will need to add all the parameters that
Zoom will use so that the page can pass these parameters along
to the actual "search.asp" script within the IFrame. Click on
the "Add QueryString Parameter" link and specify the following:
This allows the main search query to be passed to this page.
If you would like to have more parameters in your custom search
forms (search forms that you will place on other pages of your
site), then you will need to add them here as well. If you are
not familiar with the idea of the custom search form or what
other parameters are necessary, don't worry, as this will be
explained a little later below and you can come back here to add
more parameters as needed.
Now click "Save" to return to your search page. You should
now see your Zoom search page loaded within the IFrame of your
DNN search page!
Run a few test searches and you should find that everything
should be working within your new DNN search page.
If you wish to modify the text or layout (or the colours and
fonts of the search results) within the IFrame, you will need to
change the "search_template.html" file. Please see chapter 6 of
Guide ("How do I customize the look of my search page?") for
Note: You may notice that when you click on
a search result, the link opens within the IFrame of the search
page. If you wish to change this behaviour, go to the Zoom
Configuration window, and select the "Search Page" tab. Under
"Results linking", change the selected option to "Frame or
window:" and enter "_top" (without the quote characters, but
note that the underscore is important) in the text box next to
this option. Re-index your website and upload the files for this
change to take effect. You will now find your search result
links will open outside of the IFrame.
Additional note: If you make the IFRAME very
tall, you'll find that when you click on the "Next >>" results
link down at the bottom of the search results page, the browser
would not scroll back to the top of the frame automatically. To
fix this, edit your "search_template.html" file and replace the
<body> tag with the following:
Adding search boxes to your other web pagesYou may now be wondering how you can add search boxes on the
other pages of your website. These boxes are often a simpler,
smaller version of the search box you see on the search page
that allows people to submit a simple search query from any
where on the site. It will then take them to this search page
with their results.
To do this, you simply need to add the following HTML in any
existing Text/HTML module (or a new Text/HTML module):
You will need to replace the URL in the above HTML (in
green) with the actual
URL to your DNN search page that you created earlier (easy way
to find this is to go to your new search page, and copy the URL
from the top bar of your browser). Replace the URL in the above
HTML with your own, but make sure to retain the "?zoom_query="
part at the end.
(Note that the above search form does not take over the
"Enter" key. We provide this minimal HTML to prevent disturbing
other other form elements on the same page. But if you wish to
be able to submit your search by pressing the "Enter" key, see
Save your changes, and you should now have a working custom
search box on your DNN page!
You can place this search box on any of your other pages, or
make it part of your template/skin.
If you wish to create a custom search box which has more
options (such as changing between "match any search words" and
"match all search words", or having category boxes, etc.) you
should refer to
this FAQ support page on defining the search form HTML. As
mentioned before, this involves the use of additional "zoom_"
style parameters and you'll need to make sure you have them
added to the QueryString parameter section in the IFrames
settings (see above).
Now you have a very own custom search engine as part of your
DotNetNuke site! I hope the above has been helpful in getting
you up and running. There are many options and configurations
possible with Zoom which you can fine-tune to your heart's
content, including highlighting, categories, and more. Look into
the Users Guide for details.
Enjoy your new search engine!
TroubleshootingIf you have any problems with indexing your website, you
should refer to our
extensive online support section for help. There is also a
Discussion Forum for
seeking and sharing tips and advice.
Using the Enter key with your search formAs explained in the section above ("Adding search boxes
to your other web pages"), you will need to add special
HTML in order to add a search box to the other DNN pages of your
site. The HTML provided in the above section does not accept the
Enter key on your keyboard. This is to avoid disturbing any
other form elements on your page which might require/expect the
However, if you wish to make it so that the Enter key will
submit the query in the search box, then you should replace this
line in the abovementioned HTML:
With the following:
Again, make sure to replace the text in
green with the URL to
your DNN search page.
