标签实施

Question

I am not quite sure what is the correct title for my question. I wanted to implement the tag system just like what is used in this website. I found the way to implement it eg How to implement tag system .

In this website, when you type in a 'tag' term then hit enter or spacebar key, the the 'tag' become 'something' that you can click an x to delete it. My question is what is this 'something' and how can I implement it or get things started. I work with C#, ASP.NET but any other techniques are mostly welcomed.

I have tried to search but I don't even know what the thing I want is called/referred as....

Thanks,

LT

Loosely related to your question...

The question you linked to shows how you could do it using a SQL database, and there is nothing wrong with using structured data if that is what your requirements are.

However, another option is to make a faceted search system using a search engine (unstructured data) rather than structured data. That is more or less how the tags on SO function, because you can combine tags to narrow your results.

I have recently completed a .NET port of the Java Bobo-Browse faceted search engine, called BoboBrowse.Net , which is available on NuGet . BoboBrowse.Net is built on top of the Lucene.Net search engine. The documentation can be found here .

Faceted search is much more powerful than a simple tags system, and allows you to make "checkbox style navigation", "drill-down search", and even define ranges of items to search for. Here is an example of such a system .
