Hi to all..
First , I hope to be in the right place of the forum...
I need to develop/implement a text-html module without the ISearchable implementation in a customer site, possibly without recurring to buy one.
I could create a new module definition with no specified Businness Controller Class, but in that way I'll also loose the IPortable Implementation, and I'd prefer to keep the possibility to import-export content..
I downoloaded the source version of dnn and looked across the internet, but I wasn't able to find the source code of the TextHtml module provided with DNN, only compiled version and .dlls.. does anyone knows if and where can I find what I am looking for? Am I just blind and the source codes are just there? 
Substantially I just need to do a copy/paste (and rename to avoid conflicts with namespaces and so on) of the html module source code removing the Isearchable implementation. If it makes the difference, I'm going to use the module in a DNN 5.01.04 portal.
In alternative, does anyone have suggestions to do what I'm trying? I just whant that some specified text modules, which are displayed in all pages, to be excluded from the indexing process, in order to avoid unuseful/unwanted/redundant matches in the Search Result page...
Thanks in advance,
Alberto.
