I also need/want to track "log" type activities, phone calls etc., and have them findable when I need them. I use GoldMine for the contact heavy lifting, but for more general things I use Notepad. I attach a Notepad document to each MindMap that I work from, and using a sneaky tip that I found somewhere: If you put ".LOG" (note the initial full stop/period) as the first line in the Notepad document and save it, next time you open the document it will add the date/time on a separate line ready for text entry.

This way any conversations, comments, log entries are saved with date/time, and are indexable by X1 or your DTS tool of choice.

Unfortunately the iFilter does not index the contents of the topics etc. inside the maps but it does include all the metadata (title, keywords, filename etc.).

So the 'search list' that Rick currently does via the Word document is fully handled.
Just type *.mmap in the MS DS search and you get a list of all maps on your system.
And of course, add other words to narrow down your search if desired.

The iFilter is free for non-commercial use.

Haven't had the time to try it out but it should be worth a try. Not sure how many DS engines support it but Google does and I believe also MS, since it is an extension of the Microsoft Indexing Service.

Any body else had experience with this yet?

I was also considering it in the beginning but did not go for it, for that reason. I still separate reference material from project material. All project maps are then in the same folder and they are referenced through my hierarchy that starts out in my map central (which points to projects, references etc.).

I have not found an optimal way to handle project support material though.

To get around the find-ability, I put a self-referencing hyperlink on the title topic, and then export the map to word (using the same file name, same location). I can then search for something in X1, find the appropriate word document, click on the hyperlink at the top, and open the MindMap.
