I have a few powerpoint files that display strange strings into their summary results in the search results page.
For example for one document i see:
… 9dac618c-c4b7-40c2-8601-0d42a3200557,4;a514988a-d921-461d-837a-3b0cc8861300,6 … From the main menu go to …
The bold letters mean nothing to me - when searched within the powerpoint document they don't appear anywhere. If I open the ppt with notepad++ and search for the string, I get to a tag called "LongProp" within "LongProperties" which does contain the strings (along with 40 more of the same kind).
My question - is there a way to exclude these strings from being indexed. I can't find a crawled property with 'long' in it to match it with the ExcludeFromSummary property. I also tried to delete the tag from notepad++ but the file doesn't open anymore.
I am using sharepoint foundation with search server express.
