I'm doing a recommendation engine and I need to access the Enterprise Keywords of a document and search for other documents having at least 1 matching keyword.
So for example I have
Document A which has the following Enterprise Keywords:
- Keyword X
- Keyword Y
- Keyword Z
Then I need to search the whole Site collection for documents having at least one of those keywords. If it's possible to search for all of those 3 tags with an OR and returning all the documents that have at least one match ordered by number of matches, that would be great. If not, then I can do it one tag per query.
I cannot find how to query only for Enterprise Keywords.
So, which is the proper and fastest way of doing this? (The site is not using FAST).
