Values are not crawled as multi- valued using fast content SSA.
Here are the sceneries :-
• Created a list with two columns, one with lookup and one with MMS. Both are set to use multi value.
• Added few items.
• Did full crawl with FAST content SSA. Fund that it was crawled as Multi-valued as NO
• Now did a full crawl with SharePoint SSA. Fund that it was crawled as Multi-valued as YES
Now when search for content we don’t get data where we have multiple value s.
Solution :-
When you add a crawled property in a managed property try to add both with (TEST) and (), do a full crawl .
By doing this we can get the multiple values but the only issue is the values will not be separated by any spl characters.
Then other way to accomplish it to use custom processing component.
