I am using TermsFacetFor to create a facet,
 MyFilter.TermsFacetFor(x => x.MyField, facet => facet.Size = 25).

In the EPiFind, my data for MyField is some thing like 
for product1 > "Paperback"

for product2 > "paperback".

Now both string are same only differnce is in terms of the case. TermFacetFor creates 2 different facets.

How can do that it should be consider as single item?

MyTermsFacetsForWordsIn is works fine but it creates 2 terms if we have space in field, e.g. value for MyField : "Digital Download" then terms "Digital", "Download"

Many Thanks
