The documentation for text indexes says that "A collection can have at most one text index," but I can create several without receiving any kind of error message. I receive an error message only when I try to do a text search.
> db.tc.findOne()
{ "_id" : ObjectId("52447ea78917a9cc8fdf516a"), "a" : "asdf", "b" : "qwer" }
> db.tc.ensureIndex({"a":"text"})
> db.tc.ensureIndex({"b":"text"})
> db.getLastError()
null
> db.tc.getIndexes()
[
{
"v" : 1,
"key" : {
"_id" : 1
},
"ns" : "qa370.tc",
"name" : "_id_"
},
{
"v" : 1,
"key" : {
"_fts" : "text",
"_ftsx" : 1

"name" : "a_text",

It seems as if it would be better to print an error message as soon as a second text index is attempted and especially not build or maintain the second index at all, which seems like what's happening here.
