Do text indexes support partialFilterExpression?

[Cyril Auburtin]

It's not mentioned in the Docs (for partialFilterExpression or text indexes), but it seems not working with:

> db.txt.find()

> db.txt.createIndex({a:'text'}, {partialFilterExpression: {a: {$type:'array'}}}) // only text index for doc with a as array

{

        "createdCollectionAutomatically" : true,

        "numIndexesBefore" : 1,

        "numIndexesAfter" : 2,

        "ok" : 1

}

> db.txt.insert({_id:1, b: 'oko'})

WriteResult({ "nInserted" : 1 })

> db.txt.insert({_id:2, a: ['ty', 're']})

WriteResult({ "nInserted" : 1 })

> db.txt.find({$text:{$search:'ty'}})

Error: error: {

        "ok" : 0,

        "errmsg" : "error processing query: ns=test.txtTree: TEXT : query=ty, language=english, caseSensitive=0, diacriticSensitive=0, tag=NULL\nSort: {}\nProj: {}\n planner returned error: failed to use text index to satisfy $text query (if text index is compound, are equality predicates given for all prefix fields?)",

        "code" : 2,

        "codeName" : "BadValue"

}
