No result returned from the nest c# elasticsearch query - c#-4.0

Question

I am indexing an attachment field. The POST query in sense returns expected resultset.
My query is
POST /mydocs/_search
{
"query" : {
"bool" : {
"must" : [
{ "match" : { "file.content":"abc"} },
{ "match":{"otherDetails":"asd"}},
{ "match" : { "filePermissionInfo.accountValue" : "xyz"} }
]
}
}
}
I need to convert it to a c# Nest code. I tried converting it, but its not returning any result,even it contains data. If I remove the
m.Match(mt1 => mt1.Field(f1 => f1.File.Coontent).Query(queryTerm))
from the below experssion, it returns a result set. Is there any problem with the attachement field?
client.Search<IndexDocument>(s => s
.Index("mydocs")
.Query(q => q
.Bool(b => b
.Must(m =>
m.Match(mt1 => mt1.Field(f1 => f1.File.Coontent).Query(queryTerm)) &&
m.Match(mt2 => mt2.Field(f2 => f2.FilePermissionInfo.First().SecurityIdValue).Query(accountName)) &&
m.Match(mt3 => mt3.Field(f3 => f3.OtherDetails).Query(other))
)))
);
My mapping is
{
"mydocs": {
"mappings": {
"indexdocument": {
"properties": {
"docLocation": {
"type": "string",
"index": "not_analyzed",
"store": true

It looks like the query hasn't been translated to NEST correctly. In the query you have
"filePermissionInfo.accountValue"
but in the NEST query, you only have
f2 => f2.FilePermissionInfo
which would result only in filePermissionInfo. You need to change this to
f2 => f2.FilePermissionInfo.AccountValue
