Go中数据存储区查询中的不平等

I'm implementing queries to datastore in Go, but the inequality operator is not working as expected.

Here's my code

query2 := datastore.NewQuery(MetaData)
if !hasAccess {
    for _, zone := range filters.Zones {
        query2 = query2.Filter("Zone <", zone)
        query2 = query2.Filter("Zone >", zone)
    }
}

The result always returns nil even though I have data in datastore that matches that criteria (Zone != zone).
