Class Text

java.lang.Object

com.allanbank.mongodb.builder.Text

Deprecated.

Support for the text command was deprecated in the 2.6 version of MongoDB. Use the $text query operator instead. This class will not be removed until two releases after the MongoDB 2.6 release (e.g. 2.10 if the releases are 2.8 and 2.10).

@Deprecated
public class Text
extends Object

Text provides a wrapper for a text command to query a collection with a text index.

The result of a text command is a document that looks like the following:

 
 > db.collection.runCommand( { "text": "collection" , search: "coffee magic" } )
 {
     "queryDebugString" : "coffe|magic||||||",
     "language" : "english",
     "results" : [
         {
             "score" : 2.25,
             "obj" : {
                 "_id" : ObjectId("51376ab8602c316554cfe248"),
                 "content" : "Coffee is full of magical powers."
             }
         },
         {
             "score" : 0.625,
             "obj" : {
                 "_id" : ObjectId("51376a80602c316554cfe246"),
                 "content" : "Now is the time to drink all of the coffee."
             }
         }
     ],
     "stats" : {
         "nscanned" : 3,
         "nscannedObjects" : 0,
         "n" : 2,
         "nfound" : 2,
         "timeMicros" : 97
     },
     "ok" : 1
 }
 
 

The TextResult class wraps a single entry from the results array.

Since:

MongoDB 2.4

API Warning:

This class is NOT part of the Public API. This class may be mutated in incompatible ways between any two releases of the driver. This class WILL, eventually, be part of the driver's API. Until MongoDB Inc. finalizes the text query interface we are keeping this class out of the Public API so we can track any changes more closely.
