First, did you start mongo with textSearchEnabled=true (see Enable text search)?

If you're using a config file (e.g. /etc/mongodb.conf) the correct line should be:

setParameter = textSearchEnabled=true

Second, your index looks like a regular index rather than text. Please post the command you used.

If you want to test the text index function, try the following:

Drop your current index (it may interfere with the new one you'll create)

db.items.dropIndex("type_text_color_text_category_A_text_category_B_text_category_C_text")

and create a new one

db.items.ensureIndex( {type:"text"}, {unique: false, name: "type_index"})

and then try the search again.

You may also need to run db.items.reIndex().
