There is no Label defined for $or in the C++ driver. This wouldn't be such a problem if there was proper documentation on how to build or-queries using the C++ API or a general note how to replace missing labels with their text equivalent. |

The code for the server is essentialy a large example app using the C++ driver. You just need to grep around the source. |

But they aren't directly visible on the website. |

there are a bunch of examples here http://github.com/mongodb/mongo/blob/master/dbtests/jsobjtests.cpp#L813-871 |

I think what was most confusing to me is that I couldn't find an example that used the normal "$predicate" syntax for the C++ API. |

An OR labeler wouldn't help much since it would still need to take a BSON_ARRAY of BSON objects. If you have a good idea for a simple syntax please let me know. As for how to construct queries I'd suggest looking at http://www.mongodb.org/display/DOCS/Advanced+Queries. The labelers only convert from something like BSON( "age" << GT << 24) to something like BSON("age" << BSON("$gt" << 24)). |
