Should probably throw something here if it isn't supported?

Outdated

LogicalNode::children is public, so it should be fairly straight forward to append any additional conditions beyond the first two. Same with the handling of "$or" below.

I think these types of conditions should be throwing "invalid query" or something similar rather than asserting. But not blocking.

Could you test a few non-happy paths to make sure that a reasonably worded syntax error is thrown?
Suggestions:
{ "non-existing-property": "something" }{ str_col: { $regex: "(?i)a(?-i)cme" } }(non-supported query operator "$regex"){ "mal-formed-bson" : }

Let's not merge this yet. |

@jsflax What is going to happen with this PR? |
|
Unclear right now– we need to road map this before moving forward with the actual feature. However, if this is adding enough additional useful stuff, I'd be fine removing the MQL features from the header and then consider merging the rest. |
|
@jsflax you mean removing the changes to results.hpp? I am not sure what the risk of keeping it would be. I would prefer that we can keep the test. |
