[FEATURE] Support range queries

[hughbe]

I’m trying to migrate a library from 7.x to 8.x. However, I cannot find support the date_range query in the new version of the library.

Will support for this query be added?

Having the same problem, just switched back to the 8.0.0rc2 where the data range query is available and working.

Same here - cannot find the range query. Was it removed after 8.0.0rc2?

[stevejgordon]

This was removed after RC2 as we found some edge case bugs with the generated query that meant it wasn't fit for the final release. We documented the supported queries for the 8.0.0 release. We will (re)introduce this (and other) query types in future client releases. Thanks for raising your need for this type, as it helps prioritise that work.

Was the support for numeric range queries also removed? Any estimates on when it would be added? I might be missing something but it doesn't seem possible to create custom queries for to implement the missing queries in userland in the meantime.

[stevejgordon]

Numeric range queries are tied into date range queries due to the way these are modelled on the server (as a polymorphic range type). That is, in fact, the cause of the edge case bugs we identified, which meant we didn't ship support for these queries yet. As we highlight in the release notes, if you require such features, it's best to wait until the client supports them. These will be a priority for us as a core query type. In the meantime, you can use the 7.x client in compatibility mode. It is also possible to drop down to the raw transport layer to send/receive JSON if you prefer until these are supported in the strongly-typed client.

var bytesResponse = await client.Transport.PostAsync<BytesResponse>("my-index/_search", PostData.Bytes(requestBytes));

Alright, thanks for the quick reply! I'm considering using 7.x for now then. I guess it'll take some time for the attribute based mapping to get into 8.x as well?

[stevejgordon]

@andersekdahl That sounds like the correct approach for now. Attribute-based mapping is one of the features we are dropping, so that will not return for 8.x.

[andersekdahl]

I ended up with 8.X instead as I implemented my own attribute based system. Still missing range queries though, any estimate on when that will end up in the SDK? I know I can send queries manually like in the example above but I don't want to generate the entire request body myself just because I need one range filter. Or do you have a snippet I can use to first use a BoolQuery and then patch the JSON with a range query?

If the query classes weren't sealed I could make my own temporary subclass but that doesn't seem possible unless I'm missing something?

Are there any updates on this issue?

[stevejgordon]

We don't have an update on timescales for this work and continue to recommend 7.x client until we're in a position to prepare a release with the next set of missing features.
