jkuester opened a new issue, #5453: URL: https://github.com/apache/couchdb/issues/5453
## Description Reading the [docs](https://docs.couchdb.org/en/latest/api/ddoc/nouveau.html#get--db-_design-ddoc-_nouveau-index) for querying a Nouveau index it states that: > You can use a single string to sort by one field or an array of strings to sort by several fields in the same order as the array. Unfortunately, when I try to use more than `3` fields in the `sort` array on a query request, an error occurs in my Couch instance. ## Steps to Reproduce I have created a design doc with a Nouveau index that has the following code: ```js function (doc) { var types = [ 'district_hospital', 'health_center', 'clinic', 'person' ]; if (types.indexOf(doc.type) === -1) { return; } index('string', 'contact_type', doc.type); index('string', 'contact_type_index', String(types.indexOf(doc.type))); index('string', 'dead', String(!!doc.date_of_death)); index('string', 'muted', String(!!doc.muted)); var name = doc.name && typeof doc.name === 'string' ? doc.name.toLowerCase() : ''; index('string', 'name', name); } ``` Then, I am querying this index by POSTing the following body: ```json { "q":"*:*", "sort":[ "dead", "muted", "contact_type_index", "name" ] } ``` Unfortunately, the server responds with a `500` error and: ```json { "error": "unknown_error", "reason": "badarith", "ref": 3197294518 } ``` In the logs from my CouchDB instance I see: ``` [notice] 2025-02-28T21:00:01.823920Z [email protected] <0.10807.50> 87d80e15f1 localhost:5984 172.19.0.1 medic POST /medic/_design/medic/_nouveau/test_index 500 ok 9 2025-02-28T21:00:15.086077441Z [error] 2025-02-28T21:00:15.085810Z [email protected] <0.10928.50> c47dc7a1e9 req_err(3197294518) unknown_error : badarith 2025-02-28T21:00:15.086103849Z [<<"erlang:bsr/2">>,<<"base64:encode_list/2 L94">>,<<"nouveau_httpd:handle_search_req/6 L109">>,<<"nouveau_httpd:handle_search_req/3 L57">>,<<"chttpd:handle_req_after_auth/2 L428">>,<<"chttpd:process_request/1 L406">>,<<"chttpd:handle_request_int/1 L341">>,<<"mochiweb_http:headers/6 L140">>] ``` There are no errors in the Nouveau logs (only `200` successes). If I repeat the request with only 3 entries in the `sort` array, it succeeds (regardless of which field I remove from the array). ## Expected Behaviour I expect the `sort` array to be able to support a reasonable amount of sort parameters (>3) without erroring. ## Your Environment ```json { "couchdb": "Welcome", "version": "3.4.2", "git_sha": "6e5ad2a5c", "uuid": "326d5bb8-96c4-47d4-a5c0-bade13a2c24c", "features": [ "nouveau", "access-ready", "partitioned", "pluggable-storage-engines", "reshard", "scheduler" ], "vendor": { "name": "The Apache Software Foundation" } } ``` CouchDB Docker image built `FROM couchdb:3.4.2` Nouveau Docker image build `FROM couchdb:3.4.2-nouveau` ## Additional Context I am new to Nouveau indexes and have been trying to closely follow [the docs](https://docs.couchdb.org/en/latest/ddocs/nouveau.html#ddoc-nouveau), but perhaps I missed something and am actually trying to do something in an improper way.... -- This is an automated message from the Apache Git Service.
