Description
Build:7.0.0 build 2016
- Load dataset attached
- Create default fts index with keyword analyzer:
{
"type": "fulltext-index",
"name": "default_index",
"uuid": "5005f41409c983df",
"sourceType": "gocbcore",
"sourceName": "default",
"sourceUUID": "b08aa384fdcd7adfdfe3569237428631",
"planParams": {
"maxPartitionsPerPIndex": 171
},
"params": {
"doc_config": {
"docid_prefix_delim": "",
"docid_regexp": "",
"mode": "type_field",
"type_field": "type"
},
"mapping": {
"analysis": {},
"default_analyzer": "standard",
"default_datetime_parser": "dateTimeOptional",
"default_field": "_all",
"default_mapping": {
"default_analyzer": "keyword",
"dynamic": true,
"enabled": true
},
"default_type": "_default",
"docvalues_dynamic": true,
"index_dynamic": true,
"store_dynamic": false,
"type_field": "type"
},
"store": {
"indexType": "scorch",
"mossStoreOptions": {}
}
},
"sourceParams": {}
}
- Create GSI primary index
- For the below Flex queries, fts index is considered but returns 0 results but GSI do returns 71 results
Number of results from flex query: select meta().id from default USE INDEX (USING FTS, USING GSI) where ANY v IN languages_known SATISFIES v = "Japanese" END is 0
Number of results from gsi query: select meta().id from default USE INDEX (USING GSI) where ANY v IN languages_known SATISFIES v = "Japanese" END is 71
Explain plan:

"cover (any `v` in (`default`.`languages_known`) satisfies (`v` = \"Japanese\") end)",
